You know that moment when you hear a song you've loved for years and suddenly you notice something new? A harmony over in the left channel, a faint acoustic guitar, a breath before the chorus. That's what I love about Sonos. Their speakers are designed to connect you to the details that make music feel alive.

The stories behind the world's most iconic and fascinating sounds.
Dallas Taylor
I'm Dallas Taylor.
David Jeffers
I vowed that if somebody wanted to hear my story, I was going to keep it real with them and let them know what things are really like. My name is David Jeffers and I'm a sound designer.
Dallas Taylor
David has worked with companies like Google, Meta, the YMCA, 23andMe, and many more. His sound design style is always very musical, which goes back to his childhood.
David Jeffers
Around my house, music was always going. My dad had a record player and he played music all the time. My older brothers, they started getting into hip hop. So I wanted to be like them and started listening to hip hop. One day, I guess around seventh grade, I met my friend Ricardo. For some reason we just got the idea like, hey, let's make some music. He was an emcee. I was a fake dj. I say that because I never was that great at actually DJing. We ended up taking a music class in high school in our ninth grade. And that was like really the jump off of producing. We had two tape decks and we bounced tracks back and forth on this tape deck to make beats using a DJ sampler. So we started out doing that, saved up some money and we bought a Fostax 4 track and we started making these remix tapes. So we started selling these remix tapes at lunch and promoting it. We ended up getting one of our remixes to like number three on the local college radio.
Dallas Taylor
At the same time, David was also building and installing sound systems.
David Jeffers
Anytime my parents or somebody was throwing something away, I'd want to take it apart, see how it worked, see if I could build something with the junk parts. So I think it was just in my DNA. 8th or 9th grade, I made my first speaker box, got really into it. So when I got my first car, I bought it when I was 14 for my older brother. By the time I could drive it, I ended up with like two 15s and a 78 Volkswagen Rabbit
Dallas Taylor
for reference. Those are huge speakers for a very small car.
David Jeffers
The first time you get in a car and you just feel that power, it was loud. It felt rebellious and almost was like a mini concert.
Interviewer
At what point did you meet your wife? Where were you and when did you meet her?
David Jeffers
The first time or the second time?
Dallas Taylor
Ooh, let's start with the first time.
Interviewer
I want to hear both times.
David Jeffers
All right. Well, the first time I was a senior in high school and she was a junior in high school. We went to two different high schools, and I guess because of friends was real popular at the time. We found ourselves hanging out at this local coffee shop. One day, we're just hanging out, and I see these two girls come into the coffee shop. I'm like, oh, man, she's pretty. You know, I wouldn't mind talking to her. But, you know, I wasn't like the girl crazy, just walking up to girls and talking to them. So my friends were like, oh, we're gonna hook y' all up. You're gonna talk to her. So my friend basically makes the introduction. So that's how we first met. We went to the movies, and it turns out she was spending the night at a friend's house who went to a club. So she couldn't go home until her friend got back. So we ended up staying out super late waiting for her friend to get back. I get home, I get in trouble for staying out too late. And that kind of soured things for me on the first go around. So we really didn't talk too much after that.
Dallas Taylor
Soon after, David and Ricardo graduated high school and David left for college.
David Jeffers
So I go off to A and T, and that's in Greensboro. My sophomore year, I'm walking across campus and guess who I see? My current wife, Yasmin. And we started talking, and pretty quick after that, we were dating.
Dallas Taylor
In college, David studied mechanical engineering. What did you think you would be
Interviewer
doing with that mechanical engineering degree? Like, what was your goal at the time?
David Jeffers
To get a design position at an automotive company. You know, I love cars. That's another one of my loves. Honestly, at that young age, I just was like, any way I can get in, I'll be happy with it.
Interviewer
Do you see that connection between that systems based thinking and the way that you approach sound design now?
David Jeffers
Oh, yeah, definitely. You know, I'll look at something that needs to be sound design and try to, like, picket it apart into individual components and then try to rebuild the total sound, combining different components of sound to make the final product for lack of a better word.
Dallas Taylor
After college, David and Yasmin moved to Detroit, where David worked for Ford.
David Jeffers
I actually landed up in vehicle testing, which was really fun and interesting.
Sponsor/Producer Voice
Then one day he got an email from his old friend Ricardo.
David Jeffers
He was like, hey, man, we need to crank this machine up. We need to do some more music. And we started a online record label called Nablina Records.
Dallas Taylor
Nablina was an underground hip hop label that David and Ricardo led in the early 2000s. This track is from one of their compilations. It's called Forward by Canadian rapper Eternian.
Eternian
Yeah, Spectacular with the vernacular. You know I rock it Another diddly for that digiplayer in your pocket on top of the rhythm Filling it with the rhyme don't stop it, lock it down.
Interviewer
How does that hip hop background influence your sound design approach?
David Jeffers
My style of hip hop production was primarily sampling, and I feel like sound design is really just sampling on a whole nother level. You're taking bits and pieces of sound from, from all these different places, putting them back together to make something new and something beautiful.
Dallas Taylor
While David enjoyed his job at Ford, Detroit wasn't the right fit for him and Yasmin.
David Jeffers
So her mom had moved to Charlotte, North Carolina. So I was like, hey, why don't you move with your mom, try to find a job and then I'll try to find a job down there.
Dallas Taylor
So Yasmin relocated to Charlotte, and David soon followed. They got married and had their first child.
David Jeffers
So at that time, I was working at a bearing manufacturing company doing test engineering. It wasn't my dream job, but that was when family life was really my main focus. My oldest son, Jackson, he was 2 years old at the time, and Yasmin
Dallas Taylor
was pregnant with their second.
David Jeffers
So it was 100% dad mode at that time.
Dallas Taylor
And then came the most pivotal day in David's life.
David Jeffers
We were planning a big, I would say my first real family vacation. And we were headed to the beach. It was actually our first day really being there at the beach for a full day. The water's kind of rough. Tide's coming in. Really not too many people in the water, but I decided to go in and Jackson, he's playing in the sand on the beach. My wife is chilling with Jackson, and my nephew, who was about 15 at the time, was there hanging out with us as well. I was in the water and I saw a big wave coming. And you know how you can dive through the wave to kind of cut it so it doesn't hit you so hard. So I've Done that a million times. So I go. I dive through the wave. And I didn't know it, but apparently there was a sandbar or something just ahead of me where I dove. And I hit my head on the sandbar, and immediately I knew that was it. I couldn't move. I couldn't do anything. And I'm in the water just like, oh, my God, am I gonna drown? You know, please don't let me Dr.
Interviewer
Were you in pain?
David Jeffers
No, Actually, it was the crazy part. I really did not feel anything. I don't remember being in any kind of pain.
Interviewer
Are you able to call out or anything? How did you get out?
David Jeffers
Yeah, luckily, since I was on the sandbar, it wasn't that deep. I was able to call out to my nephew, and he thought I was playing at first, and so he didn't come immediately. And then all of a sudden, I guess he realizes, you know, like, I'm not moving. And my wife kind of stands up and she realizes. And so my nephew gets over there first and tries to pull me out.
Dallas Taylor
This is Yasmin's recollection of that day from a documentary about David.
Yasmin
My nephew was able to pull him out of the water. And David said to me. He said, I'm sorry. He said, I just ruined our lives. And I said, no, you're probably just in shock. Like, there's no way. And he's like, no. He said, I broke my neck. I hurt it. I'm sorry. I have ruined our lives.
David Jeffers
I remember being on the beach. A couple people came over, and luckily, a lady was on the beach that happened to be a doctor, and she was like, stop. Don't move him anymore. You can make it worse. Then after that, things get a little bit foggy, but I'm still there. I'm still awake. And I remember getting on the gurney, and they had to take me up to a parking lot where this crazy wind just started hitting me in sand because, you know, they had to call a helicopter. And the last thing I remember is being in the helicopter. And I think at that point, they gave me some sort of pain medicine or something to knock me out, I guess. But that's when I don't really remember a lot from there until I'm actually at the hospital about to go into surgery.
Dallas Taylor
That's coming up after the break. When you're running a small business, it's easy to get bogged down in the busy work for me.

Interviewer
Okay, so there's a helicopter that takes you to Wilmington to put you into surgery. And I'm assuming surgery is to examine the extent of the damage or keep it from becoming worse in some way?
David Jeffers
Yeah, I guess it was both to see the damage. I'm assuming they did scans and all types of stuff before the surgery, but they had to put fixtures in my neck to help everything heal because I shattered one of my vertebrae and cracked another one. So now I have a fake vertebrae and some metal structure in my neck to kind of hold all that together. And I also had to get a halo, which is you've probably seen in movies on tv, the big thing that goes around your head into your shoulders. So basically, you can't move your head at all.
Interviewer
So there's this period of recovery. Can you tell me where your mobility ends exactly?
David Jeffers
Basically, just right after my shoulders, around my nipple line is about where it stops. Even, you know, like, my arms as a quad, I don't have full function there. I don't have triceps. My hands really don't have any function, no finger function. So my main muscles of use are my shoulders at this point.
Interviewer
Okay. I was under the assumption that you had mobility on your thumb and top fingers, but not your bottom. But I'm incorrect on that.
David Jeffers
Yeah, that's what you call. I call it the fade grip. The technical term is teno DEIS grip. And it's basically if you flex your hand up, bend your wrist, your tendons will pull your fingers in and your thumb in. So it gives you a little bit of a grip. It's not really strong. You know, I could pick up some things, but, yeah, I can move my wrist, flex it up, but I can't forcefully bend it down, if that makes sense.
Dallas Taylor
David spent four months in the hospital and as you could imagine, it was a dark period. He had to reevaluate his whole life and what those changes would mean for his kids, for his marriage, for his work, for everything.
Sponsor/Producer Voice
David.
David Jeffers
It's just a total flip of life when this happens. I felt like I lost my identity. I didn't know who I was.
Dallas Taylor
Coming home from the hospital was just the beginning of a long recovery journey. Physical and occupational therapy, retraining the muscles that he still had access to, navigating the world in a powered wheelchair, driving a car with hand controls, and finding a new career path.
David Jeffers
After the injury, I didn't know what I was going to do for work at all because at the test facility, I've always been hands on. So I couldn't imagine going back to work and just sitting at a desk doing that. I didn't know how I could do it physically or mentally.
Dallas Taylor
But in those early weeks and months of his recovery, a seed was planted. With barely any ability to move on his own, he started listening more deeply.
David Jeffers
When I was in the hospital, just being in the bed, stuck in the bed for so long, I started paying attention to sound a lot more. Where it got to the point where I could tell what nurse was about to come into my room based on the way they walked.
Dallas Taylor
But that seed would still take a few more years to grow into anything more.
David Jeffers
I ended up doing some engineering consultant work, like updating technical manuals for some companies and stuff like that. I did not enjoy it at all. But then, probably four years or so after my accident, once again, my friend Ricardo, you know, we're still friends, still tired as ever. He had a animation motion design company based out in la and his partner had the idea was like, your friend David, he knows how to make music. Smart guy engineering. I think he could do sound design. So they hit me up and was like, hey man, what do you think? You want to give it a shot? And that's where I kind of did the pivot from engineering to getting into sound design.
Dallas Taylor
Early in his sound design journey, David found a mentor.
David Jeffers
Ricardo introduced me to Joe Bissile. He's also a sound designer. He has his own sound design company called the Chicken.
Dallas Taylor
Joe is actually someone that I know of through Defacto sound and he's really good.
David Jeffers
And Ricardo just was like, hey, Joe, can you just talk to David? You know, just kind of answer some questions for him, you know, tell them about the industry kind of thing. When I first Started out and Joe, super nice guy, he was like, look, I will give you an hour every week to mentor, teach whatever you want to do free of charge. And basically we started doing that and until now we still do it. We've become great friends. He's taught me so much. I am forever in his debt. He's a great guy, man.
Dallas Taylor
Gradually, David picked up different sound software. He started with a simple iPad app, then moved on to industry standard programs like Ableton and Pro Tools. He also did a lot of experimenting to find a good hardware setup which he pretty much has down now.
David Jeffers
Basically it's almost like a splint that goes on my hand and down my forearm where there's a stylus in there so I can just use my shoulder and bicep and move around on the trackpad. And over the years I've gotten pretty good at controlling it. I've ended up getting a secondary keyboard where I program all my shortcuts and stuff like that. And that's been the game changer there.
Dallas Taylor
Eventually David formed his own sound design company called Quadrophonic Sound. Slowly but surely, he started making contacts and landing more gigs. Over the years he's done lots of work with Ricardo's company, Bien, which is the Spanish word for good or.
David Jeffers
Well, their whole background is inclusive motion design. Basically it means design with not for, you know, put inclusion in the process and innately it'll come out in the final.
Interviewer
Can you help articulate why that methodology is so important with not for the role of different experiences and different lived lives and how your unique process and others unique process helps drive creative.
David Jeffers
If you haven't lived it, you're not necessarily going to be thinking about it. There's a lot of stuff, me being an able bodied person for 33 years that I know for a fact that I never thought about once and definitely did not include in my creative process. For example, if you're creating an app for a phone, the spacing where you put dropdowns or selections, it's a big deal for somebody like me who might not have the fine motor skills to use it. It could make the difference of me using it at all or using it on a daily basis. I think everybody probably feels like they're empathetic to people with disabilities. But me actually living it, realizing how much it affects someone's day to day life. I spent so much time in rehab, I learned a lot, not only about my condition, but other conditions, just seeing how they work, how they live, how they do things differently. So it's so ingrained in me now.
Dallas Taylor
Recently, Behan and a company called Only Today TV collaborated on a documentary about David called Quad Life. It's a raw, vulnerable window into David's world, including his morning hygiene routine, the insecurities he still struggles with, his love for his family, and his journey into sound design.
Interviewer
I think that what struck me is just how. Gosh, just how open you are to people, seeing your real world. And I think that it just. It's so deep and rich because you are not sugarcoating it. It's something I have never seen before, and I think it grew empathy inside me. I feel close to you because you were able to open up so much.
David Jeffers
I really appreciate that because it was tough. I mean, obviously, I didn't want to do the shower scene, but I felt that it was important that people see how intricate, how humiliating, and how hard that process is that I have to deal with every morning. And honestly, it came from being traumatized by people not being real and not being honest. You know, they say comparison is the thief of joy. I learned that in such a real way after my accident. Being on social media and seeing other quads, I would be like, oh, man, me and this guy, we have the same injury, so he's doing this this way. And, you know, life is great, and it looks all shiny and normal and fun. Why isn't my life that way? And it really. I mean, it caused me to be depressed, be hard on myself. But once I realized, like, you can't compare yourself, and half of the stuff that they're saying is not really true to life, I vowed that if somebody was listening to me, somebody wanted to hear my story, I was gonna keep it real with them and let them know what things are really like. You know, you can do that and not be a Debbie Downer, because there's still a ton of joy in my life. I love my life, but there is barriers. There are hardships. And I think to be fair to the people that are listening and going through what I'm going through, I have to be honest.
Dallas Taylor
Today, David, Yasmin and their two sons still live in Charlotte, and David is grateful for how much time he gets with them.
David Jeffers
Another positive change after my accident was I was able to stay home and be with my kids. Whereas, you know, if I didn't get hurt, I'd probably be still at some boring engineering job, working nine to five, rushing home and only having a couple hours with the kids when they're young before they go to bed.
Interviewer
Even zooming out from sound like what are your favorite hobbies or what brings you joy in the creative world?
David Jeffers
I still love producing music, actually. My son, he's become an artist now as well and he's doing some recordings. So I love watching him. I love giving him advice and him not listening, but that's a big joy. And of course, hanging out with my family, doing stuff with them. My other son, he's into basketball and I've never been into sports, so I'm totally learning something totally new. If he loves it, I'm going to love it. I'm going to support him and figure out as much as I can about whatever he's doing.
Dallas Taylor
For David, it's been a long road of self discovery.
Interviewer
So this happened when you were 33, which was 14 years ago. Do you feel like you're a different person? Where are you a different person and where are you the same person as
David Jeffers
far as being the same person? My mind is fully intact. I'm still the creative, excited, fun I want to have. I want to build things. But where I'm different is unfortunately a lot of the physical things I simply cannot do or it's very difficult and time consuming to do a lot of times.
Dallas Taylor
The accident transformed David's life and in that chaos he lost himself.
David Jeffers
But actually getting into sound design is what I feel really brought me back. It just gave me a lot of purpose. I felt like my creative need to put something out in the world is being fed and that is like the great positive change. One thing that's always exciting is there's still a ton for me to learn. Whether it's just music or sound design, there's a ton of that I'm ready to explore and hone my skills on and just really make my place in the industry.
