The Ultimate,

Wireless, Sweat-Proof
Fitness Headphones

Whether you’re just starting to get back into shape or training for a marathon, listening to music while you work out can enhance your performance, helping you meet your fitness goals faster.

In fact, clinical studies have proven that music enhances athletic performance by as much as 20%. We believe our Exercise Freak wireless headphones can boost your performance by much more, since there are no wires to contend with. Just go to any gym and you’ll see the common frustrations of headphone listening – cords get tangled in weights or gym equipment, make unwanted noise effects while jogging, and just generally get in the way.

Unleash your Maximum

Performance with Wireless
Bluetooth 3.0 Connectivity:

Denon’s Exercise Freak In-Ear headphones feature Bluetooth 3.0 connectivity. No more surprise yanking an earpiece out of your ear when the cable gets tangled in your arms as your walk or run, no more taping wires down on your body, no more running wires underneath your shirt, no more worries. With a range of up to 25 feet, you can even set your smartphone down on a treadmill or on the floor when you’re lifting weights at the gym for a fitness experience so liberating that you may forget where your phone is in the gym (we do recommend you keep an eye on that).

Your “Power Song”

will push you to excel, thanks to professional tuning and an integrated amplifier:

We know that the right song can be more motivating than a personal trainer. Hear it on a pair of Denon Exercise Freak Headphones and you just may put the personal trainer out of business. Exercise Freak headphones feature an integrated amplifier and are professionally tuned to provide heart-pounding bass to energize your workouts, no matter what your power song is. These headphones feature a 7 hour rechargeable battery (charging cable included) and provide audio alerts for low battery status and operation feedback.

Take back Control…

with Denon’s Integrated Controls and Microphones:

We know that for some of you, your fitness routine is the one time of the day that you get the chance to think, to reflect, and to focus on yourself. Denon’s integrated controls allow you to adjust the volume, play/pause your music and even choose to answer that phone call….or ignore it.

Secure fit and sweat

proof design allows you to focus on your workout

We are so passionate about making the best-in-class fitness headphones that we tested several design prototypes on fitness gurus as they ran, walked, lifted weights, and even did yoga and finally came up with the right design. Denon’s Exercise Freak Headphones feature a flexible neckband and articulating in-ear design to fit you perfectly. These headphones were designed to be sweat proof and feature built in air cushions on each side for comfort and added ventilation.


Back band for safe evening workouts

The Exercise Freak In-Ear Headphones also include a reflector on the neckband to provide added safety for evening workout activities. The Exercise Freak AH-W150BK In-Ear headphones also come with anti-microbial silicon ear tips (XS, S, M, L), USB Micro cable (for charging the battery), and blue mesh carrying case.

"Do you run in the Disney Marathon, walk at lunch or even run/walk on a treadmill? Heck, if you do any type of exercise the Denon Exercise Freak Bluetooth headset is for you! "
Mike Conrad, gottahavegadget.com


“The best thing about these, in my opinion, is they are light, they stay in place, fit well and they are wireless and because of these things, they are something any runner would want to consider”
Jeff Williams, Editor of Detroit Runner


“What’s cool about Denon’s Exercise Freaks is that they’re as invisible during a workout as a pair of cordless, Bluetooth 3.0 headphones with built-in rechargeable battery and hands-free call capability can be. Which is to say, until the geekerati invent an aerosol-free headphone spray for the gym, these nifty little Freaks, at $149 and available in yellow, blue and black, are a sound bet.”
David Hochman, Forbes.com


“The Exercise Freak headphones are in-ear headphones, but it’s not a tight fit—by design. The engineers know that runners need to be able to hear ambient noise (like a car horn), so while you’ll always hear your music clearly, you’ll still also be able to hear surrounding noises. What was most impressive was the play/pause button. It has a bit of an air bubble inside, so when you’re pressing down on it, the button is pushing Click on you a bit. What that means is you’re not jamming the earpiece further into your ear when you’re just trying to push the button. Brilliant design choice. They’re highly recommended, especially for regular long-distance runners who want a bit of freedom from their wires." Alan Danzis, Starpulse


"Like many traditional audio companies Denon is a relatively new player in the headphone market, but unlike its competitors it has acted aggressively within the category to keep pace with the fast moving changes that are happening within the world of personal audio.”


"For the most part, earbuds are what they are; aside from a handful of solid Sony offerings, few units impressed me this year. But Denon’s Exercise Freaks are a rare exception. These Bluetooth units are built for use in the gym, and they’re about as impressive as a pair of gym earbuds can get. The Exercise Freaks are the first unit I’ve ever used that never once fell from my head, even during hanging situps and muscle-ups.”
– NY Daily News, Ebenezer Samuel


“Another closed, in-ear fitness headphone--and one that can eliminate the dreaded headphone wire-yank problem--is the Denon Exercise Freak (around $150), which is a Bluetooth wireless fitness headphone. (There is a wire that ties the two earpieces together that goes behind your head.) An earhook design assures a snug fit. (Though it's a bit tricky at first to get the fit right, you'll get used to it in no time). For its tangle-free convenience while exercising, good enough sound for wireless exercise listening, and its Bluetooth wireless headset functionality, the Exercise Freak is a great fitness companion.”
