Denon Exercise Freak Headphones


Price as reviewed:


Once familiar with the button location and function, controlling volume, skipping tracks (backwards and forwards), and pausing and answering calls is very easy.

With no cables, there is no untangling hassle. We tested to around the three-metre mark and the connection was still strong.

Using Bluetooth does require headset recharging – every seven hours (claimed). We’re up to five hours and they’ve not skipped a beat.


It's not exactly Bang and Olufsen sound quality, but certainly audible, even above the noise of rushing wind or turbo din - though our attempt at answering a call while going downhill wasn't successful; the caller couldn't hear us.

    I’m of the belief that common sense should prevail, I hardly ever go out without the radio/Talk sport in my left ear to keep me company, I agree, you would not want to have both ear pieces in with loud music distracting from traffic noise, having said that you can compensate anmd ride with more awarensss, you would not tell a deaf person he could never ride a bike or drive a car would you?

    On today’s roads, anyone listening to music on headphones while riding is just plain stupid. It dangerous to say the least. It is also impossible to hear the sounds of the countryside which add to the pleasure of cycling. It is bad enough when cars zoom past and you can hear them coming. It is frightening when you don’t know they are coming.

    Mikey G, I don’t need to hear the traffic when i’m overtaking it.
    I do agree with you though.

    I use headphones and listen to podcasts on long rides – pause them when going up hill or through town centers.

    The key is absolutely the volume level – you can find a sweet spot where you can hear what you are listening to, traffic and the sounds of nature. I was against this on principle of safety initially and still am if someone just has it on full blast – but the point Im making is yes its possible to hear all and ride safely – with common sense of course!.

    My opinion is no more ridiculous than yours Bryan. Also I don’t believe Mr Froome listens to music when he is racing, but if he did he would still be safer than the average rider using headphones on the road, Pro Racing is on traffic free roads roads.
    As far as I am concerned “anything” that distracts from my awareness of what is going on around me, when I am riding on Britain’s crowded roads, is just that, a distraction. When I have to use the turbo trainer music is my friend as it relieves the boredom or eases the pain of an interval session. Everything has its place.

    Considering Chris Froome uses music as both a motivation and a rhythm (though I think listening to his drum and base for hours might cause me to climb off!), I think some of the notions expressed here about using it whilst riding are frankly ridiculous.

    It depends where you are riding, maybe you don’t want to hear the damn sheep. Also useful for pre-race warm-up, and getting into the right mood.

    Mike- I ride with headphones in and I can hear the music loud enough over the wind, while I can also here traffic coming up. If conditions are poor I may sometimes take out the right ear to listen out for traffic and this is probably advisable for most on busy roads.
    As for the reasoning, well when I am doing long 3-5 hour rides in poor conditions by myself then sometimes the love of riding really doesn’t come close to cutting it, so music makes it that bit more bearable. Also there are many studies to suggest listening to music can add motivation and improve concentration. When it comes to doing hard hill repeats by myself I find good music is invaluable and really helps me dig that little bit deeper when it is a good aggressive song.
    However I do all this with my £10 headphones… £130 seems rather steep!

    Totally agree with Mike…. Listening to loud music while out on the roads (running or riding) is akin to subscribing to a death wish

    I have to ask the question. What are people doing using headphone to listen to music when they are riding? Firstly, If you can hear the music loud enough for it to be worthwhile it will greatly impair your ability to hear vehicles around you. Secondly, if you dislike cycling so much that you need to listen to music to make it bearable, don’t do it.
