The video may look a little like an infomercial, but the idea is interesting.  Riding safely with headphones is a problem lots of companies have been trying to solve.  Some by circumventing the noise cancelling aspect of headphones (see Aftershokz, for example) others by turning your helmet into a veritable modern day boombox (see Freewheelin, for example).  Fuser by Olens Technology, on the other hand, adds a microphone to your existing headphones that picks up the noise around you and plays it through your headphones along with your music, audiobook, podcast, etc. with volume control and a mute button.  No word on interference or what the mic sounds like with wind whipping across it, but the idea could have potential.

    There is never a safe way to use headphones and ride. i dont care what they say. Stupid people will just turn their player louder. come on use your head.

    On a trail the biggest problem is just getting users to call out their presence. anything that adds to that lack of common sense and etiquette is pretty useless. Ambient noise? You mean right before the guy on his cell ends you can hear yourself crunch?

    There seems to be lots of hard lines drawn in this community with zero tolerance for those different from us. I use headphones. Nothing you say will change my stance; nothing you say impacts me. I love the outdoors. I love music. Why must people on here piss on everything that doesn’t suit their own specific personal desire? Don’t bother replying to me directly, I can’t here you—I have BOTH earbuds in and have the volume cranked.

    Nice screen name. Anyhoo- turning up the headphones in this case would turn up the sound of the outside world as well. Come on read the post.

    Sorry but I may have to break from tradition and say something half intelligent, this technology will not predict loud traffic noise such as somebody beeping their horn or a car screeching to a halt. It cant as predictive technology does not exist as of yet that can predict unlikely events. Noise cancelling software works with predictive noise such as airplane engine noise.
    There will be a time lag between the mic detecting the sound and the software “blending” it with the players’ music. What the lag is would depend on a number of factors (direction, power, frequency) but I would rather ride with the music low or one bud removed than chance hearing something dangerous that has a time lag.

    This looks like a good product. I have been riding and running with music for over 20 years and have never had an issue with not hearing traffic. Just leave the volume low enough and you are fine. That being said, this product would give more awareness to a lot of people that are just not as aware of their surroundings while wearing headphones.

    i’ve hit guys like ryan on my bike on the trail even after calling out several corners and a whistle. i don’t mind his choice of crankin it loud(i love loud! played pantera covers in a band!) as long as he doesn’t complain when he gets wrecked.

    Riding safely with earphones has been solved for some time now. The solution is this: don’t ride with sound-isolating earphones (active or passive) and keep the volume at a level such that you can hear what’s going on around you.

    Yes, riding safely with earphones has been solved for a long time now: you don’t stick in them in yours and you don’t play music through them. Simple.

    Where’s the mic? Think about it – your ears hear in stereo and give you an idea of the direction that potential dangers are coming from. If the mic is mono and placed in the wrong place you will have no idea where the sound is emanating from.

    Good point.

    Perhaps a set of headphones designed specifically with microphones on both sides of the earpieces would be the solution. That way you are getting the sounds from the outside world from “ear level” and not from a mic that’s clipped on to your waist or some other location.

    Otherwise it’s a neat idea.

    A good way to get outside world sounds from ear level in stereo would be to not have things in your ears. If riding a bike is so boring that you need music, get another hobby.
