This concept is wankers.
These things will fall out easily, especially during sport. You could easily lose one of them, and that'll be the end of it. Battery life and overall reception and sound quality being crap are the fatal bullets.
Companies, just add a wire connecting the buds... because they'll be easier to carry around. This isn't the future future.
- Why would they fall out "easily" compared to wired options?
- Why would you wear anything for sound during sport, what are you playing?
- Companies already have versions with a wire connecting the buds this is an alternative.
I own a pair JayBird BlueBuds X for running and the gym. Sometimes if I'm running on the street I'll only put 1 bud in (for safety - can hear my surroundings) - this is really awkward with the Bluebuds as the connecting cable is fairly short so the second bud just flops about. If I had something like this concept (no cable) I could just pop one bud in and put the other in my pocket.
Agree that this particular product isn't up to scratch, but let's not throw out the entire concept because it doesn't fit your use case.
