run with these
wow, these sound shockingly good. I'm familiar with multi-function apt-x earbuds. I go running with them, and go through a pair about every couple months. The sound coming out of these things right now is better than the four or so, semi-broken earbuds i have lying around. The bass is so bassy... (for earbuds)I don't want to make it sound like these things are the best headphones you'll encounter; but as far as earbuds go, and for this price, i'd totally but these again after i break them.This bass ... you know how your feet can hit the ground on the bass notes during a run..? These earbuds make me can't wait to do that.OHHH- and they definitely feel secure. Silicone ear spokes are barely noticeable, and the band is really light. They actually stay on better, and less noticeable than the earhook style buds i just broke. Like every silicone whatever, the band needs some breaking in before it loosens up and sits comfortably.Run em in.edit- Just came back from a run. confirmed. all facts ^^^^

Worked great for a month
These headphones worked great for a month then suddenly stopped working. It seemed as if the battery was drained as through standard use but it wouldn't charge up again. Disappointing as the sound quality and microphone quality were good for the price. I recently have cycled through multiple pairs of headphones bought on Amazon and all seem good at first, but in the end they were all cheaply made imports. I'm going to suck it up and buy airpods. I'd rather pay more and have a quality product than have a bunch of cheap products I need to replace every few weeks.

Excellent Value. Sparse instructions.
Instructions are sparse. Otherwise it works great !! I like the low profile. The fit is very good. The sound is excellent for a product under $30.

The antena is too weak
The antena is too weak. i cannot use it with the phone at the jeans' back pocket. I have to hold the phone in hand all the time.

Good buy
This product is value for money. It is really effective at cancelling outside noise and holds true to high quality sound. The magnetic feature is a bonus for active persons who may have forgotten its around the neck.
