One side was dead out of the box, very upsetting that the person who received it for Christmas opened it up charged it, got ready for a jog and the one side was just dead..so lame.

Horrible audio and buds that are uncomfortable and do not stay in your ears. I returned these immediately, at least the return was hassle free.

These broke less than a year of use in. Before that, they were good. Very disappointing considering the quality and durability of other Anker products I own.

I wrote a fine review and they did not accept it. Gave it two stars, now I'm giving it one.My headset looked like there's hairs on it. And other stuff I don't understand. See pictures

I've used alot of Bluetooth earphones in the past. I've had terrible ones, good ones and "meh" ones. But this is by far the worst set I've ever used by leagues (in terms of audio quality).

I didn't like these as they kept slipping off my ears annoying the crap out of me and the sound was terrible.

I actually love these there are a few things here and there but for the most part these things are pretty good.*Update* Finally going to get my money back from Anker for this item. I complained to them multiple times about many issues with these earphones. Each time they were really resistant about replacing. They even tried to charge me for ear pieces on these. Even though I told them that the right piece continually comes off. Also complained about short range, cutting out, randomly not working and short battery. At NO time did they send a replacement. Just a bunch of resistance and the 3rd degree from them. I put up with issues from these for months. I use them for daily routines, for work and working out. The ear piece on the right hand side tend to come off. If I'm lucky it's still in my ear. If not I'm in for a search.When they work, the sound with these is phenominal. Especially on my Ipad Mini. Over time of using these I've had to adjust it more. Either that or my sessions are getting more random. Jump roping they'll make their way off. And it's always the same side. The range was pretty good, but it got shorter over time. I used to be a fan of Anker but lately it's like a totally different company.

Sound died in one ear after about a month of running. Seems to be low quality and unreliable.

All other features on this device are fine, but the design is so poorly constructed that my ears are in pain after 15 minutes of use. Regrettable because I really was a fan of Anker's SoundBuds Curve earbuds that they no longer produce.

The package arrived without half the things mentioned. No additional buds, no USB charger cable, no spare "FitClips". Its not a big deal but if it matters, don't bet on them coming with itEdit: Nevermind. These are Chinese trash. Stay away. It refused to connect to my device after a single day. I charged it and it didn't work for very long after.
