Build quality is good. The size of the ear pods is a little obtrusive, but the battery has to go somewhere.Sound is ok, very bass heavy with recessed mids though decent highs.My biggest gripe is the constant gain hiss when there is a stream. It doesn't matter the source, these hiss when the the amp section is on.The accessories are great. 3 sizes of tips, 3 sizes of loops style ear retention pieces, and 3 of the leg looking ear pieces.I was tempted to give these less stars then I remember how much I paid. They are good for the money.

I had absolutely poor connectivity while biking. My phone was in the back pocket of my jersey and the connection kept breaking off. It got worst the faster I went. I have a cadence sensor on my bike with a Garmin GPS. I have not synced those with my phone or the headphones. I don't see why the headphone be looking for signal or have its connectivity blocked.I am very disappointed.The finish is OK, could be better for the regular price at which the headset is sold

They just don't fit especially well in my ear, even with all the changeable fittings. The cord is a kind of rubbery texture, and it rubs and makes noise through the headphones. The volume button has three little dots that are all the same, and since it's kind of long, it's hard to tell by feel where you are on it and which way you're about to click. Maybe. It bad for the price, but just not a great design, in my opinion.

Great sound quality, great price. Also, I've confirmed that these headphones can seamlessly switch between multiple devices, allowing for a seamless integration of multiple connected devices.

The earphone is good except that the size of the ear plug is too big.

Worked great for about 2 weeks, then started dying after only a couple hours, now will not take a charge and cant be used. I consider my use to have been normal exercise. Sound and fit were both good, would have liked a low battery warning which this unit didn't have.

This item was well worth the price. It came with a very sleek packaging and easy to plug and play charger. the look is nice and it feels good inside the ear. I was actually pleasantly surprised with the sound quality as well. Earbuds, especially wireless ones, are often dodgy in sound quality but these performed quite nicely. I would recommend to a friend who is looking for a good pair of wireless earphones.

After using them 8 times, suddenly they didn't work any more
