Very pleased with these. I had been buying the cheap single ear piece units through your typical Chinese shopping app which with postage were $15 an earpiece but after losing my last one I thought I'd check out Amazon and I'm really happy I did. These are great value for money, with postage they work out to roughly $21.50 a unit but they also come with the magnetic charging unit which can hold over 3 charges if memory serves me right. So compared to the 'cheap' Chinese shopping apps these are far better value considering the overall build and quality. I've knocked a mark off on sound quality as even though they are stereo, the stereo effect is not as wide as my wired in ear earphones. On full volume they are not lacking, with a big thumping sound though they lack a little finesse regarding musical output. Battery life for my uses hasn't been an issue so far. I've had them running for well over 2 hours without a battery low warning. The recharge box is so convenient, just pop them back in after use and they recharge very quickly. Overall highly recommended.
