Bests & Worsts Reviews from Amazon

I am a headphone guru, I have owned the following, from time to time: Sennheiser HD 800, 650, 600, AKG K701, K702, Grado RS-1, 325, BeyerDynamic T1, T50, 880 Pro 600ohm, 990, Bose QC20, 25, 30, 35, Wireless Sports, Jaybird X1, X2, and other many AKG/Audio Technica earbuds. So you can take a reference my experiences :) Conclusion of Anker Sound Buds: - Wearing comfort: 9 out of 10, VERY comfortable and fit into the ear deeply and tightly - Sound Quality: 8 out of 10, comparative to earbuds up to $149 USD. Too much bass for me, clear and comfortable mid and high - Playback time: 10 out of 10, haven't seen a known brand has >12hrs playtime earbuds. Probably Anker knows better how to maximize battery power usage by design - Noise reduction: I am not familiar with CVC, but it doesn't seem to be an active noise cancellation like my Bose Q series, which you would notice an obvious switch when coming to NR on/off. It's about 6~70% noise reduction power of comparing to Bose QC30. Summary: 9 out of 10. I would highly recommend this earbuds to ANYONE who is looking for a budgeted, long play time blue tooth earbuds, which sound quality matters at any kind (preferably pop music, as the bass is a bit too much comparing to other earbuds / headphones). Given the price, it's a no brainier pick.
