Seemingly good build-quality and comfortable with nice warm sound to begin with; was impressed.However, woke up on the 3rd day of using them to find the left ear channel was beginning to break up. An hour or so later and it had quit completely.Not the greatest first impression of Anker products to be honest.Sent back for refund.

There just ok sound and comfort wise but the thing that I hate is battery life I might get two workouts in then dead battery maybe I got a bad pairI guess I'll just keep looking

Requires constant charging after just a few hours use. Intermittent static when used lying down, and must be close (within 2m) to get a good quality signal. Product is just "ok" but rates poorly due to its price.

Pros:+No bouncing noise when doing cardio like other bluetooth headphones+FitCons:-Battery Life-Gets uncomfortable after a while (starts hurting the cartilage of my ears after a while)-Price

The sound quality was very poor. It sounded layered with distant vocals. I realized you can't get decent blue tooth buds for this price. I got LG's for $80 and they're much better.

Great for the first two months, but volume control is now sporadic. It's either too loud or no volume at all. I now have to unseat the earbuds while I'm working out to keep the volume from blowing out my ears. I'll be looking for a new set of headphones. Too bad, because I really liked this set.

Work great while they do. Have had headphones for a couple of weeks. Ending a work out a few days ago they shut off, and despite charging light indicating they're fully charged, I can't get the headphones to turn on.Disappointing - but when working, great product.

Kritikpunkte:- Die Akkuanzeige auf dem iPhone wandert von 100% nach 90%, 70%, dann lange nix, dann piepst es und aus ist es. Das dauert zwar insgesamt seine ca. 5h, aber man weiss ab den 70% nie, wieviel man noch hat. Hersteller hat in Kulanz Gerät getauscht, dort selber Fehler. Vermutlich daher ein Serienproblem- die Ladebuchse ist etwas ungünstig platziert

These are not worth the price you pay for them. And I'll tell you why:1. Bluetooth connectivity is a mighty pain. Juggling between Mac/Android/Windows/iOS, I've had the most problems with Windows (both 7 and 10). I need to connect it as an Audio Sink but there's also the option to connect as a "Headset". However, I almost always have to restart my device and/or the Anker earbuds (the two-button pair doesn't work) before I can get it to pair as an Audio Sink. It isn't smooth sailing with my other devices either.2. The lanyard has an overhang at the rear that prevents it from being used when you rest your head against anything (pillow, wall, etc). If you do rest your head, prepare for the earbuds to be pushed forward and render the ear-earbuds connection lose touch with your ear (results in poor audio fidelity).3. Anytime you twitch your ears the earbuds again lose fidelity due to them losing proper fit/touch with your ear canal. I realized I twitched my ears a lot after buying these earbuds. Tried both medium and small earbud sizes with no difference.4. When not having bluetooth connectivity problems, you'll discover the earbuds are out of juice. The battery life is not impressive.I contacted Anker just 1-2 days past the 30 day mark and received a 15% partial refund. I'd have been very happy to receive a full refund so I could buy a different brand/pair but they didn't seem sensitive to that fact.I've never been more unhappy with any other Anker purchase, and I own several.

Leider sind meine Kopfhörer nach circa einem Jahr defekt gewesen und wurden anstandslos ausgetauscht.Nun ist allerdings auch der Austausch-Kopfhörer nach circa 6 Monaten defekten und es gibt keinen Ersatz.Solange die Kopfhörer funktionieren liefern sie für den Preis eine ziemlich gute Leistung ab, am ehesten sind sie allerdings für ruhigen Gerätesport geeignet. Beim Joggen muss man sie etwas vom Gehörgang entfernt halten da so die Kabel-Geräusche etc. mit übertragen werden, die durch die Bewegung beim Joggen entstehen.
