Bests & Worsts Reviews from Amazon

Only because I bought the previous version and it worked great... then a few months down the line it went out on me. Replaced it through warranty and it worked great for a few weeks and went out on me. Replaced it again and it worked great, then went out on me in a few weeks. I had to get a refund, which allowed me to buy this one, but I had to pay the difference because Anker would not upgrade me, even after all the problems I had with their previous version which I about in Oct 2017. Problems started in Jan/Feb till I replaced it with this one. We'll see how this experience is. UPDATE 5/29/18 Since posting this, Anker customer service offered to send me the Anker SoundCore Boost speaker for all my trouble. Not only did it come timely, but that speaker is really impressive. The sound was clear, with umph, and bass boost that you could really feel. I appreciate them going out of their way to make this situation right. The Soundcore Spirit X Sports Earphones have been regularly used and are so far are working great. The Anker SoundCore Boost speaker they sent is icing on the cake. UPDATE 6/3 Since posting previous update on 5/31 while running on the treadmill the headphone on the right began a static scratchy noise that was so bad I had to take it out of my ear. The left side continued to function, but had echos or had faint sounds like it was about to do the same. I shut it off, waited and tried to turn them on. The same right side problem, but left was ok. I continued using only the left side while running and then after close to 10 minutes the whole thing shut off. Initially, I thought, maybe the battery was going out and it needed to be charged. I left it charged at home and came back to it a few days later and the red light was still on (meaning it was charging). I disconnected it and tried to turn it on and got nothing. Basically, this lasted less than a week and I was told this was the newest latest model and it SweatGuard Unrivaled Sweat-Proofing with 12 hour playtime. I wish I didn't have to type all this, but I'm upset and disappointed. I just did not live up to the advertised billing. Looking for a refund or replacement (yes I would even try to replace it once, even after all this, but after that, no more). Update 7/3 Since post, I received a replacement again from Anker. It is working so far and it charges. Let you know if anything changes. Last update (7/8/2018) because I'm DONE with this product. Shortly after posting on 7/3, the earphones shorted like they did on 6/3. This time the static sound was heard on both earbuds and then the left ear went out, while the right ear continued working. Upon arriving at home, I tried to plug it in to charge it and no red or blue light came on. I can't turn it on anymore... again. I want a FULL REFUND. Anker makes great other products (i.e. wall chargers, strip outlet chargers, battery/wall charger and speakers), BUT this Soundcore Spirit X Sports Earphones and the prior model before this one (you can read my review and troubles on that one too) IS NOT A PRODUCT YOU WANT TO INVEST IN. And I'm actually sorry to have to say it. Everything recorded here is accurate and true as it happened.
