First and foremost I received this product to test it out and help find any quirks and problems with it, Yes I beta tested these.
These are Ankers claim to fame over their other wireless earbud iterations, the reason I say that is these are similar in design to the Apple AirPods, but they are better in every aspect IMO. These are designed to go inside your ear instead of just sitting on your ears. This creates a unique listening experience as these have passive noise cancelation due to the in ear design, The speakers have graphene drivers which aid in sound reproduction and also bass response. These headphones are IPX 5 rated, while not completely waterproof they are water resistant and for some people thats enough to get them through their workouts.
The headphones feature a 5 hour playback time that can be extended to 20 when used with the case to charge them. I personally have found these headphones to be very loud and because of that I have managed to get 8 to 10 hours of playtime out of these not including the case. The sound quality is exceptional, bass response is on point and not overpowering or overwhelming...although some may prefer more bass, but that is subjective to each opinion. The charging case took about an hour and half to fully charge and if you have ever used Apple AirPods, the case is similar in size with this case being slightly bigger but still pocketable and manageable.
The earbuds have touch controls similar to Apple AirPods, but I have found these to work a bit better and are not as finicky as the AirPods. With these you can also turn off the earbuds if you do not have the case or want to put them inside the case. I like this feature because I don't have to keep the case on me at all times, yet I can still turn them off completely if need be.
All in all if you are in the market for some truly wireless earbuds then do not hesitate to get these as you will not be disappointed. Feel free to ask any questions you may have.
