my earbuds are from HTC, they're authentic and as a call quality vs noise, it beat soundpeats free2classic and belkin soundform play , but as for volume htc is below them , anyways i added the models in ,y thread, and i bought both of them to test out and the summary is what i listed in the thread, both are acceptable, so it's either 5.3 with fast charging , a bit louder and lower battery , or 5.1 with huge battery but without fast charging and a bit lower audio, or return both and risk with new experiment lol
