I have been using the Hesh 2 wireless headphones for months now and I have not had a single issue with them. They hit every possible request you could ask for. Starting off the sound quality is great for the price. The headphones have great range of treble and bass and volume limit is decently high. On top of the sound quality the battery life on these things are ridiculously long! They say on their website up to 15 hours of listening and damn they are not lying. And even if you were to forget to charge them and they died on you mid trip, you can just plug in the provided auxiliary cord and have them hardwired into your listening device. The headphones have a built-in microphone so you can use voice command and also take phone calls!
