If you need headphones with low latency (i. e. for playing guitar without cables) that can also be used as normal headphones for gaming, watching videos or having online meetings, then I don't think there are that many alternatives. Pros:
- Ultra long battery life
- Supports 2,4Ghz, bluetooth and cable transmission
- Low latency 2,4Ghz transmission is perfect for playing instruments without cables
- Modular, replacing broken parts will be easy
- Pretty comfortable
- Clear, neutral sound: No humming, no imbalance. Good sound quality
Cons:
- Controls are annoying: On/Off button on 2,4GHz receiver and headphones needs to be pressed for 6s to boot, 3s to shut down
- Bluetooth: Device shuts down after ~5 minutes without transmission. This can't be turned off
- The speakers are obviously wired in series - a low voltage input from my laptop or piano results in one speaker being too quiet
- Bluetooth driver issues on Windows and Linux. I haven't figured out yet how to have a conference with these headphones,. Works fine on Mac though
Overall: If you're not a musician, this is probably not for you. If you are, look forward to playing with headphones and NO CABLE MADNESS!
