Excellent noise reduction but bluetooth unreliable
- If Bluetooth worked properly I would give it 5 stars thanks to its excellent noise reduction. - Bluetooth is very unreliable at connection time, both with an iPhone and with a mac laptop. - Sometimes the headset just freezes and since the on/off button goes through a software layer, switching it off is not working. Luckily attaching USB power is enough to reset it. - The Bose app for the iPhone is simply useless.
