This is a really nice set of headphones - I’ve bought two pair - one for me and one for my sister. I wear them at work and need to hear folks around me. I have a pair of Bose QC 35 when it’s noisy.
The sound with these is very good, both via Bluetooth and wired. I prefer wired to save the batteries and Bluetooth when I’m moving around while on a phone call. Please note - when you are using this headphone with the 3.5 mm wire, the wire is just for sound to the headset. On my phone, I just speak into the phone.
One final recommendation - if you use this with the wire, consider buying a spare wire and remember that Bose wires are somewhat specific (3.5 mm/2.5 mm, I think). Be sure to get the right ones.
If anyone from Bose is reading this - please, please make a behind-the-neck headset.
