I am just a simple user, but I send them back very fast. I think the hype is marketing. Main issues I faced:
- Super flat and low bass out of the box audio. Very bad sound.
- Requires a LOT of equalizing to make it sound OK, but the software is not user friendly, so very frustrating process. You can't edit a saved profile for example.
- Buds are top heavy and bulky so near impossible to get them to fit and even if you do, they slide out in time having a HUGE impact on audio.
- BT connection unstable (many drops) while my old Sennheisers TWS 2 have 0 drops.
WIth these issues even good measurements would not convince me.
