- In terms of form factor, the original sound quality is among the best. A good microphone - perhaps second only to Airpods pro. Materials of exceptional quality; everything fits perfectly.
- The main issue is that all of the most recent firmware consistently (for everyone, on all devices) broke the bass quality; the bass was only preserved in the noise reduction and transparency modes. The bass is comparable to that of the cheapest $300 headphones in normal mode.
