And some final (for now at least

) findings on the Free Byrd:
- They don't have multipoint but at least switching between previously paired devices is easy. Just press connect on the new device - that's it. It will disconnect from the active device and connect to the other one directly.
- The audio personalization seems to only work on the device(s) where the app is installed. When I switched over to my MacBook, they sounded "normal" again.
- I was walking around town a little bit with them today and they handled wind very well. It does not get amplified or anything when the Free Byrds are in ANC mode. There is no specific wind noise reduction feature, but they don't seem to need it anyway.
- ANC is mediocre outside. I could still hear cars passing by quite easily. So they are no ANC king contenders.
- Transparency mode is also just average. Nowhere near as good as AirPods Pro or even MTW3 level.
- Had some more calls with them. They work very well, even outside. No problems there.
- Battery runtime
is officially great. They do charge slowly though, at least when they are completely empty (3:45h if case and both buds are depleted, which rarely happens, I guess, but still).
- USB-C port is at the back of the case where it belongs (Hi Sennheiser!)
- Fit is still very comfortable and stable especially. Could be problematic for small ears, though.
- Sound quality is pretty great still as well. I wouldn't say they are better than the EX as the tuning alone is so different. The EX are more "beautiful", "relaxed", "melodical", and "confident" sounding, if that makes any sense. The Free Byrds are more "in your face", "bassy"and "forward" sounding. I would still say that the mids are taken back a bit while the upper mids and highs are more prominent. That can be a little fatiguing on loud volume levels with some recordings but they are a lot of fun and still have a great soundstage, great instrument separation and positioning. It feels a bit 3-dimensional at times, especially with the sound personalization turned on. And, again, they can get incredibly loud.
- The Bluetooth connection so far has really been rock solid. Have not yet experienced one hiccup or dropout yet. Range is very good as well. They did well on my usual Bluetooth range test, better than the MTW3 and the EX.
All things considered, this really is a very solid first TWS from Beyerdynamic at a fair an reasonable price point. The downsides remain the size of the buds and no multipoint support yet (however many brands seem to implement that via firmware these days later down the road, so maybe Beyer will as well), as well as no user customizable touch controls (I would change "next track" to two taps instead of toggling ANC with that e.g.) but controls do work well generally. That and the music doesn't pause when toggling transparency mode (like on the MTW3 e.g.).
ANC and transparency mode remain in the neutral part of the "review". Both could definitely be better.
And on the plus side of things we have: sound quality with sound personalization, battery life, fit, volume, call quality, bluetooth connection/and a huge variety of tips.
