Ok, so seemingly you have gone on everyones posts over the past 24 hours and stated ‘bad review’. Now you have clarified here, let me point out a few things:
Android has access to LDAC, the Q30 chipset DOES NOT have LDAC and therefore cannot make use of the (up to) 990kbps transfer rate. Just because a phone has the codec does not mean it uses it. Regarding your question about if it’s worth it based on LDAC? That’s completely dependent on what you use to listen to music. If you’re using Tidal or your own Hi Res audio files - yes if you want to abandon a cable. If you’re using a normal streaming service then regular bluetooth Codecs will cover you with the Q30s.
The Automatic On / Off was a request by users, these weren’t necessarily users who already owned the Q30s.
The Silk Drivers are a big improvement over fabric but again, if you aren’t interested in using anything but streaming services then it won’t affect you.
I’ve only watched a couple of review videos so far BUT the fact is, if you own the Q30s then you probably aren’t going to move to the Q35s. This isn’t because of price but because the Q30s are bloody good headphones already, why would you want to upgrade already.
Each to their own but jumping on every thread shouting ‘bad review’ is just going to get peoples backs up. By the way, my review (as stated) shows an improvement over the Q20s (my previous SoundCore headphones) and my Bose QC35 IIs.
