I think the specs got updated on the website. Its Aptx LL now.   Great, shall wait for your impression!

but i think the flaws comparing to the h7 for $100 more   1) Lack of Removable Battery  2) Non-removable ear cups (Saw in a youtube overview) 3) Lack of Aptx LL (Website). If your using Apple devices, that's fine as it has AAC.   I think these are features that one should consider the...

Is there any SQ difference between the 1st Gen and 2nd Gen H7s? Apart from the newer H7 that doesn't come with carrying pouch.

  You can check out the specs here: https://www.audio-technica.co.jp/atj/list_model.php?categoryId=1010111&sortType=releaceDate   Its sorted out by release date, the first 4 are latest ranges coming sale on Nov 25 (Japan).

  Improved Batch like 2nd Generation? The Amazon UK seems to label it as 2nd Generation H7 releasing on Nov 1.   It could be a typo. Anyway here's the link:   https://www.amazon.co.uk/Bang-Olufsen-Generation-Headphone-Bluetooth-Cocoa-Brown/dp/B01LZY73DI/   [mod edit: removed referral tag]
