I bought these new in June of 2025 for $521.27, but in the time I have had them I have hardly used them. They come with the original box and matching serial number so you know they are legit and not a fake knockoff (very common, just look on Reddit!). They sound fantastic and have great noise reduction, spatial audio, head tracking, audiogram capability, etc.,
These are the later generation with USB C that allow connection to computer for lossless audio listening. This is the upgraded first version (from lightning cable) I'd call it Gen 1.5 (!) From what I can tell the differences are marginal between these and the current Gen 2 model, but you can read lots of reviews about the relatively minimal changes, none affecting sound or headphone use.
Besides the headphones, USB charging cable, 'Smart Case' and the original box, I'm also including the Silicone covers for the earpieces, and headband which I have had on them since I bought them. The pictures show the headphones with and without the silicone covers. They are essentially as new, and as they say, "my loss is your gain".
Since I wear hearing aids, I wanted to use these putting them over my ears with the hearing aids on, like I do with my Sennneheiser 660S phones, but the ear cups are not large enough for my old big ears to comfortably accommadate that. I finally decided to let these go!
Lots of words above, but hopefully you got this far. All the usual seller 'notes' apply - if the ad is up it is still for sale. If you sound like a bot, I will ignore the request. Chat works really well if you have never used it (you need an account) If you use email or text, please at least try and sound human (e.g. give me something - your part of town, your name, and/or use my name (Andy) when addressing me, and at least let me know somehow that you read the ad and know what this is..
