good enough for me

Philip.S 05.07.2020

PROs
sturdy build, real buttons, very well made

very long battery life, one of the best I've seen

Good sound quality (as an ex-audiophile, they sound the same as my old high-end audio technicas)

the app has very powerful EQ, I use it to transcribe parts in songs

reliable bluetooth, I like it
CONs:
the pads fall off sometimes for no bloody reason and I need like 20 minutes to reattach

doesn't fold backwards, as in, you can't rest it on your neck comfortably. (on the bright side, you don't like a douche, wearing headphones on your neck at all times)

the ANC hurts my ears, it normally doesn't on other headphones

Do I have a huge head or are they meant for children?

Everything they say they are - they are. But i realy don't like the tightness or the small ear covers that only my wife can wear without getting tired after 30 min. Too tight. Too small. If u adjust the head rest they just fall down. I would have bought ones that don't have noise isolation nor the cushion pads this small. But they are not as expensive as others Ill give good quality for cost.

Perfect for me.

I use these when out walking, but they have also been really useful in the studio, when combined with the bluetooth sender. Allows me to move around without worrying about cables and the sound is excellent. Noise cancellation is very good, certainly a step up from my old sony noise cancelling headphones. I would recommend these headphones.

Good in general, but a bit tight.

Quite good sound and quality. Also the ANC is very good and comparative to a set of Bose I have which are at a more than double price. The only minus is the fitting, as they are quite tight and small at the ear area. But I think that builds to the isolation factor. Also the controls are somewhat complicated to get used to, but after a while it is ok.
