I grabbed these recently & it was my final attempt at wireless headphones - I'd heard all the hype & was offered for $300 new & I knew I could sell them for that if I didn't like them.
I have an analogy about wireless headphones - they are the audio equivalent of motion smoothing (aka 'soap opera' effect on TVs) - fortunately, these take a solid step away from that
Over the last few years, I'd tried quite a lot of pairs (really for daytime work use) including the B&W PX8 Mk 1, about a year ago (again, great price, hyped & loved the 'Iron Man' colourway).
They were super, super convenient & very comfortable - and excellent for phone calls. I'm old school (probably just old at 45) & prefer phone calls over texting, if it's someone I like, or a 10 minutes work call that cab avoid a 30 email thread.
But... music sounded absolutely awful on them. They had that horrible bloaty bass & other tuning (that can't be fixed significantly with EQ) very poor separation/imaging etc... I really tried, but they were sold on about ten days.
I got these about a month ago & I use them for music all of my working day, YouTube etc & often for watching films & series, as I find speech mix to be poorly done on so many things.
Music sounds very good. They're incomparable to my high end wired sets. Ridiculously comfy & a in
The two lessons I learned -
They don't go especially loud, and I do tend to crank it a bit... so I've learnt that I really can enjoy music at a lower volume.
Despite being enjoyable enough - when I use one of my special high sets (which Id previously use all day) - I appreciate them far more... and I think this is really important. Having a selection of the best IEMs & headphones that exist is fantastic, but all day every day - the best becomes the norm... and as good as that may sound... I'm really finding this to be a superb balance.
