I’ve just bought a pair of Sennheiser Momentum 2.0s and I am currently having a love affair with all my favourite albums, hearing details I’ve never heard (and just enjoying their impressive soundstage). They cost about £400 (about £100 of that is for the wireless/noise cancelling functionality). Not exactly audiophile level but probably the last headphones I’ll buy for a long time.
I’m kinda mid-level snobbish about this stuff - do all my out-loud listening through various bits of Sonos kit which are fine enough for me (especially in 5.1/stereo pairs).
I can’t really tell the difference between FLACs and high-quality MP3s, but I do have a bugbear about anything below 256. I get sent lots of albums to review, and it’s all done digitally now. So many albums get sent out as 190kbps streams/downloads , which I think is nuts. Horrible compression artifacts all over the shop. You’re asking people to review your client’s album, without letting them hear what it actually sounds like.
