People buy $2k cables saying they hear a difference. Listen to whatever music service works for you. Care about artist payout? Find a service with a higher payout. Care about really good discoverability? Spotify's algorithm for finding similar music to what you like is, imo, miles ahead of any other service.

Personally I have a DAP for listening to music on the go or in my car and when I'm at home I use foobar, but the convenience of any music service is also great.

I don't think so, it's mad overpriced unfortunately

The headband itself is only a bit lighter than the stock one but it's much better built and designed. To me, it's a lot more comfortable for long sessions and the weight seems to be distributed a lot better.

It's expensive but to me was well worth it.

LCD-X + the carbon fiber headband is great.

Some may not like the sound without EQ, which is understandable, but imo these take to EQ extremely well.
