I’ve tried Apple, tidal and Qobuz. I think Qobuz is the best bang for the buck. Offers tons of hi-res music for streaming. Even their cd quality music sounds amazing. Very large Catalog of music. The price is fair compared to tidals Mqa service and only a couple bucks more than Apple (btw just realized Apple was charging me 4$ more for subscribing through Apple Store at $17 where as from Qobuz website it’s only 13$.) And you can also purchase the hi res music from them. You can also purchase single tracks which I don’t believe other sites offer like hdtracks. And if you think you will be purchasing a lot of music they have a great Sublime plan for the year and you get even bigger discounts on purchased music that regular subscribers don’t get. I am a regular subscriber and I buy some music here n there from them.

I have the same iems and really enjoy them myself. Can I ask why you resent buying them? I have small ears so I find the smallest size they come with to be most comfortable.

I would say for details and clarity, Iems might have an edge but for soundstage probably the headphones. I went with both at $250 each haha
