Any comparisons er2se/xr vs mk5 ?

I tried 1p2 and didn't like them. Sound is "synthetic", imo. Nothing like true timbre of 335DW.

Hi all!   Please advise a dynamic iem with similar sound in terms of quality and character as in 335DW. Price doesn't matter.

Any hissing with AKs? Which one is better with 335DW? 100 or 120? As I know the 100 has output impedance of 22 ohm and it will make 335DW sound a little bit brighter and maybe refined that's rather good. Is that true?   I'm not in Japan. Thanks for the information. If this upgrade is not...

Hi all!   Please advice best portable player for 335DW. I don't mean the most expensive on the market. I need something really portable but with good synergy with 335DW. The price doesn't matter but I always prefer reasonable options, not the priciest. I'd like to read recommendations from...
