hi, excellent review, do you think that for the price it is better soundstage than you can get? Or do you recommend some other model with a bigger and more detailed sound? for that price I could get a se535 but I do not know if it is the best option.

Thank you! The MGS-401 has good soundstage but it is light in bass. It depends on other factors you are looking at too. There are other recommendations that has good soundstage too but they offer other aspects. Tansio Mirai TSMR 3 for 7 different sound signatures. TFZ Secret Garden HD for impactful bass.
Cheers & Happy New Year ahead!

Big fan of your site and reviews here, love how your analyses are concise and straight to the point. I know they are in total different price levels, but both being 4 driver IEMs, can you please compare the MGS-401 with the IT04 in terms of transparency, detail retrieval, overall FR and isolation? Thanks a lot in advance!
