The Remax brand was highly recommended to me. I've got to say that I'm impressed! These tiny earphones sound absolutely amazing. The bass is punchy and quick, and fills the mids with warmth. The mids and highs are among the most vivid and accurate you can get! They are very detailed, bright, yet warm and exciting at the same time. The main issue with these earphones is, like with many other micro-driver earphones, that their maximum loudness is slightly lower than usual.
These tiny earphones are very easy to fit into the ears both using the M or the L tips. They are very light, thus stay firmly inside and offer great comfort. You will literally forget that you have these earphones inserted.
Lows / Bass
Fast and quite deep bass. The sub-bass is definitely there, and while the lows are slightly shallower than what you get with Joyroom JR-E103, it's actually more controlled, quick and precise as well. Very enjoyable, even for electronic dance music. They are, however, overpowered by the sharp highs and lack any exciting impact.
Mids / Vocals
Great and bright mids. Warm, detailed and surrounding, and unlike Joyroom JR-E103, they are not recessed too much. These are great for vocal-oriented music genres and even especially good for metal music, but tonally they sound a bit cold and unexciting.
Highs / Treble
The highs are sharp and emphasized, not as piercing as of Joyroom JR-E107, but also brighter and more pronounced than of Joyroom JR-E103. The tonality is very similar to that of Joyroom JR-E107 - bright and quite detailed highs.
