Remax RM-600M
Balanced Armature

One of the most pricy wired earphones by Remax are the RM-600M. These are quite unusual for Remax, as they don't have any dynamic drivers, rather a single BA in each side. That, however, was a red flag for me: small balanced armatures usually don't handle lower-bass very well.

Unfortunately, this is the case with these earphones as well. Although the bass is decent for relaxed contemporary music, once you enter the bassy territory, the BAs just can't handle it. Anything bellow 100Hz is missing and once you bump up the volume, the bass will distort.

These earphones are only worthwhile for their excellent transparency, but I personally don't think that they are worth their price considering their shortcomings and very limited use cases.

Pros
Cons
  • Exceptional level of clarity and detail.
  • Very comfortable to wear for prolonged sessions.
  • Poor bass reproduction. Sub-bass and lower mid-bass content is missing or distorted, especially on higher volumes. Electronic music is a no-go.
  • Slightly fat vocals because of excessive upper mid-bass and mids.
  • Overly bright because of excessive peaky treble, with noticeable sibilance and pierce.
  • Super-boring design.

Comfort & Fit

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

The lows are about enough for contemporary music, and some rock and folk. However, for more bass-oriented music styles, the lows are very poor. Everything lower than 100Hz is virtually non-existent, especially when you boost the volume up, in which case there's distortion instead.

Mids / Vocals

Although the mids sound a bit fat because of some unnecessary emphasis around lower-mids, the mids are still very crisp. Instruments sound very realistic, but vocals sound a bit honky and sibilant/hissy as a result of excessive upper-mids/lower-highs.

Highs / Treble

The treble is amazingly detailed. Every single micro-detail is transparent and accurate. This, however, comes with a price: a lot of sibilance and pierce. These earphones are hard to use on above average volumes. If you use earphones on low volume anyway, you'll surely appreciate the delicate imaging these earphones have to offer.
