Very Good IEM
  • this is my 1st brainwavz IEM. i bought for $26 (thanks for the coupon) last May. The sound production is very good. Most of the my friends never heard of the Brainwavz, all of the amazed how good the sound reproduction is. Most of the time it was with my friends. The seal is very good. most of the outside noises wont come inside. really love this Headset. I will definitely buy more brainwavz headsets.

best headphones
  • Depending on the price, very good quality and balanced sound. I would recommend.
    -Cons: Cable thin, a little heavy on the headset parts, rubber insulation is poor.
    But the sound quality is very good.

Good sound but the build quality could be better
  • My first pair of M4s started having problems after a couple of months. The cable had technical difficulties and after some time I could not hear anything out of the right earphone. So I returned them to mp4nation and got a new pair. The second pair lasted a bit over six months. This time the left earphone broke so that the left earphone's cable wiggles a little out of the housing. The rubbers that come out of the housings also broke and are now hanging down the cables.
    The sound quality is good for the price. The bass is boomy and quite nice. Classical music does not sound very good on them because of the bass and lows are booming. The highs are slightly lacking and the mids, for example guitars, are quite crisp.
    Design 4/5
    Build quality 2/5
    Sound 4/5

Fantastic earphones
  • The bass is well balanced but the treble and vocals seemed to be a little bit owerpowering on my ipod touch 5th gen.But you know ipods they have a crappy eq so its almost impossible to get a good balance when you need.So I blame the ipod on that one.The vocals on this one is just unmatchable and unbeatable I have used a pair of jays and they are well above as far as the price range goes but these m4 pairs are in par with them.So cheaper but same vocal deepness.Another thing is the sound stage,you can hear and differentiate each instrument and you can clearly visualize the placement of each instrument at the time of the record.So another plus and thumbs up on that one too.

Maybe better then M5
  • If you have to decice between M4 and M5, just go for both and compare them 1:1. Just a question of personal preferences soundwise if you ask me. Highly recommended anyway

  • im using R1's but i compared R1 with my friend's M4 and i can clearly say that M4 has more natural sound than the R1. and build quality is impressive.

click for full-size image
Great sound but button sucks!
  • These have great sound for the price, particularly after burn in. However, the button is practically useless. It is really difficult to click properly, eg click three times and it stops the track instead of going back one. This means I have to click it about 10 times to go back a track. The clicking is also really loud, people on the train think I am trying to send morse code.

    These would be perfect headphones if the button was not a ye olde telegraph morse code button. They would be great if it was a soft button with volume like those found on apple and logitech headphones.

Solid bass and V-shaped
  • The M4 is a good performer for electronic and acoustic music. It has a strong well defined bass, quite laid back mids and smooth clear treble. The only disadvantage is moderately high price, but promotions and sales can make it very profitable.
