  • These headphones surprised me with their sound . For the money that they cost nothing yet I have not heard better . The sound is very detailed , albeit peculiar . Lowercase very decent bass , high and sometimes slightly inflated cutting. Data highly recommend headphones for listening to heavy music genres . Also worth noting completion and a good quality of performance . Nice carrying case included . Design and usability on top. Suitable for wearing different people ( no problem with the right landing) . Good noise reduction . I highly recommend.

perfect for portable devices
  • Pronounced basses, small resistance, good mid frequencies - all this does them ideal for daily use with mobile utroystvo. The excellent design and the metal casing is important.

Really good punchy in ears
  • Before writing anything, I would like to tell you that im not a pro, but I do have a good taste of earphones. Before these, I used brainwavz m5, which I found to be very very good. But I wanted more bass which they sort of lacked a bit . When I tried these earphones, I was just amazed as these had all qualities of the M5, coupled with a powerful and punchy, but not overpowering bass ! If you love bass (not like a basshead, but still enjoy it), details and a wide soundstage, go for these, these are the best in this budget.

good headphones
  • The bass is deep and well-researched. Some formulations can be quite powerful.
    Wire - slightly thinner than the rest vntrikanalnyh Brainwavz, but it is still a twisted wire reinforced.
    Housing headphones made ​​very clean, cleaner than the previous case headphones Brainwavz. Just a pleasure to hold in your hand.

Perfect! Power!
  • Delivery was super fast.Ordered on Thursday night, Friday evening I received my M4.Box packaging kind of dent but interior was intact and good condition. Hard case is good, can well protect my IEM inside. accessories ok, was expecting to get double flanged like when i ordered my first Beta Brainwavz Pro IEM in ****(which is still in good working condition till now).

    M4 quality, i give 2 thumb ups. solid build. Without burn in, sound kind of very high for my liking. After 3 days of continuous burn in, overall sound slightly warm. Listen to Hip Hop, bass is good tight sound. Love it. Then listen to acoustic song treble extended and crisp, straight away I fall in love with it. The overall sound signature is a deep V-shaped frequency response, with lots of treble and bass. Super love it. Finally I pair up with my amp playing with FLAC. "Orgasm"!!!! Thanks mp4nation for bringing in the product, thanks Brainwavz for M4.

    This is my story.Dont know about you guys, different people have different opinion, different liking.

Great Product
  • My first purchase was the R1's and I got the M4's for the wife. She couldn't be happier with them!

    It comes with a hard case that can hold her iPod Nano plus the headphones and all the foam tips that are included in the packaging.

    She used them on our recent vacation during the flight and sound isolation was good. They were comfortable and the sound quality was more than adequate.

    Neither of us are audiophiles so it is difficult to provide an accurate description of the sound quality...but it is great for us.

Strange headphones
  • Strange headphones. The quality of performance is excellent. The cord is very good. Reliable jack. A good bag to carry your headphones. But the sound is not clear: the high frequencies strongly recessed bass bubnyaschy. Remained with the headphones HiFiMAN RE-ZERO, as they are more linear and closer to my perception of the music. BRAINWAVZ M4 or selling, or will give to someone.
