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.

Incredible sound quality but too delicate.
  • Having gifted my PL21s to friend I decided to try for something new and better. Thankfully just around that time the awesome M4+Delta offer was on so I typed in my paypal details and got these.

    First impressions : Great packaging. Like many earphones this came with a bunch of tips (including comfy foamy ones) but I really like the box and sturdy carry box given with it. The earphones were disappointing. They seemed far worse than my PL21 and I almost felt cheated for a second.

    Then they opened up and it sounded like heaven. It took a week or two but it sounded fantastic. I was hearing notes and instruments I hadn't heard earlier and all from my Nokia phone and no fancy mp3 player. It was quite literally heaven. I literally loaded up my Nokia with new music just to hear it all again. The clarity was outstanding and the bass was comfortable and roomy. Furthermore the earphones even had nice amping so when I switched to an Xperia phone which had a lower sound output, they were still quite loud.

    Then the right side earphone gave trouble. FML. After a quick talk to MP4 nation people I destroyed my first pair and got a replacement. The replacement again took 2 weeks to open up but it sounded great and I was really happy.

    However, two weeks into a year and then the left side gave way. Sadly, mp4nation customer care this time refused to send a replacement and instead asked me to mail it back to them in Honk Kong so they could check it personally. Yeah, no chance of me wasting money doing that.

    It was fun while it lasted. I wished it did last longer but oh well. On to a better earphone.

    Full disclosure:
    Bought on : October, 2013.
    1st set died : December 2013.
    Replacement arrived : January 2014.
    2nd set died : Novemeber 2014.

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.

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.

Decent earphones with amazing bang for the buck
  • I immediately loved how well these little beasts sound. I'd say highs are a bit recessed, but at still a decent level - you can't ask more from a product of this price level.

    Mids are nicely underlined - not "in your face style", in a good way. Bass is awesome.

    I also loved the hard case which came with the buds, looks great and is comfortable. I also had no problems with the cable in the mic version.

    If you're looking for something decent under $100 these things really deserve to be looked at.

Good earphone
  • Just received my M4. Very strong beat, which is what I like, and the sound is clear. Quite good earphone for this price.

Good headphones
  • Good headphone, built with solid material. Very clean sound in the highs, mids and excellent basses. The microphone has a good sound quality and is very functional. This are my first Brainwavz and I am very satisfied with the purchase. Five stars deserve.

Good but low build quality
  • I brought these after reading after lot of reviews. and I really enjoyed my 1st year. But just after 1st year which is 3 months back. My left speaker isn't working. and the warranty is gone and no service center in India at all. and if you plan to buy these buy the one with no mic which has better built quality. I am not sure if I can blame them or not But I now have broken piece just after my one year completion.
