Summary: refer to my Xiaomi Pistons review for my detailed thoughts about this one, this two are indentical in general. the only difference between them is the frequency balance. M4 comes with some midbass frequencies amplified a little bit which helps the naturality of the bass sounds usually, but of course that is also depends on the songs played. so if you feel distortions or overly strong bass i can suggest to lower the 125hz frequency a little bit.
Cons: Soundstage is too small, Mids are muffled, Deep bass lacks body, Treble is not seperated enough, Overall detailless sound
Summary: Brief Backstory:
I ordered the mic'd version on a whim during the brief time MP4nation had them for $28.50 on Amazon. I figured they weren't too common, and it was almost 75% off MSRP, so it was worth a shot.
On to the Review:
Out of the box, the first thing I noticed was that the cable didn't seem to be as advertised.
Pros: Deep, impactful bass without sacrificing clarity
Cons: Driver flex, inferior cable on the mic version
Summary: Build Quality, Packaging And What Have You
The packaging is typical Brainwavs fair – a black box with a window that displays the IEM. As far as accessories go, there’s the three pairs of single flange eartips in small, medium and large and a pair of Comply S400 foam tips in black, which are my personal favorite.
I’m not a fan of Comply as a company, but that’s more due to practices and not product.
Summary: I bought this in 2012-06, when my Brainwavz M2 broke. It was given a Sonic Diamond by ClieOS for the pre-order price and 4.2 / 5 for the sound quality, so I expected quite a bit.
Unfortunately, the cables are nowhere near as good as those used on the M2. The build quality of the speakers seems quite okay, though.
Compared to the M2, the bass is considerably weaker, but the higher frequencies are more detailed, albeit not much.
Pros: Sound is not terrible, CTIA plug (on the microphone version)
Cons: Flimsy cable that tangles easily, overpriced compared to other earphones
Summary: Nice product, large range of silicone cones to fit all ears. Great compatibility with iPhone 4S, the mic&remote fu,nction is really great. The mic sound quality is perfect for hands free use in you car. In one word like in more : great product for it's price Nice seller and great Amazon service, as usual.
Excerpt: Могу сказать, что за свою цену очень приличные наушники. Звук хорош и сбалансирован для (rock, ambient, trip hop), особенно после прогрева. Поначалу казалось что бас немного мешает остальным частотам, но после прогрева он стал более мягким и ощущение "забивания басом" ушло полностью. В комплекте есть мягкие вкладыши из пены, очень прикольно сидят в ушах. Их можно сминать как беруши, а потом они распрямляются и принимают форму уха.
Summary: Lo recomendaban en muchos foros y en reviews y me decidí a comprarlos. Proporcionan grandes bajos pero con un sonido muy claro, perfectos para rock. Por ahora los mejores ear phones que he tenido, venia de unos Fischer eterna.
