"My only gripe is that the product wasn't exactly as the pictures on mp4nation. I think it would be best to update those.

Otherwise the shipping was quick and the beta+ iems sound great."

"very good seller.BRAINWAVZ Earphones liked.Packing an excellent"

"Fast shipping and all items are very qualified."

"Very fast shipping! Price is very good! Product is ok!"

"Cheap price and wide range of high quality products. I purchased a Brainwavz M2 and they threw in a Fiio E6 for free which is fantastic. Shipping to Australia took about 2 weeks but the wait is worth it."

"Great merchant - shipping was fast, product properly packaged - nothing to complain about! Free headphones are a nice bonus"

"Great service, the fastest delivery so far in Siberia and unbelievable product quality."

"yes i received brainwavz beta v2 today after 13 days, received with perfect packaging and zero damage thanks to the Mp4nation.

my first impression when i play is boomy bass, sound stage seems to be wider and impressive.the only thing to my worry is details with poor highs(it lacks real treble to my likings)and can hear sibilance in some tracks but its not a big deal for me. the clarity seems to be very good, no problem there but still details, treble, clarity seems to be lacking when compared to the stock earbuds from cowon e2 which is why i bought this beta's for replacement.the stock earbud which i want to replace seems to be more airy and open sounding with loads of treble which is why dissapointed. other than that, its good with bass, impressive sound stage and feel non fatiguing

Pros:
1.impressive soundstage,
2.bass(with quality),
3.superb lows and good mids

cons:
1.poor highs(no treble to my taste),
2.not a detailed one(for the price range , u cant expect to be analytical type like RE0)
3.sibilant sometime but its not of great deal"

"Very satisfied customer over here. Great customer service, fast delivery and of course the most important part: great product. I got the entry line Brainwavz Beta iems at special easter discount, and really for the money, I am blown away by the sound quality.. the only thing I would like to have seen included is a carrying pouch, but again, for the money I don't really think it is reasonable to ask for anything else..(they even come with the excelent comply foam tips). When I consider replacing or upgrading my iems, MP4Nation and Brainwavz will be on the top of my list.

"Purchased a set of Brainwavz M4 IEM off this site. Great value! Got them for 50% off with free shipping to Canada. Used Facebook coupon for even additional value.

Product exactly as described, shipping took time coming from Hong Kong, but arrived well packaged and complete.

Love shopping with them, would do it again! Thanks!"

"Low price, fast shipment. Great support via mail communication.

I really recommend this e-shop!"

"Great Now i am enjoying this fantastic IEM"

"I ordered a few earphones from MP4 Nation over a couple of years from and products arrived as expected. The Brainwavz Beta,M2 and M4 are all awesome ear buds and are worth the money. If you are a bass lover you should go for the M2 as i am now listening to the M4 and miss the bass of the M2. The M4 is more clear and detailed and is good for vocals and instrumentals."

"I have now purchased three Android tablets from MP4Nation and have been extremely happy with prompt delivery. Good correspondence when required and would recommend using the site."
