Introduction

MP4Nation is a company that produces some rather interesting cheap in-ears. Today we will be having a look at their newest model dubbed Beta Brainwavz. The MP4Nation Beta Brainwavz look pretty common, but do not let the looks fool you. These in-ears feature an 11 mm diameter driver which is huge by in-ear standards, where most in-ears use 9 mm diameter drivers. Besides the odd driver size the Betas come with a wealth of accessories compared to other cheap models. Beta Brainwavz are sold by MP4Nation and are actually supplied with several of their portable media players. They are also available separately with or without a FiiO E5 for $44.50.

Specifications

• Driver: 11mm CCAW (copper-clad aluminum wire) dynamic driver
• Impedance: 24 Ohm (+/- 20%) @ 1kHz
• Sensitivity: 110dB @ 1mW
• Frequency response: 8Hz – 28kHz
• Cable: 125cm, Y-style, 45° angled 3.5mm gold-plated plug
• Accessories: Silicon tips, foam tips, shirt clip, fishbone winder, screw-on filters

Specification wise there is nothing wrong with the Beta Brainwavz, however, they do appear to be slightly optimistic about the frequency response of the drivers, 8 Hz to 28 kHz is beyond reach for any dynamic driver at least if linearity is considered a goal.

The Package

MP4Nation's Betas ship in a neat looking black cardboard box. The box is absolutely stuffed with both essential accessories and goodies that you might find use for along the way. Besides the earphones you get a nicely padded little bag, a cable clip, two clips, a set of filters. The bundle takes after the SoundMagic earphones in the sense that they both ship with a huge bundle.


I was pleasantly surprised to see that there were a lot of tips included, however, non of them seemed to fit my particular ears that well. MP4Nation are currently updating the tips and the new bundle will provide tips with a bigger range in size and design, in order to make sure that everyone can get a good fit.


The cable quality is really good, not the least microphonic. It is better than what is on recent models from SoundMagic.
