The Package & Closer Examination »

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.
