Introduction

MP4Nation have made quite a name for themselves on the budget in-ear scene with the release of the their Brainwavz series in-ears. Today we will be taking a look at the newest and cheapest one in the M-series from MP4Nation. This in-ear supposedly uses the same driver as its bigger brother the M2s, but that is where the resemblance ends. The M1s are smaller and feature a less exotic design that on the flip side seems more sensible for everyday use.

Surprisingly even the M1 in-ears are fitted with MP4Nation's highly durable and well performing Ag-Cu cable that has an extra top surface coating. Priced at $39.50 these in-ears are for the more budget oriented crowd.

The Package

Like its bigger brother the Brainwavz M2, the M1s ship in a well padded cardboard box. The insides of the box are packed with foam, so you have to be incredibly unlucky to receive a damaged pair.


The bundle is really good considering that this is a set of $39.50 in-ears. You get a lot of different tips, a carrying case and a shirt clip.


Another slightly unusual feature is the 45 degree angled mini-jack. The connector should work with pretty much all players on the market today, apart from those that are deeply recessed.


With the shirt clip hooked on to the cable you can eliminate a lot of unwanted microphonic noise. The clip implementation is not as unique as that featured on iMetal earphones, but it works alright.
