Advanced M4 review

Whats in the box?






The M4 earphones and a hard shell carrying case.


A healthy selection of tips is supplied





M4 with splitter visible


M4 inline remote


M4 shirt clip.



Build


The metal earphones themselves seem fairly robust as would be expected.



Strain relief at the earphones shell seems strong.



The cable itself is twisted (not braided) and resembles a custom cable style slightly.
Cable seems supple enough, although quite hard.
Mine had kinks in it due to the way it was packaged, but started to even out after a bit. 
(Better to coil the cables in a circle, rather than with a tie in the middle).



Gold plated jack.
Below is a hard rubber splitter, the type we see on many cables. seems sturdy.
No neck/chin slider though.



A simple inline microphone for answering phone calls etc.

The frequency seems different on innerfidelity and veers more towards the bassy side of things,

Innerfidelity measurements



 Sound 

I tested the M4 after 100 hours of burn in.

I used the Opus#1 Dap in my listening, FLAC tracks.

The Advanced M4 is a sub $100 earphone which comes across as an airy and pleasant earphone, has enough bass to satisfy. It can go quite deep on some tracks.

The sound stage is medium, which seems larger due to the highs and the exquisite instrument separation.

Vocals are centered within the front of ones skull and are generally smooth and well defined.

Good height, medium width.

Still confused as to why the frequency charts are so different.

 Value

At around US$40 -$100 ($40 0n their website) the M4 comes in at the sub $100 bracket.
Many earphones of varying quality reside within this price range.

It seems of good value with a clear sound, good detail and a wide range.




Overall

The M4 is an earphone which would suit commuters on the go.
Its low price and sturdy cable useful in such situations, its online microphone handy for answering calls on the move.

Easy fit and insertion and a wide range of tips to choose from.

The graph shows a bass roll off, but this isn`t terribly noticeable, and is more in the sub bass region.
When in fact I suspect this earphone is more in line with innerfidelitys tests which make it a more bassy earphone, with a slight v shape towards the upper mids.
But it is a bit difficult to pinpoint whilst listening which is the more accurate frequency table - although I would generally go for innerfidelity and their track record.

As the price on their website shows it marked down to $40 from $100 it begs the question. 
Is this a $40 dollar earphone or a $100 one?

Many have remarked online that the M4 resembles an earlier earphone Wi-Micro (US$189-$284), Advanced have assured me they are different earphones with a different shape, price and specifications.

Having a clear sound, with decent clarity and a slight v shape they are easy to listen to.

As it stands the unit I have has great detail retrieval, smooth sound, easy highs, enough bass to satisfy - (but it is not a bassy earphone as such), decent sound stage and a generally fast response with and overall airiness.




 Thank you to Advanced for sending us the M4 for review
