The Sennheiser m@h40 is one of my oldest headphones i still use.

Have  been bought   about 6 years ago (i do not remember very clearly but I think it was on 93-4 ), little after i think the Koss 20 for only multimedia usage, ie for computer and mp3 players,   as  advertised. What impressed me very much was their very low price ,  about Eu6   for the at time as afar as i remember . Found and their dealer i Greece Nakas , a national seller of musical instruments and audio equipment . and official dealer of Yamaha audio.

Another impressive with this  is their production : Ireland !


The m@h40 is one of he most lightweight earphones i eve had switch just a  plastic cover that is ca 1.5 mm  thick and  movable heads over an axe/horn of 10 cm of length  and ca 2 m  of cable length using a linear mode plug of 1.9 mm




Its headphones  are open type full ear flat and have a relatively thick ear pad for touching to ear.



As from the side of audio it is a little peculiar

1. Its audio volume level  is generally  quite lower than the mini earphones. you need  to add some 5-6 db of  volume  in order to have the same audio with other mini ears . Audio volume level is close to the most open type  headphones

2. It has  more trebles  than  most earphones of those times , lacks some bass and mid tones are slightly lower . Tha means the trebles in result go higher ...

Using  on computer  and testing with the AKG K66 its audio seems bass up-shifting with little more trebles and  less richer audio and about 1 db lower audio!  . Not to mention that K66  is still relatively  trebly !

All the above  make this  headphones being not 100% compatible  for mp3  computer listening, unless  their treble quality is low  . In contrast after my older Phillips mini headphones used for  SW listening have been  destroyed , this is my best for usage in shortwaves , as it has its audio fitted for the R75 !

Using on R75  it seems  needing  some more attenuation . Fortunately i have a plug-in attenuator from anm Aiwa Walkman  of the older times  (2000) that can lower audio from R75  up to 35 db

And from  ca  2 years on , this is my most used ears.together with the  K66  from Koss  (these Koss 66  are used for computer )
