# M2 AEBT - Wired + Foam Spacers Modification

Detail and treble are both lacking.\
\
The pads on these headphones get flat quickly after a couple years of use. This is proven by my previous graphs of the same headphone without foam spacers in the pads. \
Measurements in different positions were wildly erratic and inconsistent.  

Now, with spacers, channel matching and measurement continuity are vastly improved. 

I recommend everyone who owns one of these to add foam spacers inside the ear pads... and boost treble with EQ.
