I just bought a set of Sennheiser HME110 for using in C152 / C172, was suggested to me as they are a little more comfortable than the DC headset.
I intensively researched both before I purchased mine, and different reviews different results, but the DC10-13.4 & the Sennheiser HME 110 rank 1st and 2nd almost everytime.
There are a lot of posts here about headsets, so maybe have a look through and PM someone who has recently purchased one.
Hope this helps, and not just me ranting on cause I bought a headset recently.
