For Sale:
Brainwavz M1 IEMs + CMOY Amp (OPA227) by BIOSCIENCEGEEK

Will Ship To: Continental USA (CONUS)


I'm no longer using these, so off to a new owner they go! I am selling the amp and the IEMs only as a pair, and with FREE shipping.


The CMOY amp has an OPA227 inside, and was made by the well-respected builder "Biosciencegeek". He builds these in limited quantities and sells on Ebay. This unit works perfectly and has only a few minor scratches on the outside. A nice feature is the selectable gain jumper so that the amp can be optimized for low or high impedance headphones, as well as the headphone jack which automatically turns off the amp when the plug is removed.

The M1 IEMs from Brainwavz sound very nice, and are in great condition. They come with closed cell tips and silicone tips in various sizes, and a zippered carrying case is included.


 Besides my Head-Fi feedback ratings, I have over 500 perfect feedbacks on Ebay (see username 4nradio).


Payment for the amp and IEMs is to be via PayPal, and I will ship to a PayPal verified address only. Sales only to a continental USA address only. Shipping is free!
