I have a pair of Audeze isine 10 magnetic planar in ear headphones for sale. They were $350 new. Included is the Audeze in-ear Groovy Kit, a $50 extra, these ear tips are much more comfortable and secure compared to the originals. They are less than a year old, and are in excellent condition, with no noted issues. Rating them an 8 to be safe. I love these headphones but the exposed vents in my new place makes it impossible to enjoy open back earphones/headphones. I am the original owner.
