Hi I recently purchased Audeze iSine 20. I really love its sound signature but I am having issues regarding comfort with them. I tend to have discomfort after wearing them with ear loops for couple of hours. Also the attached wire effects portability and makes commute bit of an issue. I would really like some recommendations regarding truly wireless headphones/iem with similar sound signature, preferably iems. I am willing to spend anywhere between 500-800 dollars.
