Review on Ururtm Headphones Comfortable Meditation Relaxation Headphones by Boss Spangler

I bought 3 of these - the first one was so comfortable I ordered 2 more. The 2nd sound was only in one ear. The third stopped playing in one ear after 1 month. Tried to contact the company for support (to avoid going back to Revain) but no response. I'll just write this off as an unresponsive company but wanted to warn others. Maybe there are better sleep phones out there. Update: The company contacted me and quickly rectified the situation by replacing the phone. Substitutes work well.
