I have used some excellent Sennheiser headphones for the last 15 years, but they are showing their age.
After some research, I bought a new pair of GK Ultraphones....wow....the isolation is remarkable.
I can now play my kit along with CDs (or other source) with the volume at half the level I used with the previous headphones.
My ears deserve the break.
Outstanding sound and the ultimate isolation....highly recommended....especially to anyone concerned about hearing issues.
