Get this headphone if you buy an organ
I bought a Viscount Vivace from Thomann and ordered one of the T-bone headphones so I could play without annoying the neighbours!
What a lucky choice. The bass is rich and deep. Perfect for the pedal stops. The top end bright and well-defined.
I tried a Phillips and a Sennheiser and found both unsatisfactory. The Sennheisser was very good with recordings etc, but I could not hear the bass of the organ, particularly the Quintadon 32ft..
I have read some reviews that are less than complimentary, but when paried with a Viscount organ, they are great.
