Sony NW-WM1A Listening Tests In high mode using balanced output, I was pleasantly surprised that there was enough power to drive my inefficient Ether CX 25 ohm headphones. The sound was very clean and detailed with good bass. Switching to Sennheiser HD-650 in low gain mode was disappointing. There was no dynamics and bass was suffering.. Sony Support NW-WM1A.
