Q:
The LED on my Sennheiser K6 & MKE300 only flashes momentarily. Is it broken?
 
A:
No. The LED was designed only to flash momentarily to indicate that there still is life left in the battery. If the LED were to be on all the time it would drain the battery too quickly. The battery life is rated for 150 hours of continuous use for both the K6 and the MKE300.
