1 x Ethos Series MKV Premium Upgrade Cable for Sennheiser IE300

This is a wonderful cable. Flexible and soft. A world apart from the stock cable. Sound is wonderful. Null audio sent the cable to me nicely wrapped and in a reasonably short time.

Great Cable!

Really happy with this cable. Connectors are FAR superior to the stock Sennheiser connectors that ship with the IE 600. Not sure what else to write.

Great cable for an awkward IEM

I got the cable for my IE300’s which are hard to find cables for, very happy with the cable and hardware quality

Excellent Sennheiser IE600 Cable

The cable I purchased for my IE600 is truly excellent. It is soft and supple with no microphonics. I am extremely happy with the purchase and will be back to buy additional cables for other of my iems.

Christopher G. (Colorado Springs, US)
THE best IE 600 cable

Huge fan of this cable, wanted an upgrade from the 'meh' stock cable of the Sennheiser IE 600 and I am super pleased with this one. Very low memory, super soft, no microphonics and it looks amazing. Highly recommend!!

Ethos Series MKV Premium Cable

The cable is beautiful and does not tangle. There was a significant upgrade in sound quality to my IE600 compared to the budget cable I was using before. Will definitely purchase a cable again soon.
