I have the Sennheiser 598, Bose QuietComfort 25, Bohm, many Sony MDR line, to name a few. I used it for the first time couple days ago, and it worked as expected. The convenience on my desk and nightstand is great, and it charged my phone 15% in the time it took to write this review. To show the difference, I use both CAT-6 and CAT-7 Ethernet cables. Im looking forward to playing brick. I preferred them, even over headphones that cost twice as much. Comparing it to the old set, that was immediately confirmed. The perfect addition to my closet remodel! Well as you can see from the picture, theyre still somewhat too small. If I had to give you the sound barrier quality in terms of numbers, if bose is 90%, after the swap its like 50%.
