Ive included pictures and measurements that show clear difference between the sandals. Previously, I had the Astro Mixamp and Soundblaster ZXr 5. The website wouldn’t allow me to submit the claim. When that moment to listen to great source material arrives and stunning replication of detail, tone and total immersion is required, the Beyer DT 880 headphones deliver. To be fair, Im not sure if these (software) failures are because Im using it with WIN10, if its because Im using it with wireless headphones, or if thats normal for the adapter itself. I wished I’d found this brand back in the spring, because their sandals are adorable. Good earphones. Some sandals require a bit of a "break in" period but these definitely do not. And also helps me sleep at night, keeping out the sound snoring hubby. I actually like that it doesnt have those seat-tube stabilizers as they always just got in the way when taking my bikes off and on with previous racks.
