I play them balanced of the EarStudio ES100 which has an excellent eq function, and the Blon responds magnificently to such adjustments, allowing one to tailor a V shaped profile if desired with minimal distortion. Sonys XM4 headphones, along with the AirPods Max and Bose 700, have amazing noise cancelling. This was just what we needed for our laundry room to hang clothes right out of the dryer. Entweder man mag die Schuhe oder eben nicht. I bought these last winter and one of them started ripping out and bottoms coming off within a month or two. IT IS NOT PHYSICALLY POSSIBLE TO WEAR THROUGH THE SOLE ANYMORE, (Rendering their 5000 mile warranty moot) as the sole will separate from the upper long before that. I kept loosening and tightening until it began turning smoothly. However it is important to note that these are only for the bikes with tiny wheels such as the balance bikes. I do not like very thick and bouncy soles on my flip flops and I do not like arch support because I have high arches. I removed the velcro and used hose clamps to secure them to my bike frame and front shock.
