Great product there is No cotton residue and the fact they are biodegradable is nice. I didn?t like the fact that there was no independent Bluetooth button on the car and you are totally reliant on taping the side of the headphones for everything. I love how Bert was so passionate about being Snappsys friend and I think theres most definitely a Snappsy and Bert in our lives. Excited to try these on vacation next week! I just have to lace tighter (and my orthotic helps take up some extra room). This shoes stander looks so nice and stable! So far I love this trainer, cant believe how flexible it is while wearing it even with the 25 bomes, my only complaint which isnt even a real complaint lol is that its such a good quality thick material that it doesnt make it easy to hook those latches and my arms arnt strong enough to do it up as tight as there ment to be done up, I could fit my hand under my ribs when wearing it but could barely latch it on the loosest clip. The HD 206s did not have the boom in the mid to upper bass that the other headphones did, which is a good thing. Very casual, but man its like walking on clouds. I will say that I modified mine to hold taller bottles of oil & Wirchester & such.
