I reluctantly purchased this product since it did not have any prior reviews. However this will NOT fit fat bike tires. If you use the audio jack, you get the full sound. I have had these exact same slippers ordered through Amazon last year and liked them so much that I reordered them again by looking them up under previous orders, I wear these all day for most of the day and they are a comfortable from day one until its time for another pair! The skys limit when it comes to headphones, and its a hugely subjective choice, though of course there are specs that matter- frequency response (the range of sounds it can accurately reproduce), Impedance (higher impedance will sound cleaner, but require an amp) and so on. I really wish it would have worked, it was exactly what I was looking for. Clip/carabiner/hook has been redesigned, more usable in my opinion. ) as well as earbuds volume level. They are super comfy and fit well! I had high hopes for these for the summer as their slippers and trainers have helped in overcoming plantar fasciitis but they have failed with these sandals.
