The Airlinks and Isports are pretty close when it comes to sound quality with a slight edge going to the Isports but neither compare to these. I did not return the product as I really like it instead I requested Amazon to give me a credit instead of returning the product. These are great ?wear all day? heel height and love the studded detail! However they are off-white and really dont match the color of the wood. If I widened the rack any further, it put the hats too close together. I wanted it for my craft supply room closet to store supplies on. The English dub is noteworthy in that both Farley Granger and Alida Vallis voices can finally be heard. I ordered a size 8 a d the fit perfectly and they atr very comfortable. Like these, will come in use to pop down the garden or in the beach I?ll eventually wear them.
