I only used a few of the shelf liners ad the wont hold anything heavy but they do provide shade so this works perfect for me. Again, my custom in-ears are molded to my ears and the Bmaster in-ears are also very close to complete cancellation. Need to find uses for the extra hooks. This was a bargain but SO worth the price. I usually wear size 8, but I ordered 8 ½ after reading reviews. Other than that, Im very happy with the cover. Between these 2 issues I am simply done buying Logitech headsets; Ive had too many problems with them. It is definitely cheap! These shoes are the perfect heel height and I like the sassy leopard design. I?d definitely recommend it for someone who does normal wear and tear and is worried about drops and scratches, as this definitely protects from that and keeps the expensive AirPods safe and cute as well.
