You dont want these sandal too short. 2 is better than the TS 2. A few years ago I purchased 33db noise cancelling foam ear plugs at my local pharmacy (three capital letters / national chain) No matter where I searched, I could never find the same comfortable, noise cancelling ear plugs. Playing music or pink noise through them continuously for several hundred hours before using them is silly. What I done was buy a small power bank EPCTEK 2600MAH for £2-96 free postage on amazon. Once a week in our house we were searching for the remote thanks to the kids losing it. Very sturdy and is exactly as described. I could readjust it or pull it away a bit but it was annoying. (1) I installed everything backwards at first and had to rebuild (2) some minor damage to wire mesh on shelves at arrival. Durable bag and zippers.
