Shure EATFL1-6

I would not use any other than these for shure head-phones and for everyday use (loud work space, airplanes) but the durability is a bit disappointing. After a while they sort of start losing their adequate shape for isolating correctly. I use them everyday at work and go through 3 pairs like these in a year at least. Their a bit too expensive for buying large quantities, otherwise it would have been fine. I only find them at thomann so I make sure to order 1-3 sets each time i make an order. They are also not super isolating. They're perfect unless it gets super loud or really loud for a long time. If some things get super loud at work I put proper ear protection over my head phones while it's lasts. I guess there are even less durable and less practical sleeves that handles that really loud stuff better.
