SpinFit CP240-L - Double-Flange Silicone Eartips Replacement for Universal IEM Earphones with 5 Inserts - 1 Pair - 4mm/2mm Nozzle Diameter (Large)

My ear canal turns into a slip-and-slide when I'm exercising and until now I've constantly been shoving my wireless earbuds back in as they slowly slide out. It's been a frustrating distraction during exercise I almost gave up on earbuds and was going to buy a pair of over-ear-phones.These spinfit earbuds have changed all of that. They stay in place even during the sweatiest workout. I get a great seal and deep bass with no sliding out.They're expensive but worth it. They come in 3 sizes. The L worked for me, I'm a fairly big guy.

Initial impressions: Love em. They fit my Andro’s & insert/seal well. They may cause me discomfort over time. I have spent a small fortune or Comply/spinfits/spiral dots/silicon & ear impressions in the past.edit: Great idea but the silicone sits so deep in the ear canal it causes irritation. Even used olive oil to help but didn't help. Now in box with other spare tips. Strangely I don’t get this itch with Etymotic triple flange

Best ear buds that I have tried.

I ordered these as SpinFit TwinBlade double-layer ear tip replacements for my NuForce BE Sport 3 wireless earphones, but despite ordering large size, nozzle is not big enough to fit.....these were the largest size I could find, & I cannot find what I want/need anywhere.

Too expensive and they still coming off my ears wasting of money I would t recommend them at all !
