I wish comply would have a intro package with one of t, ts, and sx for new users to try them all out and see which is mosy preferable. Amounts of improvement. Such a fantastic upgrade from stock silicone covers.

Comply ones are durable and last a long time. My only gripe is with how quickly they wear out. A mixed size pack would be a better idea when just getting started.

The tips fit on the earphones perfectly with no concern for slippage in the near future. Noise attenuation is excellent with a slight hint of warmth added to the sound compared to silicon tips.

Even with audiobooks, the dampening effect on outside noise can't be downplayed. Way more bass and louder.

Used these on my wooduo 2, fischer audio eterna (bass heavy earphones for house music) works well with my audiofly af56's. Works for my x3 jaybirds. Have to use a bit of elbow grease to work them onto the buds initially.

One of the foams deteriorated less than two weeks of usage. If you wear them for a long session and the foam gets too warm it literally falls apart and bits fall off in small and large chunks. They certainly don't get the job done; they crumble.
