Comply P-Ser LG-BLK 3pr P-Series Earphone Tips, Black

Isolates well if you insert it into your ears properly. Will buy again if needed.

Isolation et confort maximal !

non voglio entrare nel merito del suono, se trovate benefici con i tips in foam, questa marca è l' unica che ti propone un prodotto di qualità, il foam ò durevole e soprattutto ha un ottimo "ritardo" memory ,a differenza di altri che appena li schiacci ritornano immediatamente nella forma originale, impedendo di fatto la buona inserzione nell' orecchio

Memory foam di buona qualità ma tende a separarsi dal supporto in gomma rigida per connetterlo all'auricolare.

I recently bought Etymotic's excellent ER2XR and have been really enjoying them. I don't mind their notorious triple flange tips but I don't always get a great fit and often have to reposition them. I tried the included foam tips and found I got a more consistent fit and did not need to adjust them. They aren't the most comfortable though and they don't look like they would last long. I looked for a third party tip and found the Comply Professional series, I have had good experiences with Comply products. Once fitted to the sound tube on the Etymotic the foam protrudes past the end of the nozzle, this is a good thing as if the nozzle is too widely exposed in the ear canal it can lead to the micro filters on the earphones getting clogged, even if you have very clean ears. I have first hand experience of this, you may notice that Etymotic eartips including the foams have a tiny aperture at the very end rather than a wide bore, this may be for purely sonic reasons but it also prevents ingress of ear wax and other debris clogging up your earphones. As with most foam tips you squeeze and roll them with your fingers to make them easier to insert. Put them in as far as they can go without force and gently hold them in place for about 15 seconds as the foam expands to fill your ear canal to form an optimal fit, there is nothing else you need to do. I can wear mine for many hours with no discomfort. They feel so much more comfortable than the original Etymotic foams, those are more like a sponge and a little abrasive. With some foam tips on more conventional IEMs sound can be altered by them, bass usually increases in quantity but not necessarily in quality. With these foam tips and this Etymotic earphone I have not noticed any affect in sound beyond providing a good seal for noise isolation. I don't know how long these will last, I have used Comply true grip tips on my Sony wf1000xm3 since I got them over 6 months ago and still have an unused pair out of a pack of 3 pairs. I use those buds almost daily for several hours. I discard the tips when they lose pliability, I keep them and my ears clean. Comply tips seem like decent value to me, I'll be impressed if I get more than a month out of a pair with how much I'm using the Etymotics at the moment.
