COMPLY P-Series Mixed Black earbuds x3

I've tried several other foam tips for my etymotic IEMs (including some extra options etymotic provides, besides the ones they give you with the ER4s) and I also have custom made silicone molds. First of all, the isolation with these tips is better than everything else (including the highly expensive silicone molds). Secondly, comfort wise, these are much more comfortable than the other foam tips, and minimally less comfortable than the silicone molds (you feel a slight pressure) ie, you don't really start to get tired of the IEMs for at least 2-3 hours (truth is, with the custom silicone tips, you could wear them all day long). And finally and more importantly, the sound is better than EVERYTHING else, including the molds!! (which I didn't expect). It seems that a) the molds don't allow the tip to reach so deep into the ear (although it's extremely deep) and the bass somewhat suffers as a result. and b) the sound of your footsteps if you have to walk, or any other internal sounds which are unavoidable when wearing IEMs, is not so pronounced as with the silicone molds! So in the end, it seems that the only thing these extra.... 150£ got me was (much) extra comfort. The next best thing (or THE best thing, if you don't have to use your IEMs for more than a few hours at a time) are these foam tips though, and for a tenth of the price..... Just ordered a second packet.

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.

I've been using using comply tips on all of my IEMs for years now, started with medium T-100s which I actually still have 1 pair left, they are small, minimal size really, 10mm length 12mm diameter, the best ones I've had were T-100 large from early 2013, 14mm length, 13mm diameter, no guard on them, but when I re-ordered those I found that they had changed the design to a shorter wider version, closer in length to the original mediums, these measure roughly 14mm diameter and as such they seem to exert slightly too much pressure on my ears and lack the depth to get good isolation. So I switched to the P-series which are much longer, 15mm + length, 13mm diameter, they also have a tapered core unlike the T-100s, so they feel slightly different when rolled and possibly isolate better. The issue I found with these though is that they are actually TOO long, this might be great for use in very high noise environments, but for general usage I found that the hole would actually close up and muffle the sound because the insertion was too deep, so I had to actually cut the end off to hear the sound clearly, its difficult to get a straight cut since they are foam and you lose the nice rounded shape that complys have. After that you might notice an additional problem, the long core inside resonates strongly at certain frequencies ( around 4 to 8 KHz ) like a reed in a wind instrument, adding a slight harsh sound to the music, to fix this I had to force back the remaining foam past the end of the core and cut around 2-3mm off, not easy. I give it a high rating anyway because from what I've seen theres nothing else you can buy that will produce the good results you can get with this.

Great sound isolation - take note they protrude into the ear more than others

Very low quality plastic breaks all the time. Plastic is not properly threaded. Foam dissolves after a few weeks of use. I did not enjoy picking foam bits out of my ear. They block out sound well, while they are not dissolved though.

After getting my Shure Aonic 4s I have been trying to find a foam ear tip that seals and is as comfortable as the original 3 flange silicone ones. These tips are super comfortable I can wear them for hours with no strain, the box of different sizes lets you find the perfect fit. They seal really well in the ear and the sound quality is not hampered at all. The extra length on these compared to other models definitely helps getting the proper fit. I would suggest these to anyone looking for replacement foam tip.

Blocks outside noises really well. I no longer have to push my music volume to dangerous levels just to drown out the train noise.

Sono morbidissime e si adattano perfettamente al condotto uditivo. Non esercitano pressione quindi rimangono confortevoli anche dopo lunghi usi. Io le ho applicate a delle Etymotic ER4P ed il suono è notevolmente migliorato rispetto a quando usavo i plug inclusi con le cuffie (in particolare usavo i triple-flange). Credo questo sia fondamentalmente dovuto al miglior isolamento offerto dai plug Comply che a sua volta migliora ovviamente la percezione del suono, specialmente per le gamme basse. Sulla durata non so dire. Le uso da due settimane. Al tatto sembrano molto delicate, ma fino ad ora non hanno mostrato segni di usura. Le consiglio.
