Comply Foam Ear Tips Designed for NuForce, ISOtunes PRO, Q-Jays, Etymotic Research, Westone & Shure, Small, 3 Pairs, Black - Memory Foam Earbud Tips, Earbud Replacement Tips, Made in the USA

I'm using them with my SE535 and Mach 80 IEMs. Please consider that the length is higher then usual.

They are more comfortable than those from the Shure set. They are a bit longer thus going into the eat channel a bit dipper, giving a better feel and sound isolation.

The foam eartips that came with my ER2s and ER4s were rough in my ears, not very comfortable, and kind of finnicky to get a good seal. Oddly, when I reordered Etymotic foam eartips, the new ones were softer but had no memory-foam function at all, so they wouldn't stay compressed to insert. I had to try to stuff them into my ears, and when they did finally seat, they also weren't very comfortable, nor very secure. On top of that, they did a poor job of blocking ambient noise, which is one of the main things I wanted Etys for in the first place. I tried everything to get a genuine Etymotic eartip to work. The stock silicone ones wouldn't seal unless I crammed them in very deep, until I felt some discomfort deep in the ear canal. That doesn't seem workable. I tried the bigger silicone version, and that sealed somewhat better, but still had iffy ambient noise blocking at the gym, and it didn't feel very secure. The original foams were a step in the right direction, but they were rough in my ears, and when they started to get dirty and I wanted replacements, those were not really workable. These Comply ear tips immediately worked better than anything Etymotic had to offer. I don't think they change the sound of the IEMs. They just fit more comfortably and more securely, are easier to insert, and reliably block ambient noise. (SIDE NOTE: Less expensive Etymotic ER2SEs not only sound better to me than their flagship ER4SRs, they have much better specs on paper. Check before you buy!) I don't know about their falling apart as some have reported. I heard those reports about the Ety eartips too, but never had that experience. They're basically foam earplugs with tunnels through them. They fit my IEMs fine--a little snug going on, which is what you want so they come out with the monitors when you extract them. I also try to be careful when pulling them out, as I'd be afraid of them getting stuck in my ear if I just yanked. I don't think this style of eartip is meant to last a long time. And cleaning them with any kind of solvent seems like asking for trouble, in terms of their falling to pieces. It seems to me that, like foam earplugs, I will have to replace them quite often--every week or two if I wear them much. That can get pretty expensive, I admit, but at any rate they work well.

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

Excelente sellado y aislamiento si es lo que buscas. Mejora en efectividad y comodidad (si eres sensible al efecto de vacío) a prácticamente la totalidad de cancelaciones activas de sonido. Apta obviamente para IEMs que casen bien con almohadillas de espuma, si no vas a estar decepcionado con el sonido que dan, lo mismo que en contraste son la guinda del pastel si tu pairing así lo requiere. Lo digo para primerizos, esta no es una almohadilla que introduzca sutiles diferencias a nivel sonoro como ocurre con la mayoría de silicona simples (que no híbridas). Según tu caso, para bien o para mal, cambian notoriamente el carácter de tus IEMs. También, aunque sea obvio, es importante tener en cuenta que la inserción es profunda, por aquello de cómo de a gusto te sientas respecto de ello. El material es cómodo, yo personalmente las puedo llevar durante horas olvidándome hasta peligrosamente de que las llevo puestas incluso, pero lo hago notar para las personas que sean reacias a este tipo de ajuste. Ojalá las hicieran también con protección para las boquillas, entonces serían perfectas para todo uso. Aun así les doy las 5 estrellas porque son de calidad y para lo que ofrecen considero que están a un precio justo.

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.
