  1. Unflexible and uncomfortable.

    Posted by Chris DeIuliis on 5th Dec 2015

    I tried a larger pair out, and they were unflexible and uncomfortable. Company let me return them, and they recommended a different pair. Second pair didn't work any better for me.

  2. Great when new.

    Posted by Murray on 3rd Oct 2015

    I use these exclusively with my etymotics. Great isolation and comfort, but the shiny surface of the earpiece wears off quickly. That surface makes the earpiece slightly sticky, which helps them stay put. As it wears off, which happens over just 5-10 uses, the seal and therefore the isolation and bass response suffer. I'm more frequently repositioning to reseal.

  3. Fast delivery and top notch customer service

    Fantastic product! I can hear my band again! I use these every weekend and love the sound isolation that these provide. I received my new tips in 2 days and was given a lot of help from the great staff! I highly recommend Comply foam tips!

  4. Comfortable and Isolates Well

    Posted by Andrew on 28th Jun 2015

    The T-100 tips fit well on my Etymotic ER-6i and remained comfortable throughout a fourteen hour flight. Compared to the stock triple-flange silicone eartips, comfort is drastically improved and isolation is about the same. The Comply tips seem to emphasize the bass response, which is appreciated on these notoriously bass-shy IEMs.

  5. Great comfortable tips

    Posted by Juan Rial on 18th May 2015

    Ever since discovering Comply tips, the first thing I do when getting new in-ears is get a matching set of Comply's.

    I'm using these in combination with a pair of Shure SE315's, and they perform just as I've come to expect from them. They do a reasonably good job of keeping external noise out, which allows you to isolate yourself from your environment at lower listening volumes. They're not magic; a noisy room full of chatting colleagues will still penetrate your private void. But under normal circumstances they strike a pretty good balance between isolation and letting enough sound through so you're aware of what's going on around you. Combined with the softness and comfort foamies provide, these have become my favourite tips.

    The memory foam is smooth and soft. It takes a couple of seconds to expand to fill your ear canal, but once the foam is set, you hardly notice they're there. Depending on the design of your in-ears, you may need to get Tx-100's instead of T-100's, as the Tx series comes with wax guards (keeps your earwax out of your IEM's stems). Check your tips to see whether they already include a wax guard (mesh), or if you need the extra protection of the Tx series.

    First time buyers: get a 3-pack S/M/L and see which ones work best for you. The ideal size is the one that expands to fill your ear canal entirely, giving a good seal, but not so large they exert too much pressure on your ear canal and become uncomfortable to wear after a while.

  6. No seal

    Posted by Anton on 5th May 2015

    I purchased 2x5-pair packs of large T-100 for Etymotic ER-4s because their stock foam tips performed pretty well, so I picked the same external diameter by Comply, because I assumed they should at least be as good. I really did enjoy the sound quality with these tips for a couple of hours, but then the tips just stopped providing the isolation. As a result, the presentation of the lower register dropped way below average. I had to switch back to double-flange silicone tips to regain the full frequency range. At the end of the day, I received zero value for my money.

  7. Best earbud tips. Period.

    Posted by Kevin on 12th Apr 2015

    I couldn't be happier with these. I bought them for my Etymotic Hf3's because none of the stock tips wer the right size for my ears. They are incredibly comfortable and durable. The sound quality is superb, with accurate bass response and no loss on the high end. I found some of the stiffer buds to limit bass to a noticeable degree. These are made with a material that softens at body temperature, allowing for comfort and performance. The best thing is, I've been using these for a couple months and haven't even burned through one of the 3 pairs yet!

  8. Only brand to use

    Posted by Gary Bichsel on 31st Mar 2015

    I have been using the T100 on both my ETYMOTIC ER-4P and the Westone 3 since I bought each. All of the other tips have been useless. Whenever I get a new In The Ear unit it will be with Comply tips

  9. Comfortable, more isolation than expected.

    Posted by Jon on 9th Feb 2015

    I didn't expect this much isolation in earbuds, especially just by changing the tips, Very comfortable, exceeded my expectations.

  10. Tight fit, and durable

    Posted by Tom Brown on 30th Jan 2015

    This is an excellent product, delivers exactly what it says.
