Comply 400 Core Series | Memory Foam Replacement IEM Ear Tips for Campfire Audio, Sennheiser, & More | Superior Noise Isolation, Ultimate Comfort, Secure Fit | Black (S/M/L) (3 Pairs)

I bought these for my sleep headphones, and they made a huge difference in comfort. They fit way better than the stock tips and stay in place all night without irritation.They also help with sound isolation on planes, making flights much more peaceful. If you want to upgrade your headphones for better comfort and noise reduction, these are totally worth it.

These eartips are great and definitely isolate noise. You have to be careful with them when you put them on in case it tears. Once you have them in your ears, they should stay there since the foam expands and stays put. The noise isolation is very, very good and the sound quality/volume is either the same or slightly decreased (from what I remember). An example would be when I went to the school cafeteria with over 100 other students talking at the same time. Its pretty loud. I put my music player at 60% volume (Which is at a safe level) and I can actively hear almost NOTHING but the music when it is at its peak volume. I couldn't even hear my friend who was like 1 feet away from me. Pretty impressive compared to silicone eartips.Update 10/20/13: They are good, but they gather up earwax and tear very easily if not handled with care. Upon further observations, using these over silicone eartips give less volume overall so the volume has to be raised. I started noticing that I had difficulty making these eartips (Of the right size) stay in my ear after weeks of use. I have switched back to regular silicone eartips since Comply Eartips aren't very durable. They still give the solid noise isolation though compared to silicone eartips.

Got these for my Soundcore A20 sleepbuds and they improved the sound quality substantially! I will probably try a cheaper brand to compare if they are worth the price in the future, but I can say confidently that they are great.

I bought the multipack since I didn't know what size I needed. First, I put on the medium size on my new Thinksound Rain headphones, and realized they were a bit too big. I was about to put on the small, when I started to struggle to remove the mediums. Soon, the foam completely ripped off, leaving an elastic ring that would not come off the earbuds no matter how hard I pulled. I should note that it was 90 degrees outside today; the temerature inside the delivery truck may have made the rubbery inner layer turn viscous. I eventually was able to force them off, but not without bending the metal mesh on the left earbud.UPDATE: contacted Comply, and they agreed to replace my earbuds! Great customer service. Giving 3 stars for now, may change in the future when I can test them out without damaging my earbuds.

As this was my first Comply eartips purchase, I decided to purchase the multipack as I wasn't sure which ones would fit my ear as I have rather small ear holes. :) As a baseline, I would typically use the smallest ear tips for any included earphones accessory. However, I found that the Ms from comply fitted me perfectly. I should have listened to their advice on their website where it says that 95% of users fit into Medium, and gotten the 3 Ms.Anyway, the earphones I used wasn't on their approved and tested list as I'm using the DZAT-DF10; one of those amazing price performance tips from the chi-fi explosion. I can confirm that the complys fit on the DZAT, albeit with a little bit of tugging. I must say that they do indeed produce AMAZING SOUND. The bass sounds so much richer with the comply tips and they really do isolate a LOT of noise. They are incredibly comfortable, and I haven't felt any ear fatigue or pain after switching to this.Another plus side to this is that it fits in my ear in such a way that the sound doesn't get obstructed by the material. My silicon tips on the other hand that came with my earphones, kept getting mashed up against my ear on one side. Resulting in muted sound and it made it seem that my right side was louder than my left. (I didn't realise that it was my eartips and not my earphones)tldr; Great purchase 10/10 would buy again. Premium price, premium comfort, sound, noise isolation.
