  1. The Best

    Posted by Scott on 7th Jun 2016

    I've used these for years and they make a night and day difference in your earbuds and really helps the lower end bass note , they stay in and are very comfortable, highly recommend..V-Moda + Comply Foam Tips = perfection

  2. Makes the base vivid

    Posted by Unknown on 28th May 2016

    I wanted to trough my earbuds away since the base was poor.
    After I have installed Comply Comfort 400 on them, the base "came to life".

  3. Don't last

    Posted by Jack on 29th Apr 2016

    Two weeks in, normal use: Cracked and broken. Waste of money. Went to hard-ware store, bought some earplugs, cut holes in them = sound the same and heaps cheaper. Try this method first and if you don't like it then buy some of these and then some more in two weeks.

  4. Only one issue - reduces treblie / highs

    Posted by Tigran on 18th Jul 2015

    I am using Comply Ts-400 for years. They last quite well and provide unmatched comfort. They also give great bass/lows and clear mids.

    The only issue is they kill treble. I need to cut the nozzle part with a knife to make the opening wider which brings highs back! I wish they had a model that was already like that.

    Overall, recommended!!

  5. Excellent product!

    Better product than T-400, trebles are much more present.

  6. works great at first, but doesn't last

    Posted by John Giacalone on 5th Jun 2015

    I was excited to find a foam earbud that I hoped would stay in my ear. The Comply buds work great at first, they compress very nicely and then expand in your ear just like a typical ear plug would and they did hold up to a lot of activity. However, within about 1-2 weeks of periodic usage (not a lot), the plugs become very soft and don't compress the same. They don't hold up well to skin oils and even start to split and break. When I contacted Comply with the complaint, they just responded with questions about how I used the buds and cleaned them. I actually received no instructions when I first bought the plug on usage or maintenance so I don't know really what to use for cleaning them. If these foam buds would hold up to normal use better, they'd be perfect, but right now I am very disappointed.

  7. Great fit

    these tips block out most ambient sound when i am at the gym. almost isolating!

    The comply tips will make any earbuds sound like new headphones and 100% better. The trick with earbud headphones is to get a good seal between the tip and the ear, so outside ambient noise is minimized. The comply tips do a great job to achieve this.
    For my ears, I prefer the spherical shape, but I have used both shapes with good success.
    I use JVC HA-FX1X and the bass is phenomenal, considering they are earbuds. The midtones for vocals are very lifelike and the highs are extremely detailed. I would buy these buds again as long as I can use Comply tips with them.

  9. You can't beat this price for good sound quality!

    Posted by Danilo Radakovic on 28th Dec 2013

    After I spent decent amount of money looking for replacement for my Monster Miles Davis Tribute $350 buds, I finally found nice fitting tips. Comfort is incredible, if you buy tips that fits your ears, and sound is something. Let me get this straight, I listen to electronic house music that has to have a lot of bass and I want that bass. I finally found nice replacement tips that can easily replace Monster's original silicon tips. And the best part is that those tips fits my freshly purchased Denon AH-C300 Urban Raver buds, and also my Monster iBeats and many other inear buds that I have! Perfect purchase and I got 5 pairs!

  10. Great at first, but wear-out quickly.

    Posted by Phil on 27th Jun 2012

    Let me say first that I love these. They are really comfortable and create a nice seal in my ears.

    That being said, I find they wear-out a bit too quickly. I find myself having to replace them about once a month. The foam begins to crack and then they just won't stay in my ears.

    Will try other models and see how it goes.
