Do it yourselfJan. 2 2010

These are quite good, but they do wear out. (Mine phones take T-500's, but I assume the same holds for T-400.) I tired of paying four bucks a pair for them. So I got some foam ear plugs (like Hearos http://www.amazon.com/Hearos-Ultimate-Softness-20-Pair-Foam/dp/B001EPQ3H4). I cut them down with scissors and punched holes with a leather hole punch. They are just as comfortable and work every bit as well as the purpose-built tips, but they cost about 25 cents a pair.
o Punch a hole that's small enough to get a snug fit on the sound tube. o Don't make them too long, or the foam will shrink in around the distal opening and reduce the treble. o You could salvage the little plastic inserts out of the foam tips that come with the earphones, but I find they are not necessary.

Mixed BlessingSept. 12 2012
- Published on Amazon.com
Comply foams are good in three cases:
1) the stock eartips on your IEMs strike you as uncomfortable; 2) you need better isolation than whatever ear tips you are using; 3) you have driver flex issues in your dynamic driver IEM.
Numbers 1 & 2 are pretty straightforward. What is driver flex? Read on.
Driver flex is the dark secret of most dynamic driver IEMS. When you shove the driver deep in your ear canal (or even not so deep) the air pressure can sometimes make the tiny thin little driver inside the housing move a little bit. You can hear this happening; when you push the driver in, if you hear a cellophane like wrinkling noise, that is driver flex.
What happens after the driver flexes? Sometimes nothing, all is well. (However, the long term health of the driver may be at risk. There is no real evidence one way or the other, but anecdotally, many online users claim their earphones had shorter lifespans due to driver flex.) Other times, you will have volume level drop in one or both ears, sometimes even no volume at all in the affected drivers. Other times, you will have bass drop out in one or both ears. These two problems - volume level disparity and no bass - are vastly common complaints in earphone land. How many of these complaints are actual defects and how many are due to relatively easily fixable driver flex? Who knows? Note though that balanced armature IEMs seem to be immune to this issue as they work differently in terms of mechanics and seem relatively insensitive to pressure flex.
Not all dynamic drivers have the flex issue. It depends to some extent on driver shape, then on eartip shape and material, then on internal ear canal shapes for each user. My dynamic drivers from Monster and Shure were never affected by this issue at all. Other models I own from Thinksound, RHA, Velodyne, and MEElectronics have the problem to a greater or lesser degree. My BA models - from UE, Etymotics, & Brainwavz - have never had this issue at all.
Comply foams fix the flex issue by expanding slowly after you compress and insert them. This gradual expansion does not create the sudden pressure changes that can mess up dynamic IEMs. Plus the Comply foam is soft and isolates well.
What's the downside?
1) Attenuated treble, warmer sound. Many people like this combo. If you like classical or acoustic jazz, it makes a lot of music far less enjoyable. All earphones I tried various Comply models on had this issue - T100, T200, T400s on Monsters, Velodynes, Brainwavz, UE, & Thinksound. More bass emphasis, less highs. I absolutely disagree with Comply's statement that there is no audible effect on music with use of their foams. There may not be much effect, depending on your music. Jay Z may sound fine, but Mahler's Fifth or Sketches of Spain will sound much the worse with Comply foams. 2) Hard to keep clean. Like Shure "olives" the Complies tend to soak up ear wax that silicone tips would never attract. This interacts with problem 3 below, as the foams then need frequent cleaning. Plus if you take them out with ear schumz and can't clean them right away, the wax dries and looks foul. 3) Durability. Complys do not take well to the rigorous life of portable IEMs. If you baby them, clean them properly and store your phones in a case, you'll get about 2 months of use before they start to lose pieces and compress less easily. If you shove em in your pocket or knapsack, maybe a month of use, barring acute traumatic episodes. 4) Cost! Do the math 1 - 2 months per pair, 3 pairs per package, $ X for cost and shipping. It's like having a mini cable bill. The stock silicones that came with your IEMs will last six months minimum and are dirt cheap to replace if and when you need them.
The Comply TX series costs more than the T series and adds an ear wax filter screen. These don't sound worse than the T series (i.e. still adds warmth, attenuates highs) but they do add cost for a sort of gimmick. Many canalphones already have a filter or grill across the sound tube, and my relatively waxy ears never produced any accumulation of wax on the internal filters on the TX400. Unless you have a regular candle factory in your ear, the 15% price increase is not justified.
The Comply series is an imperfect solution to some very common IEM problems. Unfortunately, there are not many other universal fit solutions available for multi-brands. Shure and Etymotic tips are much more durable, cost less, and don't mess up the sound as much. The Sony Hybrids are also a fine tip choice. Unfortunately, all these other brands do not necessarily fit brands other than their manufacturers. A secure fit is vital, otherwise the tip gets wedged in your ear and you are off to a loved one with tweezers in hand, or off to the ER if you have no loved ones available. Unless you are positive your Shure Olive or Hybrid will fit your specific Brand X, Comply is the only game in town if you don't like your original fitting options with a given earphone.
Comply has a new TS series tip out with an oval shape (a la Klipsch Image S4s) which is said to attenuate the highs less. Haven't heard them myself, they don't seem to be available on Amazon, and, of course, they cost more than the base models. Considering the unhappy cost to usefulness ratio of the TX series, I would say caveat emptor...

I purchased the Sennheiser CX-400 in-ear headphones. I did not like the earpieces that came with the headphones and I am using the Comply T-400 foam tips instead. They are more comfortable and make a better seal for noise abatement.

Better than OEM tips - especially if you can find OEM replacement tipsSept. 20 2009

These replacement foam earphone tips are pretty nice. They more or less work as advertised. They are not easy to attach to the headphones, the fit to the hardware is extremely tight. The foam is very smooth and soft. They are fairly short, so they go deep in your ear. The sound isolation is no better or worse than other tips. I heard a little bit of bass improvement, but nothing remarkable. They are a darker dove gray and smoother than the pictures I've seen.
My only complaint with these, they are expensive. According to the instructions, they should be used for around 3 months. A package of three isn't a year of headphone tips, and that's a bit costly.
There's a bit of a downside to these, if you have dirty ears, well the foam will get very dirty. Don't switch ears with these things (left to right); and don't put these in somebody else's ears. All bad hygeine ideas.
I bought these for Sennheiser CX300 headphones. At first it looked like these are the wrong size. The inner plastic tube is a lot longer than the Sennheiser tips. So you have to press them on the headphone pretty hard, they will not fall off in your ear. Make sure seat the tips down close to the speaker body.
The key to making these work, you have to roll them so they are very narrow. Insert them in your ear fairly quickly and deeply. After a few seconds they expand and seal in your ear. They stay put maybe a bit better than the other tips I've tried. Sound isolation will be obvious if they were inserted deeply and quickly enough.
Minor bass improvement. Feel pretty good in my ear. Short. Decent fit and sound isolation. I liked these, but just wish they were less expensive (although attached to over two hundred dollar headphones its minor - some of the other models, maybe not such a good deal). Check compatibility at their website - its critical to get the right model.

These eartips were a really great investment for a number of reasons: 1) They offer a tight seal for maximum noise isolation and bass response. 2) They are extremely comfortable. I can wear them for hours and not even notice they are there, even though they are inserted deep into my ear canal. 3) It is only $5 a pair, and I have heard these last for months before the foam starts to lose its elasticity. 4) They stay in your ears no matter how much you shake your head or move around
They obviously also have a few downsides: 1) They tend to roll off the highs a little bit, nothing too extreme, but if you are an audiophile like I am just beware (I have my ipod set to treble boost to compensate) 2) The foam DOES degrade after some time, and although it takes awhile, it just sucks. 3) They are extremely annoying to get on and off of the headphones - it feels like the foam will tear off (it doesn't)
Overall, this stuff is a necessary luxury - buy it and you won't be disappointed.
