This is the Top-Tier universal fit IEM chart/thread. The below chart is designed to help give sonic characteristics and take out opinion, except in the final two columns and possibly the notes. The chart is usually updated daily, or whenever new data is provided and time permits. You might need to refresh [multiple times] the page to see the current chart, as often browsers/servers keep cached copies.
Some thoughts on Top-Tier: germanturkey & KLS, Spyro, average_joe, ClieOS.
The below chart has 4 sections:
- Top-tier universal IEMs
- Top-tier after modding
- Yet to be released possible top-tier IEMs
- Members list displaying what they have heard, as IMO perspective is extremely important.
And there are frequency response charts here (post 2).
If you have additional information to provide, please have your posts contain:
- Changes to the individual boxes in the chart.
- Your proclamation that your think an IEM on the chart is top-tier or not
- What IEMs on the chart you own, used to own, and have spend a good amount of time with
- If I missed any IEMs for any of the categories
- Discussion, points, and counter points to anything and everything top-tier universal IEM related!
Note: please make sure to let us know what you have owned and heard for a frame of reference.
There is additional information below the chart as well as a pdf file. And here is my Copper comparison review (with IE8, FX500, CK10, CK90Pro (modded), RE252, TF10, and some e-Q7)

Unanswered question: What has changes have been made to the TF10 internals?(I asked UE that question via email and linked to this post)
Driver Technology:
There are two main types of drivers, balanced armatures (BA) and dynamic drivers. You can read technical information about BAs here and dynamics here. Dynamic drivers typically are larger and applying Newton's Laws of Motion, require more input power to produce the same volume level (sensitivity), move slower, and keep moving longer than BA drivers. This affects the sound of both types of drivers, with BAs moving less air and being quicker to come to a stop, the bass has less impact and natural reverberation like many are used to. (Most music we listen to is produced by dynamic drivers with they dynamic sound). And even if the bass levels are the same between a BA and dynamic, the reverberations of the dynamic can make the bass much more palatable and strong.
On to treble...the BA treble can be extremely detailed and "etched," presenting every last detail in the source no matter how good or bad the recording/mastering is. Dynamics a lot of the time smooth these details over, which makes for an easier to listen to presentation, but the listener misses out on some of the micro-details present. BAs can bring the details of an instrument right in your face just like you are sitting near an instrument focusing on the details. This may be enjoyable for some, but not for others. It many times doesn't make for the relaxing, smooth experience that a dynamic can deliver. Of course there are always exceptions to any rule
There is a new BA type called (by Grado) a Moving Armature, which is a cross between a dynamic and a BA. Many like the results in the e-Q7, but the jury still seems to be out on the other implementation, the GR8.
