I thought I'd do a quick (ha, right?) post about the tips I have here from gnarlsagan and my impressions on each of them.
I tried them all when I first received them and then used each one (minus any that simply didn't fit me) for a while. Tonight I'm doing more side by side comparisons now that I'm more familiar with which work well with my ears. I think I probably have average to small ear canals. I typically use medium tips on earphones and when available slightly smaller. Small tips that border on ultra small usually just move freely in my ear and large tips usually simply don't go in. Typical small tips fit good. :-P Just trying to give an overview in case you can gauge your tip size as a comparison.
I made a little tip chart for reference of what each looks like. Gnarlsagan identified them all for me to be sure. :-P
I didn't include the stock tips, because I forgot, but I'll just say it was because you already have them anyway. ;-) I'll go in order, left to right, top to bottom.
The dba tips are from the dba02. The small tips don't go in my ears past shallow very well, but they aren't that difficult to get a seal with either as long as I keep them pretty shallow. When I do, the sound is pretty much the same as stock, maybe, just maybe a slight bit peakier in the treble, but if it is, it's so close that it's hard for me to tell. The large tips are a bit too big and round for my ears. They don't really go in enough to be comfortable and fit easily. Instead they resist the insertion and end up causing imbalance and sucked out mids and other odd sound properties.
Philips SHE 3590 Tips:
The golden tips of Midas. These are by far my favorite tips. They seal well, they're thin and flexible and they just work well with my ears. With these the sound is identical to stock with just a touch less overall bass, bringing these into almost the perfect relative flatness of the er4s with better sub bass linearity and more extended treble. They just sound phenomenal to my ears. This is true for both the small and medium tips for me. The large tips are thinner and more bulbous. They simply don't fit my ears in any way. If I even get a reasonable seal or depth they sound hollow and scooped out mid bass and mids. They don't go in my ears well, so I wouldn't use me as an impression for these tips unless you have similarly sized ear canals.
Meelec Biflange Tips:
These require spacers for a tight nozzle fit/seal. They don't seem to seal or fit perfectly for me. The sound is essentially the same as stock if I fit them shallow so they are sealed where the larger flange is a bit protruding from my canal. Almost as though the large flange is fit shallow like it was a single flange. The issue is that this isn't the most comfortable for me. The small flange is then not very tight and sort of tickles or irritates my ear making me want to fix the fit more. If I push them in deeper the sound just gets hollow and doesn't seal properly.
Auvio Single Flange Tips:
These require a spacer for a tight nozzle fit/seal. Otherwise, they actually act as an excellent, already vent-modded tip, because the sit on the nozzle securely enough, but they wiggle and let air through completely. However, even in this configuration, the bass is still o.k., however, the mids sound scooped away like there's a hole in the sound a bit. But the bass is a decent level, lower than stock for sure, but still pretty good. If you push these in deep with this loose sealed nozzle the scooped out mids are mostly repaired. I think the pressure from my ears is pushing the tips and squeezing them against the nozzle to make a bit better seal, but the sound it not completely normal still. Bass is still a bit less than stock and the scooped area is still there a tad, but overall they are pretty similar to stock overall being only slightly worse in my opinion. This is true for the super small, small and medium tips. The medium tips become harder to insert deeply with ease. The large tips are very bulbous and I can only wear them in a specific depth. They don't go any deeper that a fairly shallow fit. They are also the only tips of this type that are a touch raspy if I don't get them sealed right, which is harder as they are more material than really fits well in my ear. If I play with them I can get the same sound sooner or later though, but they aren't ideal.
With the mh1 spacers on the nozzle and the auvio tips over those, the sound is essentially stock at the equivalent depths and seal. I find these a bit easier to get a good seal with, as they just slide in smoother and fit easier, but as far as I can tell the sound is the same as stock. If the seal is better you might hear more bass, but if you get a good seal with stock tips they should be pretty similar. I can't really tell any noticeable difference myself. This is true for super small, small, and medium (orange, red, blue). The larger tips are exactly as described before, being harder to get deep and whatnot.
VSonic Biflange Tips:
These also require spacers like the Audio tips to achieve ideal nozzle seal. It's hard to explain, but with these I get some fluctuation in the mid range. The bass is strong and similar to stock, but there is a bit more mid bass or mids that make thinks a bit darker overall. The treble seems ever so slightly less crisp and airy or bright. The sound good, but the slight changes are moving away from the reference sound in my opinion. Keep in mind the changes are fairly small still though.
Senn Generic Tips:
These require spacers as well. They are a bit harder for me to fit perfectly though. Their round shape and somewhat large size results in weird pressurization or leakage that causes channel imbalance. When I manage to get them sealed tightly they sound pretty much identical to the stock tips to my ears. But the fit is not something I don't want to have to mess with this much, so these aren't for me.
Senn Biflanges Tips (L):
These are my second favorite tips. They are pretty wide but short and stubby. They are a very soft velvety material. The reason I like these is twofold. First, the shape and size only allows a shallow fit, but they fit well. Second, they are very comfortable. I almost forget I'm wearing them after a while, which is odd, because they're the largest tips of the bunch, but I guess the softness and shape help with comfort. The sound is sort of halfway between stock and the philips tips that are my favorite. These have a similar amount of bass, but if they aren't "just right" with fit the treble is ever so slightly less linear. It's probably impossible for me to describe the difference I'm hearing. It could be a few micro peaks/dips, but essentially, it just sounds a bit different. Very very slight, and based on the fit. The bass level is very nice though. Lower than stock. Possible because the design allows a bit more air to escape vs. the tight sealed stock tips.
PFE112/232 Tips (Not pictured):
These fit tightly without spacers. They sound essentially the same as stock, but perhaps a touch less treble extension. Possibly due to the smaller opening on the tip. The small size is possible to wear shallow and deep. The larger sizes are similar to the stock tips in the fact that the shape doesn't really allow easy deep insertion. Overall pretty good tips though.
So for me the winner is the philips small/medium tips with a close second being the Senn Large Biflange tips and the smaller stock tips. These all give me good comfort, ease of use and the most reference sounds.
