+1. Or if you want to talk about other polarizing options, the Sony SA5000 or an Ultrasone (especially with Ti drivers).

Recent top 3 FWIW:
- Grado RS-1i
- Sony MDR-F1
- Bose QC15-LE

Unfortunately I have not heard the TF 10's or UE 700's. The Westones are the only IEMs I have heard in that price bracket as I got them for a price I couldn't pass up even without an audition.
You may have some luck asking your question here:
Cheers!

Surprised by your high rating of the UE 700, especially since it's actually quite cheap(for head-fi). Might go pick one up if I see it in the new year sales, or maybe the UE 900...hmm.
My top 5 would probably go like this:
1. Denon AH-D2000 with MarkL mod
2. Audio Technica ATH-A900X
3. Personally modded T50RPs(needs a bit more detail)
4. Shure SRH840
5. KRK KNS 8400
None of my IEMs really give me the same level of satisfaction as my headphones, but I don't have any flagship or near flagship IEMs yet.
the 700's rate quite high in head-fi reviews and on other audiophile sites. they are going for cheap now, since Logitech seems to be phasing out most of it's UE line, minus the 900. I think they might be gearing up to go towards more consumer grade/cheaper headphones like skullcandy, sony, philips, ect? The 700's provide crystal clear detail, substantial bass for a BA, and a warm fun sound signature. Are they perfect? no. Are they right up there with some of the other dual BA driver IEM's? yes they are.
1. Sennheiser HD558
2. B&W C5
3. Grado SR60i
4. Sol Republic Tracks Ultra
5. Sennheiser HD280Pro
6. Koss KSC75
7. Bose OE TriPorts
8. Apple EarPods

My top 5 in order:
Fostex T50RP modded (Needs a little more midrange)
ACS T15
Sennheiser PXC450 (Needs a more fleshed out sound, but for an NC headphone, they're pretty darn good)
Monster Turbine Gold
AKG K181DJ
Bottom 5:
MEElectronics M9 (But for $10, they're not that bad)
Beyerdynamic T50P (For $200, they're hilariously bad)
DUNU Crater
Realistic Pro 50 (Too much treble for me now)
Philips The Stretch


I haven't. I almost bought them a while ago though. Are they worse?
I thought people were overstating the disjointed sound of the T50P, but...there's a gap between the mids and the treble that a boat could pass through with ease. They have more bass than I thought they would have though. I kinda like the T50's treble though. If the T70 has some sort of coherency, I'd be up to try it, but their freq graph looks scary.


That sounds like the T50, minus the bass. There's more bass than the K181 (small club mode of course). The mids are tragic. I'm thinking about trading them, but I don't want to subject someone else to using them. I'll try modding them over the weekend.

I haven't kept an of my cans, as I've sold or given away all the ones I've owned.
as for my IEM's, I'll have to say with my amp on bass boost, my HiFiMan RE-ZERO's are simply AMAZING, with beautiful warm sound signature and very detailed, and unbeatable in concert with my amp + cowon s9 or my Fuze. When it comes to playing my SONY mp3 player or my Sansa Clip zip, I prefer my UE 700's. Don't need the bass boost to get great bass depth from the 700's with these players.
If i ignored the fit and comfort issues, then my UE TF 10's would kick both these IEM's ass easily.

Yamaha HPH-200
That's it for me right now. I've owned several others over the years. I'm shopping for another pair now.
