When I refer to “inductance”, I’m referring to L2, which is the acoustic pipe connecting the main canal to the acoustic side branch. Apparently (I know a bit about electronics but I’m learning about acoustics as I go), pipes impede transmission of high frequency sound pressure oscillations...

Quote:   To expand a bit on this: I don’t know how confusing the symbols are meant to be, but they are referencing an electronic circuit directly analogous to this acoustic cavity. The circuit shown is an inductor (coil L) in parallel with a resistor (zig-zag R) and a capacitor...

Consulting with ljokerl’s incredible Multi-IEM review, it seems that the Etys best the Apples and Klipschs in sound quality. I then consulted some comparison threads to conclude that the Etys will also likely sound better than the Bose, UE, and Sony options.   Thus, the Etymotic mc3 looks...

How do you guys narrow the field down when you have so many options, all at about the same price?   I’ll add a pair of Sony’s I hadn’t previously considered to the list… now I have:   Apple In-Ear Headhpones (dual driver) Bose MIE2i Etymotic Research mc3 Klipsch Reference S4i...

Quote:   Sorry, I wasn’t able to find the listing you’re referring to, but I doubt that someone is selling a new XBA-3iP for less than $100 .

Bump, please. All feedback is useful, and I’m sure there are plenty of people with similar needs to me on this one. 

Hi everyone,   I always like to keep a pair of sub-$100 in-ears for use on the go, straight from my iPhone. I like to keep the price low since they inevitably get trashed over a year or so of daily use, and I need an in-line mic and playback controls. After browsing around, I think I’ve...

Ultrasone PRO-750 Foldable DJ Studio Headphones PRO750 - eBay (item 270482826126 end time Jan-08-10 13:08:01 PST) Pretty good price for some Ultrasone PRO 750s.

Considering the guy is monitoring on PRO 750s, I suppose that's a good place to start. To my ears, it's absolutely delicious. Tip: append &fmt=18 to the end of any non-HD YouTube URL to get a slightly better audio (and video) track. This code directs you to the H.264 version intended for the...

"6. How will UI be like? UI will be similar to an ancient ipod. " I love your honesty. My RE0's are great, by the way!

As a long-time RE0 lover--and someone who has suffered through several unsatisfying pairs of IEMs before discovering Head-Direct--I would love to audition your latest offering. As a student on a shoestring budget I won't be able to justify buying a new pair of headphones, so the only way I...

I got the RE0 and it's exactly what I need. Extremely detailed, even when compared to my PRO 750s. Very nice balance, if a smidge bass shy (but I'm not a fan of boomy bass to begin with). These are definitely IEM's for the audio purist--I feel as though I am plugged directly into the audio file...

After some digging around, it looks like the RE0 blows pretty much everything else in my list out of the water. Right now they look like my best option! Anyone else want to chime in on this?

I was more hoping there might be someone out there who has actually heard all / most of these and could offer some insight into their relative merits as opposed to a list of preexisting threads easily accessible to me via the search function. Thanks, mwv2, for your insight. I'll definitely...

Hey there, I'm looking for a pair of IEM's under $100. Right now I'm considering: Ety ER6i Ety HF5 UE SuperFi 4 Shure SE210 Shure SCL4 Any opinions/suggestions? Thanks!
