Listen to music with the EPH-100...And discover greater detail and clarity than ever before.

The EPH-100 Inner Ear Headphones are the result of Yamaha’s desire to enable you to hear not only clear music, but the sounds of the performer’s breathing or the bassist’s plucking of the strings, and even the emotions the artist put into the music. These new-concept headphones use a 6mm (1/4”) diameter super-compact driver to deliver the sound to your ears in pure form. Superb tuning only possible from Yamaha with its long musical instrument and audio experience reproduces every minute detail. With the EPH-100, you’ll fall in love with your favorite music all over again.

Super-compact 6mm (1/4") Driver Reproduces Pure Sound

The EPH-100 features a 6mm (1/4”) diameter super-compact driver that can be inserted straighter and closer to the eardrum than ordinary earphones. This allows you to hear pure, low-distortion sound without unwanted sound reflections. You enjoy natural, accurate reproduction with all sound sources.

Two-Stage Flange for Powerful Sound and Superior Comfort

The earpad has a two-part flange; the first part smoothly guides the driver into the ear, and the second fixes the earpad firmly in your ear. Tightly sealed for minimal sound leakage, it lets you enjoy powerful bass sound. The snug fit ensures optimal comfort.

Aluminium Body Reproduces Clear Sound with Sharp Definition.

The body is made of high quality aluminium, exceptionally light and hard, it provides a good feel while helping to minimise sound loss. Air outlet holes in the driver unit and exterior adjust sound quality and provide optimum sound emission with sharp definition.

Precision-shaped Aluminium Conveys Luxury and Quality of Yamaha

The body is formed of precision-shaped aluminium with a finish that is resistant to scratching and corrosion. The design, texture and detailed workmanship convey the sense of luxury of a high quality product.


Tangle-Resistant Elastomer Cable with Smart Cable Holder

When carrying the headphones in your bag or pocket, they are firmly attached to the base of the plug. The smart cable holder prevents tangling so the cable can be smoothly taken out and used. In addition, the cable is made of elastomer material that resists kinking or curling. The gold-plated, L-shaped plug is designed with priority on sound quality.

Five Earpads for Maximum Comfort

You can choose from among five earpad sizes to suit your ear size and preference, ensuring maximum comfort as you enjoy your music.

Best IEMs in this Pricerange (Posted on 12/19/2013)
The title says it all - I simply don't think you can do much, if any better at this price.

DESIGN - 4/5 - The drivers are housed in polished, machined aluminum with a multilayered cylindrical design. They look like they'd be heavy and substantial but they're actually exceedingly light, thanks to the aluminum. They look like they'd resist damage better than typical plastic-housed earbuds. The double-flanged tips are a bit odd, and the bigger ones sort of look like mushrooms, but you get used to it, and they create an excellent seal resulting in the best isolation of any IEM I've used.

SOUND - 4.5/5 - Phenomenal. My previous IEMs were Sennheiser CX-300B-ii and Klipsch S4, both solid, midrange earbuds. At first, I wasn't terribly impressed by the Yammy's. However, after about a day's worth of listening, the soundstage opened up dramatically and everything became much more clear and defined. These now blow the other two out of the water, as they should. The sound signature itself is pretty neutral, with a bit of a bump in the bass, which is my preference. The bass is tight and punchy, very well controlled, present but not overbearing. Mids are the strong-suit, with exceptional detail and definition. They're neither forward nor recessed, but have a very pleasing warmth (as is typical for Yamaha) while maintaining detail. Highs are slightly rolled off (I emphasize slightly), but maintain excellent detail as well, allowing you to enjoy the treble without suffering from listening fatigue due to silibance. The soundstage isn't going to blow your mind, but it is still quite open (especially for IEMs). I view it as kind of sitting near the stage at a live performance instead of in the middle of the concert hall. These babies can also handle pretty much any genre, but lend themselves especially well to rock, alternative, country, jazz, r&b, and classical. They'll do just fine with rap and dubstep, but probably won't satisfy bassheads. It's amazing this sound is accomplished with only 6mm dynamic drivers, but also keep in mind they require some moderate burn-in.

VALUE - The MSRP is $200, which I think is a bit overpriced. Typical street price, however, is more like $150, $130 on sale. At those prices, they're an excellent value, and you likely won't do better in this range. The current AG price is $109, which is an absolute steal (and the price I paid). If you have ~$100 to spend on IEMs, this is a no-brainer. They come with several alternate-sized ear flanges, an extension cable, and a carrying pouch. The pouch is decent enough but I'd expect a little better for $200 cans. This is, of course, secondary and a very minor quibble.
