Audio-Technica E-Series In-Ear Monitor Headphones
audio-technica.com

Audio-Technica brings the sonic heritage of its M-Series headphones to three professional in-ear designs: ATH-E70, the flagship model, designed for audio professionals and musicians who demand the absolute best, ATH-E50, ideal for on-the-road artists or producers, and the ATH-E40, a versatile performer from the stage to the street.

Accessories provided with each E-Series set include a 1/4-inch (6.3 mm) adapter, silicone eartips (SX/S/M/L), and a carrying case.

Of Note:
E-Series headphones are compatible with Audio-Technica’s M2 and M3 wireless monitor systems to give performers a comprehensive in-ear monitoring solution.

Technology Focus:
The E70 and E50 employ balanced armature drivers – a single driver in each E50 housing, three drivers per E70 housing – for improved transients, increased efficiency, and extremely detailed mid and high frequencies.

The E40 incorporates Audio-Technica’s proprietary dual phase push-pull driver, which is actually comprised of two facing drivers wired out of phase, reducing harmonic distortion and improving response time, while doubling the power and increasing output sensitivity. The result is a spacious, expansive but detailed sound across a wide frequency range.
