Made for sound engineers and audiophiles in constant motion, Etymotic ER4-PT combines the acoustic characteristics and features of ER4-PT earphones and comes with extra mobile adaptors and accessories for travelling professionals. Also included is an industry-exclusive channel-matching compliance graph.
True high-end sound
An assortment of eartips is provided in the package of the ER4-PT earphones. The triple-flange eartips reduce sound an average of 35dB, which is approximately 98% noise reduction. The foam eartips provide slightly more (42dB) sound reduction. Lowering outside sound allows you to hear the full dynamic range of the recording without having to play it at unsafe levels.
Etymotic invented noise-isolating, in-ear earphones. Etymotic's original insert earphone design, developed for auditory research and medical diagnostics, used balanced armature receivers and established these speakers as the gold standard for high-definition, in-ear earphones.
Decades of research and development.
Etymotic ER4 series earphones were the first earphones commercialised using balanced armature driver technology and are recognized as the world leader in response accuracy, to which all other earphones are compared.
Included with every pair of ER4 earphones is an industry-exclusive channel-matching compliance graph, signed by the Etymotic engineer who precision matched and custom tuned the balanced-armature drivers.
Providing the highest noise isolation of any earphones or headphones on the market today, Etymotic ER4-PT include an assortment of noise-isolating eartips options to ensure proper seal and comfort.
The user-replaceable acoustic dampers are not only a part of the driver housing but also protect the balanced armature driver from ear wax. Etymotic also includes a 2-year warranty.
“If you're after a lean, mostly uncoloured sound then these earphones offer up some of the best sound available from a single driver.”
