From the manufacturer


Etymotic Research, Inc. is an engineering-driven research, development and manufacturing company. The name 'Etymotic' (pronounced 'et-im-oh-tik') means 'true to the ear'. Innovation, education and hearing conservation are central to Etymotic's mission.

ER4SR Studio Reference

The World's Most Accurate Earphones Just Got Better!

Over 30 years ago, Etymotic invented noise-isolating, in-ear earphones. Etymotic's original design, developed for auditory research and hearing testing, used balanced-armature receivers and established these speakers as the gold standard for high-definition, in-ear earphones.

  • Detachable 5 foot cable
  • High performance balanced-armature drivers
  • Sleek driver bodies with anodized finish
  • Braided cables for reduced microphonic effect

Why Etymotic?

Etymotic designs products to measure, improve and protect hearing, and enhance the listening experience of music lovers everywhere. Audio engineers, musicians and audiologists at Etymotic have generated over 100 patents issued and pending.

Why ER4SR Studio Reference?

ER4SR is Etymotic's new reference standard hi-fidelity earphone for those who demand nothing less than the highest fidelity. The next generation of our long-revered flagship earphone, the ER4S, the ER4SR delivers increased accuracy with greater sensitivity.

Like its predecessor, the ER4SR channels are precision matched within an industry-leading 1dB across frequencies from 100Hz to 10kHz.

The new ER4SR incorporates significant cosmetic and functional improvements, from a sleek, anodized and laser-etched aluminum body to the reinforced, user-replaceable detachable cable. The ER4SR is a must have for discerning engineers, audiophiles, and consumers wanting the most accurate in-ear earphone available.

Specifications

  • Frequency response 20Hz-16kHz
  • Channel matched within 1 dB from 100Hz to 10kHz
  • 35-42 dB noise isolation
  • Impedance 45 ohms
  • Sensitivity: 98 dB SPL at 1kHz, 0.1V drive level
  • 122 dB maximum output
  • Assembled and precision matched in the United States

User Detachable Cables

To detach the cables, pull the cable connector away from the earphone body. Pull straight out-Do Not Twist.

To attach the cables, align the key tab on the cable connector with the notch in the body of the earphone. Press together until it snaps in place.

Changing the Filters

Etymotic earphones have special filters that smooth the frequency response and prevent earwax from entering the earphones. The filters are located at the end of the earphone and are visible when the eartip is removed. When a filter becomes clogged it should be replaced. Filters should be changed when output decreases or sound quality declines.

    I don't know what it's like to be a cyborg, but I imagine this is pretty close
    5 Stars
    I don't know what it's like to be a cyborg, but I imagine this is pretty close
    First off, these are way smaller than they look in the picture. Second, they're easier to insert than I thought, but getting a good fit is harder. They're like timberlands, they take time to get comfy. But once they're in, they're IN.Second off, stereo recordings will have zero depth, but binaural stuff like PC gaming with Dolby atmos has AMAZING depth. They're so accurate they even make the recording's depth accurate!As a Tourette's/Aspergers sufferer who has a multitude of side disorders and mental illness, I have nigh-impossible standards, and I'm more sensitive to accuracy than you're going to be. I love these headphones. It's like the disorders stop, for just a moment, I feel what it's like to be normal.
