Etymotic Research ER4XR Extended Response Earphones

Etymotic ER4 XR with Bluetooth

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 true reference standard for high-definition, in-ear earphones. The ER4 MicroPro series earphones were the first earphones commercialized using balanced armature technology and are recognized as the world leader in response accuracy, to which all other earphones are compared. After more than 20 years, these reference-quality earphones are still the choice of serious sound engineers, audiophiles, and musicians. The ER4XR Earphones, paired with the new Etymotion Wireless Bluetooth cable, are unstoppable and sound better than anything else on the market today. With built-in functionality to answer calls, play/pause, and change tracks, it’s the ultimate in audiophile portability.

The Etymotic Research ER4XR Extended Response earphones deliver a clear and detailed response while providing impressive isolation.

Etymotic Bluetooth cable

The Etymotion BT from Etymotic is an evolution in the Etymotic brand, but also in the Evolution of the Bluetooth cable. Utilizing the latest Qualcomm chip the Etymotion BT supports AptX, AptXHD, and AptX LL giving it 24 bit/48khz lossless capabilities. The Etymotion BT is the first of its kind to have a dedicated DAC and headphone Amplifier installed. The AKM AK4331 with Velvet Sound Technology is far superior to the built-in solutions and will give the Etymotion BT the edge over the competition in sound quality and volume. This cable is designed for use with the latest Etymotic ER Series earphones and will also work on most other earphones that have MMCX connectors.

Accurate Earphone Reproduction

For earphones to have 100% accuracy, a recording of live performances must produce exactly the same sound at the eardrum as the original performance. To achieve this, the acoustic properties of the ear must be factored in. The acoustic resonance and horn effects of the ear change a flat audio signal entering the open ear into sound with a (2700 Hz) high-frequency boost, which is the same response heard at the eardrum in a typical ear.

    These are headphones with astonishing tonal accuracy, compared to almost any other IEM, with just a touch of extra warmth. Hard to beat for the price. Chris M.
