Etymotic Release New Bluetooth IEMs – Etymotion BT

Etymotic, the engineering-driven research, development and manufacturing company from the U.S.A., has released a full range of new wireless Bluetooth products – the Etymotion Bluetooth cable, and wireless versions of their highly regarded ER2XR, ER3XR and ER4XR IEM models.

Etymotic Etymotion BT Bluetooth Cable

The Etymotion BT from Etymotic is an evolution in the Etymotic brand, and also in the Evolution of the Bluetooth cable. Utilizing the latest Qualcomm chip, the Etymotion BT supports AptX, AptX HD, and AptX LL giving it 24 bit/48khz lossless capabilities.

A first of its kind, the Etymotion BT has a dedicated DAC and headphone Amplifier installed. Using an AKM AK4331 amplifier with Velvet Sound Technology is far superior to the Qualcomm built-in solutions, which gives the Etymotion BT the edge over its competition in sound quality and power.

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.

The ER2XR provides impactful bass response, while maintaining the clarity in the midrange and highs that Etymotic is known for. The ER2XR offers Etymotic’s renowned isolation, featuring a variety of eartips to provide 35dB+ of noise reduction – so you will hear the detail buried in the mix without raising the volume to compensate for ambient noise.

The high-performance dynamic drivers in the ER2XR can satisfy the in-ear monitoring needs of musicians, while appealing to more casual listeners who like a bit more presence of bass.
