Know before you buy
The SE (Studio Edition) offers a flat, neutral sound profile designed for accurate studio monitoring. The XR (Extended Response) model features a modest bass boost, providing a slightly warmer, more punchy low-end response for casual listening.
No, these earphones have a low impedance of 22 Ohms and high sensitivity, meaning they can be driven easily by standard smartphones, tablets, and portable media players without needing an external amplifier.
Etymotic’s design relies on deep-insertion passive isolation, which blocks between 35 and 42 dB of ambient noise. This is often more effective than active noise cancellation at blocking high-frequency sounds like human voices and office chatter.
Yes, the ER3 series features a detachable 4-foot cable. If the cable becomes damaged over time, you can easily purchase a replacement rather than needing to replace the entire earphone set.
No, the ER3 SE/XR models are designed strictly for high-fidelity audio reproduction and do not include an integrated microphone or remote controls.
These earphones use user-replaceable filters that prevent ear wax and debris from entering the drivers. Regularly replacing these filters is essential to maintaining the balanced armature drivers' performance and sound clarity.
