Know before you buy
The ER2SE (Studio Edition) is tuned for a flat, neutral sound profile that prioritizes accuracy, making it ideal for professional monitoring. The ER2XR (Extended Response) features a slight bass boost, providing a warmer, more engaging sound signature for casual listening.
These earphones use passive isolation, which physically blocks sound rather than using electronics. They are highly effective, capable of reducing external noise by 35-42 dB, which often outperforms active systems for blocking high-frequency sounds like human speech.
No, the ER2 SE/XR models are designed strictly for high-fidelity audio reproduction and do not include an integrated microphone or remote controls.
Yes, both models feature detachable cables. If the cable is damaged, you can easily replace it without needing to purchase a new pair of earphones.
With an impedance of 15 Ohms, these earphones are very easy to drive. They will perform well with standard smartphones, laptops, and tablets without requiring a dedicated external amplifier.
Yes, they are lightweight and feature a slim design. However, because they are designed to fit deep in the ear canal for maximum isolation, it may take some time to get used to the fit if you are not accustomed to deep-insertion monitors.
