What you’ll hear

ER3SE is tuned to be as neutral as possible, with a deliberate hint of presence in the 2–5 kHz region to account for typical ear canal resonance. The result is a listening experience that mirrors live performances and studio captures, making it a solid choice for critical listening, tracking, and casual discovery alike. The official frequency range spans 20 Hz to 16 kHz, capturing deep lows through airy highs with clarity.

• Neutral, flat tuning with a subtle 2–5 kHz emphasis for perceived balance
• Designed for accuracy without requiring an amplifier
• Clear reproduction across the full audible spectrum

Isolation and fit

Isolation is a key strength, helping you focus on your content whether you’re in a noisy environment or indoors. The ER3SE delivers up to 42 dB of attenuation with foam tips, while silicone tips offer around 35 dB. This range supports quiet, immersive listening and better auditioning during editing or mixing sessions.

• Foam tips: up to 42 dB isolation for demanding environments
• Silicone tips: up to 35 dB isolation for everyday use
• Compact shell design suits portable listening and on-the-road work

Who it’s for

These earphones suit audio creators, musicians, engineers, and discerning listeners who want faithful playback and portability. If you’re after a compact, robust IEM with a neutral sound signature and dependable isolation, ER3SE offers a compelling combination of detail, comfort, and value.
