Muse HiFi Power vs ISN Audio Neo 3

Last updated: October 17, 2026

Short answer: the Muse HiFi Power on measured sound quality, the ISN Audio Neo 3 on price. The Muse HiFi Power ranks #973 of 1369 in-ear headphones, rated 3.2/5, at $199. The ISN Audio Neo 3 ranks #1054, rated 3.1/5, at $99, $100 cheaper.

Muse HiFi Power vs ISN Audio Neo 3

Why pick the Muse HiFi Power: A 14.5mm planar magnetic driver with about 2.3 dB of extra bass and sub-bass that stays within 6 dB of target down to 20 Hz, for a full, warm low end. The catch: Squig.link measurements show a 12.7 dB peak near 11.9 kHz on top of a 6.5 dB dip near 6.5 kHz, so the lower treble sounds dim while the very top can add a hissy sheen.

The case for the ISN Audio Neo 3: A published AutoEQ preset corrects its response toward the Harman target, so a few minutes of EQ setup closes most of the gap. The catch: Treble about 2 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.

Buy the Muse HiFi Power when sound quality outweighs the price for you, and the ISN Audio Neo 3 when the price outweighs sound quality instead.

Frequency Response Compared

Both headphones’ measurements overlaid on the Harman target. Above the target sounds louder in that range, below it quieter. Each curve is the median of several independent measurements, shifted so its 500 Hz to 2 kHz average sits at 0 dB, so only the tuning is compared.
