Kiwi Ears Orchestra II Review - 10 Driver IEM Tested

Most in-ear monitors in this price bracket stop at four or six drivers, so the Kiwi Ears Orchestra II ($349.00) stood out to me for packing in 10 custom-balanced armature drivers with a four-way crossover — the kind of spec sheet you'd expect from something priced a lot higher.

What's Inside the Orchestra II

The 10-driver, four-way crossover setup is built to split the frequency range into more precise bands than a simpler two or three-driver IEM can manage. Kiwi Ears lists a sensitivity of 110dB SPL/mW, a 20Hz-20kHz frequency range, and 15-ohm impedance, which together suggest these are easy enough to drive from a phone or dongle DAC without needing a dedicated amp.

Cable and Accessories

The Orchestra II ships with a detachable single crystal copper, silver-plated cable measuring 122cm, and Kiwi Ears includes both 3.5mm and 4.4mm plug adapters with 0.78mm/2-pin connectors — a genuinely useful inclusion if you switch between a phone and a balanced desktop source. The box also includes 12 pairs of eartips across S/M/L sizes and a carrying case, so you're not left buying tips separately to get a proper fit.

Shell and Housing

The housing is a transparent acrylic shell, which Kiwi Ears says is engineered to keep bass response tight and cut down on acoustic resonance inside the shell — a common issue with multi-driver IEMs where extra drivers can otherwise muddy the low end.

What I Liked

10-driver, 4-way crossover setup that's unusual to see at this price point
Comes with both 3.5mm and 4.4mm cable terminations included
Generous 12 pairs of eartips plus a carrying case in the box
Low 15-ohm impedance means no dedicated amp is strictly necessary

What Could Be Better

At $349, it's a step up from Kiwi Ears' entry-level models, so it's aimed more at people already invested in the hobby
Transparent acrylic shells show fingerprints and wear more visibly than opaque housings

Final Verdict

For listeners who want more separation and detail than a basic dual-driver IEM can offer, the Orchestra II's 10-driver setup and included accessories make a reasonable case for the step up.
