Custom-molded IEMs Need ear impressions from an audiologist (UE Pro and JH Audio describe this). Some makers accept 3D scans (UE accepts STL files).
Pro 64 Audio
64 Audio A12t What I use: this is the in-ear I own.
Flagship reference custom IEM. LID is meant to keep the sound consistent across sources with different output impedance (bodypacks, personal mixers, phones). Apex venting is meant to cut ear fatigue over long services.
Fit Custom (from ear impressions). Universal counterpart is the U12t.
Drivers 12: 1 tia high, 1 BA high-mid, 6 BA mid, 4 BA low
Crossover Integrated 4-way passive
Sensitivity 108 dB/mW
Impedance 12.6 Ω (+1/−2 Ω) from 10 Hz–20 kHz
Frequency response 10 Hz–20 kHz
Technologies tia (Tubeless In-ear Audio: tia driver + tia single-bore), apex (pressure-relief vent; modules mX, m12, m15, m20), LID (Linear Impedance Design), 3D-Fit shell

Still to confirm (2) The 64 Audio A12t page also has a second, conflicting spec block (1 tia high + 1 dynamic driver, 98 dB/mW, 9 Ω, 2-way). That appears copied from the 64 Audio Duo. We used the A12t-specific block (12 drivers, 108 dB/mW, 12.6 Ω). A dealer (Pro-Earz) lists 105 dB/mW. Confirm with 64 Audio before publishing sensitivity. Impedance tolerance shown as '+1/2 Ω' on 64audio.com and '+1/−2 Ω' on a dealer page. Specs checked 2026-10-29 (WebFetch of manufacturer page).

Features Variable bass attenuator 0 to +10 dB, FreqPhase waveguide, triple bore
Lead time 4–6 weeks after payment and impressions (per page) Still to confirm (1) JH Audio's marketing claim ('in the ears of nearly every famous touring rock band') is not something we can verify. Don't repeat it as fact. Specs checked 2026-10-29 (WebFetch of manufacturer page).
