24-Balanced-Armature IEM

The AcousticSheep AST 24BA uses twelve balanced-armature drivers per earpiece for a total of twenty-four, targeting musicians and audiophiles who want detailed stereo reproduction. A detachable 0.75 mm 2-pin cable with an optional inline microphone allows easy replacement or upgrade. The zinc-alloy shell and resin cavity keep weight low while providing passive noise isolation.

Wired 3.5 mm connection limits

A 3.5 mm plug ties the IEM to devices that still offer an analogue headphone jack or a compatible adapter. The 125 cm cable length suits desktop or stage use but restricts movement compared with wireless alternatives. Sensitivity of 103 dB/mW and 30 Ω impedance mean most portable sources can drive them adequately, though very low-output devices may not reach peak volume.

10 Hz – 40 kHz frequency range

The quoted bandwidth of 10 Hz to 40 kHz extends beyond typical human hearing and indicates the driver array’s ability to reproduce deep bass and extended treble harmonics. Buyers who need a different tuning profile or a wireless connection should consider other form factors.

Questions about this item

Should I pick the green, black or silvery version of the AST 24BA?

All three colours share the same 12 BA per side driver array, 30 impedance and 103 dB/mW sensitivity, so the choice is purely cosmetic.

What does 103 dB/mW sensitivity mean when I plug these into my phone?

At 103 dB/mW the AST 24BA will reach loud listening levels from a standard 3.5 mm jack without needing a separate amplifier.

How does the 0.75 mm 2-pin connector affect cable choices?

The 0.75 mm 2-pin socket lets you swap the included silver-plated cable for any compatible aftermarket cable while keeping the same pin spacing.
