How we ranked these in-ear monitors

Every pick has at least 100 customer ratings on Amazon and a listing with real specifications. The order mixes two things: how each model compares on the specs below (higher share of the best value in this group scores more), and how widely it is bought. The spec score runs from 9.0 to 9.8 and only compares these picks with each other. A spec the listing does not state is left out and the other specs are re-weighted; a listing with fewer than 2 stated specs is scored at half. We do not test gear in person. Full method.

Buying advice: pro in ear monitors

Count drivers before you compare

Driver count shapes what each model can do, but the driver type matters too. The BASN uses dual drivers, the CCA KZ AS16 Pro uses 8 balanced armature drivers per side, and the Sennheiser uses a single dynamic driver. Compare the driver setup of each model, not just the count, before you pick.

Check impedance and the cable

Impedance is given in ohm. The BASN is 18 ohm, the CCA KZ AS16 Pro is 15 ohm, and the Sennheiser is 20 ohm, so compare the figure of each model with the source you use. A detachable cable lets you replace the cable when you want a different one, and both the BASN and the CCA KZ AS16 Pro have detachable cables.

Look at isolation and warranty

Noise isolation is given in dB, and a higher figure means more outside sound is kept out. The BASN gives noise isolation of 38 dB, the CCA KZ AS16 Pro gives noise isolation to 26 dB, and the Sennheiser gives noise attenuation under 26 dB. Warranty terms differ too: the BASN carries a 12-month warranty and the Sennheiser carries a 2-year warranty, so compare those terms before you buy.
