Final Audio Adagio III - ranked #853 of 909 In-Ear Headphones · Editor's rating 1.3/5

#853 Final Audio Adagio III Discontinued eBay

Pros: Bass is lifted about 6.9 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. Lower mids sit within about 0.9 dB of target, keeping voices and guitars natural. It uses 1 x 8mm dynamic with an easy 16 ohm load.

Cons: Discontinued, so it is mainly found used. A 14.7 dB peak near 6.3 kHz can make cymbals and sibilance sound sharp. The 6.9 dB bass lift can sound boomy and mask midrange detail. A Harman score of 40 places it in the lower part of the in-ear rankings.
