The See Audio Kaguya is a flagship hybrid built around 4BA+4EST per side in a three-way division, using Sonion drivers and a 6N OCC silver-plated Litz cable. The package targets a premium audience with a listed MSRP of $1,399.
Tonally, Kaguya leans neutral-bright: bass is tight and contained rather than heavy, mids are clean with a slight upper-mid lift for presence, and treble is extended yet smooth. Detail retrieval and micro-texture are emphasized, making cymbals, strings, and vocal air stand out without harshness.
Technical performance is a clear strength: imaging feels lifelike and layered, and the stage spreads wider than many IEMs while keeping an intimate, “in-room” feel. Listeners who prefer clarity and treble air over heavy slam will likely appreciate the balance; bass-heads may want more punch. Build, fit, and accessories align with the price tier.
