SIMGOT SuperMix 5

Solid and generous IEMs with unch

As a first set of IEMs coming from TWS, the SuperMix 5 was a fantastic place to start. There's a generous, warm sound with some seriously satisfying bass from the bone conduction drivers. Pair it with a KA13 or similar DAC/amp and the sound gets noticeably richer. Rolling tips is essential — the bone conduction effect varies considerably depending on how well a tip seals and transmits vibration to the ear. Some EQ tuning in Poweramp was needed, though given that I lean toward V-shaped or even basshead signatures, it honestly didn't take more than a slight adjustment to clear up a touch of muddiness to personal preference. My only cautionary note is that the full sound, tuned to taste, can become fatiguing. It delivers across such a wide spectrum simultaneously that it can feel a little overwhelming in longer sessions. Make sure your source files are quality, and then revel in an exceptionally full, immersive experience of the music.

Disappointment

I didn't like these IEMs. The bone conduction driver buzzes at 125 Hz. It's like an extra tambourine in an orchestra. I definitely don't like this effect. The beautiful frequency response is ruined by this effect. The housing of the earphones is uncomfortable; it doesn't fit properly in the ear and is held in place only by the ear tips. The earphones stick out a lot from the ears, like horns, the housing is very large. The cord doesn't lie flat against the head. Maybe there are people who would like these IEMs, but I was completely disappointed with them.

One of the better Harman signature IEM

Should you find Harman tuning safe or uninspiring, these in-ear monitors might just revolutionize your perspective. Their sound profile marries precision with profound technicality, yet it’s infused with the distinctive flair of a bone conduction driver. While its effect isn't overtly dramatic, the enhanced texture and heightened impact are undoubtedly valuable additions. The overall detail retrieval is superb, and the micro-planar driver—a personal favorite for high-frequency reproduction—delivers a generous expanse of air with vibrant sparkle and crystalline clarity. Considering its price point, the SuperMix5 stands out as an exceptional all-rounder, excelling across most aspects without ever sounding dull or overly reserved. It's a highly recommended, impeccably tuned quadbrid.
