The Linsoul x HBB Jupiter delivers a powerful bass-forward signature with an 11dB sub-bass shelf that avoids bleeding into the mids, resulting in a warm yet articulate low end. Its hybrid driver setup combines a 10mm dynamic driver with Sonion BAs for texture and speed, while four modified EST drivers provide extended, non-fatiguing treble with excellent air and detail retrieval. Vocals and instruments retain clarity despite the bass emphasis, making it versatile across genres like rock and electronic.

Technical performance stands out with precise imaging and a spacious soundstage that feels both wide and deep. The 5-way crossover ensures strong coherence across the tribrid array, though the upper mids occasionally present vocals as overly forward. Comfort is solid despite the 11-driver shells, but the sparse accessories and forgettable packaging feel mismatched for the price.

While positioned above competitors like the ThieAudio Monarch MKIII, the Jupiter justifies its cost with superior resolution and a more engaging bass response. However, its limited marketing and awkward pricing may hinder broader adoption. The included premium cable and ergonomic design are highlights, though tip selection could be more comprehensive.

Audionotions 8.5 Reviewer Score
A step down in techs from U12T (possibly a half step down from U6T). But very well tuned and adds in a dynamic driver punch. Timbre is slightly improved compared to U12T due to the increase in midbass and upper mids energy. On the second hand market, 64Audio IEMs are among the best values in portable audio, the U4S is no exception. Previously Owned
