Youtube Video Summary

ROSESELSA QuietSea II arrives as a dual-dynamic around $70 with playful packaging, a metallic shell, and a flat 2-pin socket. The shell is small and comfortable with a metal nozzle that grips tips well, but the stock fabric cable is notably microphonic. Accessory spread is generous (multiple tips, pouch, cleaning tools), though isolation is only moderate.

Sonically it’s a bass-forward tuning with thick, rich mids and pleasant upper mids, set against a treble that rolls off in the upper air. The measured curve shows an early bass rise (~200–250 Hz) that “cooks” parts of the lower mids; flattening that region and extending air would yield a more balanced presentation. Still, the set delivers fun, punchy impact and a decent sense of space for the price, reading as a bold, slightly V-shaped take.

Positioning within the lineup, it contrasts models with crisper top-end by offering a relaxed upper treble that suits treble-sensitive listeners and smaller ears, while others may miss sparkle and extension. Technicalities are appropriate for the bracket; the tuning is quirky but engaging and feels like a clear step up from the original. Overall, this earns a solid 3-star verdict: distinctive, enjoyable, and competitive—just not the pick for those chasing maximum air and detail.

The ROSESELSA QuietSea II is a single-dynamic-driver (1DD) IEM built around a 10 mm diaphragm that combines a PEEK + carbon-copper dome and a dual-magnetic, dual-cavity motor. The brand highlights its ORBITA acoustic architecture and includes a modular 3.5 mm/4.4 mm OFC cable; current pricing sits around $63–70, with an MSRP of $69.99. These core specifications and pricing are documented on the product page and retailer listing.

Sonically, QuietSea II targets a neutral-warm balance: bass is modest with a mild sub-bass lift, mids are smooth and present, and treble stays non-fatiguing rather than sparkly. Community impressions describe it as “smooth” and “musical,” which aligns with a relaxed upper-treble and a focus on easy listening over analytical edge. These subjective takes are echoed in early YouTube coverage of the QuietSea II.

Technicalities are competent for the sub-$100 class: imaging is orderly with a stage of average width/depth, macrodynamics are restrained, and microdetail prioritizes smoothness over bite. Efficiency claims tied to the ORBITA design suggest easy drivability; in practice this type of tuning suits long sessions and casual music mixes more than critical, treble-centric listening. Given the price bracket, the overall value is solid, especially if a laid-back tonality is a priority.
