Who wins on what

Ranked by what users actually praise

Overall Impression

The dual-DD crossover delivers genuinely impressive, clean bass. Multiple listeners describe the sub-bass as deep, textured, and 'subwoofer-like' without becoming muddy, crediting the crossover design that lets a 10mm driver handle 20-200Hz while a second driver covers the rest. Even self-described non-bassheads were surprised by how controlled and separated the low end stayed across genres like rock, metal, and orchestral music.

Blue 2 and Red offer distinct tuning personalities for different tastes. Reviewers found Blue 2 more exciting and comfortable thanks to a smaller nozzle, while Red was called safer, non-fatiguing, and easier for long sessions, aided by the bundled impedance adapter for extra bass. Some felt Red sounds narrower and lacks microdetail compared to pricier sets, while others praised its balance after break-in.

Comfort and nozzle size remain the most common complaints. Several users flagged the roughly 6.2mm nozzle as too large for smaller ear canals, with one describing it as previously painful. Others praised the tip variety and soft cable despite a stiff appearance. Slight treble sibilance on some female vocals was also noted, suggesting minor EQ tweaks help long-term listening comfort.
