psb Speakers M4U TWM - True Wireless Micro Planar Earphones

Bass is repeatedly praised for its weight, slam, nimbleness, and control, without clouding the rest of the presentation. The newer TWM review found that very low extension was limited, although it still handled dance music convincingly and was more defined than a JBL comparison.

Earlier M4U coverage found voices clean, smooth, natural, and free of sibilance, with instruments easy to distinguish. For the TWM, the upper-midrange lift can make the presentation more forceful than neutral and reduces tolerance for higher volume.

Open treble brings convincing realism to acoustic instruments and helps the earbuds sound airy. However, the TWM review notes a piercing edge to cymbals and boosted lower treble, while other coverage also heard occasional brightness and less air than ideal.

Reviews hear abundant instrumental detail, clear percussion, and distinct placement of individual instruments. One reviewer found note separation somewhat foreshortened compared with high-end headphones, so complex passages are not presented with flagship-level openness.

The M4U design earns unusually strong praise for an expansive, wraparound presentation. The TWM's stage was said to extend beyond the shoulders, and previous coverage similarly described a rare sense of spaciousness for Bluetooth earphones.

Sharp synth-percussion attack and weighty but agile bass give the sound energetic rhythmic drive. Reviewers generally find the tonal balance cohesive and engaging, though the upper-mid/treble emphasis can make louder playback less relaxed.

The over-ear wraparound layout was described as more stable than conventional true-wireless designs. Earlier M4U reviewers still needed to press the earpieces in for adequate bass, and suggested foam tips could improve the seal, so fit consistency may vary by ear.

Comfort is a consistent strength: the wraparound design places the heavier module against the outer ear rather than loading the ear canal. Reviewers call the soft rubber-clad earbuds discreet and comfortable even over long listening sessions, and the TWM is also recommended for gym use.

These are sealed earbuds, but reviewers caution that the supplied silicone tips may not isolate sufficiently for airplane travel. There is no active noise cancellation mentioned in the reviews, so they are better suited to everyday listening than consistently noisy environments.

The soft-rubber exterior is reported to contribute positively to day-to-day comfort, and physical buttons are explicitly preferred over touch controls by one reviewer. Reviewers say little about long-term durability, charging-case quality, supplied tip variety, or connector and finish longevity.

At $199, Audiophilepure considers the TWM well priced, while HomeTheaterHifi recommends the related M4U design over competing models. The combination of natural sound, unusually broad staging, physical controls, and strong comfort makes its asking price appear competitive.
