Sound leakage

One review specifically credits the fit and seal with low sound leakage.

Leakage control is better than many reviewers expected at moderate volume, but the open design still leaks audibly in quiet spaces or at higher levels.

Leakage performance is generally good at normal use, though some reviews warn it can become noticeable at higher volumes.

Leakage is improved and often limited at normal volume, but several reviews still report audible bleed at higher levels or in quieter spaces.

The mixed pad materials help reduce leakage, but they do not fully seal sound in.

Leakage is lower than many open-ear rivals but still audible to nearby people once volume rises, especially above roughly 60 to 70 percent or in quiet rooms.

Leakage is present at moderate volume in quiet surroundings, which matches the open-ear design.

Leakage was mixed: some reviews found sound bleed negligible, while others noted more leakage from the on-ear design or at higher volumes.

Sound leakage is a real caveat. The limited evidence points to noticeable outward leakage despite the thick ear cushions.

One reviewer explicitly reports noticeable sound leakage.

Sound leakage is an inherent tradeoff of the open-back design. Several reviews say others can hear your audio, though one reviewer found leakage less severe than expected at normal listening levels.

Sound leakage is a clear weakness once volume rises past moderate listening levels.

Sound leakage is a major tradeoff. Reviewers repeatedly say sound leaks out clearly and can be audible like small speakers.

Sound leakage is a major, repeatedly confirmed trait of the open-back design; people nearby can hear what you are playing.
