Unboxing and First Impressions

The ZMF Bokeh Open arrived in its signature packaging, exuding a sense of premium quality. The Nocturne version, with its striking purple heart grill, is visually stunning.

Technical Specifications and Design

The Bokeh Open utilizes a 50mm Liquid Crystal Polymer (LCP) dynamic driver, offering a unique sonic characteristic. Its 80-ohm impedance and 103dB sensitivity ensure excellent drivability across a range of sources. The patented Atrium Damping System (ADS) promises superior control over driver movement and back waves, resulting in a refined soundstage.

The use of 3.5mm input jacks instead of mini XLR connectors enhances versatility, making it compatible with a wider array of devices. The black anodized aluminum chassis, polished metal adjustment rods, and soft cowhide suspension strap contribute to both aesthetics and comfort. The unique solid wood grill on the birchwood cups adds a touch of artisanal craftsmanship.

Sound Quality and Listening Experience

The Bokeh Open delivers a well-balanced sound signature with impressive sub-bass extension, a neutral yet punchy mid-range, and a sparkling treble. The bass is full and textured, not overwhelming but detailed, adding depth and weight to tracks. The mid-range is clear and articulate, offering exceptional detail and instrument separation without being overly forward.

The treble is extended and airy, providing spaciousness without becoming harsh or fatiguing. Overall, the sound is dynamic, engaging and enjoyable for extended listening sessions. Its versatility allows for enjoyable performance across various genres and sources.

Customization and Tuning Options

ZMF provides a comprehensive tuning kit with nine sound signature variations, achieved by swapping earpads and meshes. The included plastic rings significantly simplify earpad changes, even for novice users. The suede pads offer a softer, more relaxed sound, while the lambskin pads provide a more energetic, detailed presentation.

Different meshes provide varied degrees of treble emphasis. Experimentation with these components enables each listener to tailor the sound profile precisely to their preference. This level of customization is a key selling point of the ZMF Bokeh Open.

Comparison with Competing Headphones

Compared to the Meze 109 Pro, the Bokeh Open offers similar bass extension and treble sparkle but with a slightly more neutral and less forward presentation. The Hifiman Arya organic offers superior technical performance but may be too bright for some listeners. The Bokeh Open boasts a warmer, punchier sound and better low-end extension.

The Audeze LCD-2 Classic excels in mid-range detail and resolution, though it may lack the Bokeh Open's low-end depth and versatility. Ultimately, the best choice depends on individual preferences and priorities, with each headphone exhibiting strengths in different areas.

Conclusion

The ZMF Bokeh Open is a remarkable open-back headphone, offering a well-balanced and highly customizable listening experience. Its strengths lie in its detailed midrange, impactful bass, extended treble, and wide soundstage, making it suitable for a variety of genres.
