That role is a useful starting point for choosing it: the question is whether a studio-oriented wired headphone fits your work, rather than whether every enthusiastic listening description applies to you. The Limited Edition documentation separately identifies a black 80 Ohm option under manufacturer order 717.770. Check that edition and impedance on the actual item. This review uses regular 80 Ohm listening tests as clearly labelled context; it does not pretend that every tester examined the black Limited Edition or your particular unit."},{"claim_ids":["cx_c_cable","cx_c_plug","cx_c_fixed","dt_c_comfort","dt_c_amp"],"kind":"factual","paragraph_id":"dt_p2","text":"The manufacturer specifies a straight 3 m cable for the 80 Ohm model and an analog 3.5 mm stereo plug with a 6.35 mm adapter. Pragmatic Audio confirms that the cable is fixed, so it should not be treated as an externally detachable connection. Before arranging a desk or recording position, check both the available output socket and where the cable will run. Reach can be useful when an interface sits away from the performer, while excess cable still needs managing.

The Gear Detective labels the 80 Ohm cable as coiled, whereas the manufacturer's version-specific table says straight. This article follows the primary table and records the discrepancy instead of combining both descriptions into a fictional specification. Likewise, the black Limited Edition order number identifies a particular option; it does not prove that a regular-model laboratory sample used identical pads or came from the same production run. Buyers comparing listings should verify the edition, impedance, cable and included adapter together, and ask for clarification when those details disagree."}],"section_id":"dt_s1","section_type":"overview"},{"heading":"Sound and comfort","paragraphs":[{"claim_ids":["dt_c_sound","dt_c_treble","cx_c_mix"],"kind":"factual","paragraph_id":"dt_p3","text":"Pragmatic Audio's listening assessment is broadly positive about bass, midrange and the sense of space for a closed headphone, but it also warns that the presentation can become tiring for listeners bothered by sibilance. Those observations describe a reviewer's experience, not a universal definition of neutral sound. headphonecheck.com's tester reached a less favourable conclusion for mixing, finding the 80 Ohm balance too bass-heavy for personal control-room work while preferring its recording role. The disagreement is informative: a sound that makes monitoring engaging can still require caution when deciding how much bass or treble belongs in a finished mix."},{"claim_ids":["dt_c_treble","cx_c_mix","dt_c_use"],"kind":"factual","paragraph_id":"dt_p4","text":"For a practical audition, bring familiar recordings and spend enough time to notice whether upper-frequency emphasis becomes distracting. The existing treble caution remains relevant; a brief impression of detail is not the same as comfort through a long session. EQ is an option mentioned by Pragmatic Audio, but this evidence does not establish a universal correction preset for every ear, pad condition or edition. If your main task is recording, weigh the monitoring role separately from final tonal decisions. If your main task is mixing, the dissenting review is a reason to compare against another reference before committing to judgments made only on this headphone."}],"section_id":"dt_s2","section_type":"sound"},{"heading":"Build, comfort, and ownership","paragraphs":[{"claim_ids":["dt_c_comfort","dt_c_build","cx_c_parts","cx_c_fixed"],"kind":"factual","paragraph_id":"dt_p5","text":"The soft, adjustable ear cups and studio construction support the original comfort case, but comfort should remain a personal check rather than a promised outcome. Try the fit in the position you normally work, including any glasses you wear, and distinguish pressure from sound preference. Serviceability is more concrete: the Limited Edition datasheet lists replacement ear pads and headband padding. That is a useful maintenance route when contact surfaces wear. It does not establish that every component is easy for an owner to replace, that every part is stocked in every country, or that the headphone has an unlimited service life."},{"claim_ids":["cx_c_parts","cx_c_fixed","cx_c_variant"],"kind":"factual","paragraph_id":"dt_p6","text":"The fixed cable deserves separate consideration from replaceable padding. A headphone can offer useful spare cushions while still lacking a plug-in cable at the ear cup, so serviceable and detachable should not be used as synonyms. Before buying for long-term use, identify the matching pad type and a realistic source of service in your region. The manufacturer lists several pad options, including black velour, which makes the exact replacement choice worth checking. No regional stock commitment, repair turnaround or ownership-cost total is established here.

This is one controlled comparison, not four independent population studies, and the sample count and Black Edition identity are not established.

Keep the earlier strengths in perspective: reviewers can enjoy its bass and spatial impression while disagreeing about its suitability as a final mixing reference. Audition first if treble fatigue is a concern, and check source output rather than assuming an amplifier rule from impedance alone. Before ordering, confirm the edition, the straight cable, the adapter and local service options.
