Наушники — Focal LENSYS PROFESSIONAL

The Lensys Professional is a closed-back studio headphone from Focal, designed and manufactured in France for work in the studio as well as for portable use. It is priced at USD 699 (EUR 699 in Europe), which places it between the Listen Professional at USD 299 and the open-back Clear MG Professional at USD 1,499 in the Focal professional line. The finish combines black and grey, and the build is mostly metal. It is in effect a studio counterpart to the Azurys, sharing its driver type and 306 g weight.

Key specs that matter

The full-range electrodynamic driver measures 40 mm, and its dome has the M cross-section made of aluminium-magnesium alloy. Its impedance is 26 ohm and sensitivity is 100 dB SPL at 1 mW and 1 kHz. Harmonic distortion is quoted at 0.3% at 1 kHz and 100 dB SPL, and the frequency response extends from 5 Hz to 22 kHz within plus or minus 3 dB. Passive isolation from ambient noise is rated at 23 dB(A). Without the extended headband it measures about 197 mm tall and 152 mm wide.

Engineering and use context

According to Focal, the M profile of the dome lowers directivity, so the result depends less on the exact position of the cups on the ears, and the extra rigidity of the shape reduces distortion. The drivers are also angled inside the cups to match the ear. Small bass reflex ports on the earcups limit low-frequency resonance while keeping the design closed. A magnesium yoke holds the cups, which both swivel and tilt, and the headband length is adjustable. The headband uses aerated fabric with black leather accents and follows a constant curvature, and the memory foam earpads are covered in microfiber and acoustic fabric and can be replaced when worn. Focal points to comfort during long sessions as a main design goal.

Pairing

As it is easy to drive, the Lensys Professional runs directly from the headphone socket of an audio interface, a mixing desk, a laptop or a phone. Two detachable single-sided cables with 3.5 mm plugs are supplied - a straight 1.2 m cable for mobile use and a 3 m coiled cable for the studio desk - along with a screw-on adapter to a 6.35 mm plug. A hard zippered clamshell case of 240 x 210 x 70 mm protects it in transport. The isolation of the closed cups suits tracking with microphones in the same room.

Alternatives

The Focal Listen Professional is the earlier and less expensive closed-back studio model in the same line.
