Features

Overview: The Sennheiser HD 490 Pro (700286) Professional Reference Studio Headphones have an open-back design for a wide soundstage and accurate sound reproduction. The headphones come with two pairs of interchangeable ear cups, one designed for mixing, and the other for producing. The included 71" cable has a 3.5mm plug with a screw-on 1/4" adapter.

Design: The headphones feature Sennheiser\’s proprietary Open-Frame Architecture which limits reflections and avoids standing waves that color the audio signal. The 38mm dynamic transducer is accurate, with a wide frequency response from 5Hz to just over 36,000Hz. The drivers feature state-of-the-art neodymium magnets and an innovated low-frequency cylinder system for powerful low frequencies. The back of the ear cup has an open-mesh metal covering that keeps the headphones cool with natural ventilation. The left ear cup is marked in braille on its hinge (3 vertical dots to spell out "L") to indicate the proper orientation. The ear cups can swivel 180° to fold flat for storage.

Ear Cups: There are two sets of purpose-built ear pads for the HD 490 Pro. One pair of ear pads has a velvety material for producing, while the other pair features a denim-like fabric for mixing. The producing ear pads give extra warmth to the low frequencies, and are soft and comfortable enough to wear for long listening sessions. The mixing pads help provide a more accurate sound for critical mixing decisions. Both types of ear pads can be washed and air-dried to keep them looking new and help them last longer. The pads also feature a specially-built channel to accommodate eyeglasses to prevent the headphones from pressing in on the frames.

Cable: The HD 490 Pro comes with a 71" (1.8m) cable with a straight 3.5mm plug. A 3.5mm (1/8") to 6.3mm (1/4") adapter is included for mixers and other professional equipment with 1/4" connections. The headphones feature 4-pin connections at the bottom of both left and right ear cups. The cable can plug into either ear cup, whichever side you prefer to use. The unused connection can be covered by the provided rubber plug to prevent dirt and debris from entering the headphone. The cable is straight, except for a short portion near the ear cup end that is coiled to eliminate contact noise that enters through the cable.

Packaging: The headphones feature eco-friendly packaging with sustainable and plastic-free materials. The box and internal bracing are made with recyclable cardboard and paper that can be reused multiple times to decrease environmental pollution.

Dear Reality Plug-in: The HD 490 Pro headphones come with a plug-in for dearVR MIX-SE from Dear Reality. The software turns your DAW into the ultimate virtual mixer with advanced spatial audio technology, allowing you to be in the sweet spot while you mix your audio tracks. It simulates an ideal mixing studio with its carefully-designed acoustics, and keeps the sound consistent, even when mixing on different systems.
