Professional Closed Back Monitor Headphones
Sony - MDR-7506/1

Sony MDR-7506/1

CIRCUMAURAL CLOSED-BACK STEREO HEADPHONESony’s MDR-7506 has long since been a staple of the recording, film and live environments. As a result of their low impedance and closed-back design, the MDR-7506 limits background noise whilst delivering ample volume in the studio/field. Alongside this, the closed-back nature aids in eliminating headphone bleed during tasks such as overdubbing in the studio.

The MDR-7506 features an over-ear design and is perfect for getting good volume from portable equipment with less than powerful headphone amplification. The headphone has a foldable design, making it convenient to store or transport, and its coiled cable allows it to stretch and spring back into place whenever you need a bit more reach.

at a glance • Circumaural closed-back stereo headphone ideal for use in professional applications
• 40mm diameter drive units deliver deeper bass, lower distortion, and wider dynamic range
• Coiled cable allows for better mobility and reach, while also preventing snags from tugging the headphones right off your ears
• OFC cable and gold plated Unimatch plug provides both 1/8" mini-jack and 1/4" TRS phono connectivity
• Neodymium magnets for maximum energy and minimum size
• Compact, foldable design

The Scan Pro Audio Difference

Scan’s Tom Francis has spent many years reviewing and analysing headphones, now with the industry standard GRAS 43AG-7 measuring rig. Below is the frequency response chart (that the manufacturers themselves do not provide) & also the EQ points required to make these headphones even more accurate for studio mix work.

“Sony’s MDR-7506 are a balanced mix headphone under £100. it’s no surprise that well known mix engineers like Andrew Scheps (Adele, Red Hot Chilli Peppers, Beyonce) have used them for years, as even straight out of the box, they will be more accurate than almost every home studio with monitor speakers. They are incredibly lightweight, foldable and are fairly easy to drive, so they don’t need an additional headphone amp. Whilst they haven’t got the forensic detail of the high-end planar headphone models, the sound quality is exceptional at this price, with a surprisingly even tonal balance, that other closed back models can only envy. They are best at medium volume and shouldn’t be driven very hard for optimum accuracy as loud volumes introduce harmonic distortion to the mid-range.

Most closed-back studio headphones have an elevated bass response, which can be excellent for reproducing the feel of club speakers for writing with, however for mixing, an even frequency response is always best and the MDR-7506 are perfect for that.

Sony’s MDR-7506 are a close match to the neutral frequency response curve, which uses the mid range and treble curve developed by Dr Sean Olive at Harman in his latest 2018 study. This peak effectively compensates for the effect the anatomy of the ear and head has on your hearing. Popularised by headphone reviewer Crinacle, the neutral curve has a straight-line target below 1KHz and matches well the type of even response you would find in high end recording facilities and is similar to the response of many high end, open back planar driver headphones.

This is in opposition to the lower frequency response of the full 2018 Harman target curve, which dips in the midrange and boosts up the bass, which does make some sense as it was developed with the aim of being most preferable for music listening to the general public, rather than mix work, where balance is key.

The MDR-7506 only has a couple of regions that go outside this curve (shown on the graph in pink), notably a slight dip at 200Hz and a peak between 3-5KHz. The sub bass response also goes evenly down to an impressive 40Hz, which is a feat many more expensive open back headphones can’t achieve. Almost all closed back headphones have a significant dip at some point in the upper midrange, but the design of the MDR-7506 manages to eliminate this, an impressive feat at any price.”

Tonal Perfection

To achieve a near perfect studio tonal balance, Scan Pro Audio have calculated a compensation curve for these headphones. You can program the EQ points below into any parametric EQ plugin, such as Fabfilter’s Pro-Q 3, which we have used to generate the curve here. This works in the same way as plugins like Sonarworks Sound ID Reference or Toneboosters Morphit, but for FREE!

Although it can’t make entry level headphones sound like a high-end model (as it can’t create detail), it can make them both tonally well balanced.

You should insert the EQ plugin on your monitor bus (if your DAW has one), or as the last plugin on your master bus. Don’t forget to disable the plugin when you export your project, as the correction is only for your headphones. It effectively calibrates what you hear to match the balance the rest of the professional world works to, all for under £100!

If you have a plugin with only 8 bands (Such as Ableton Live’s EQ8) then you can either run two instances in series, with the points split between the two, or omit bands with minor gain changes, such as 1dB movements.

These EQ points can also be used for listening in programs like Equalizer APO (windows) or SoundSource (Mac)”
