Mitchell and Johnson – GL2 Headphone – Electron Odyssey

Mitchell and Johnson have recently been gaining a positive response from the audiophile necommunity for their design ethos and approach to providing reference quality sound for the consumer market. They are not afraid to implement new technology in their products (or tweak existing approaches) and aspire to create well crafted affordable priced headphones without any compromise to the sound quality.

So we at earphonia.com are excited to be reviewing both the MJ2 and GL2 high quality headphone models.

On this post we will review the GL2 model, the MJ2 flagship model review can be found on this link.

The GL2 headphone is one of their high end models and it uses their own hybrid technology. A combination of traditional 40mm dynamic drivers and an electret-electrostatic diaphragm. This unique diaphragm stores the charge from standard usage, meaning a charge is not required from specialised amps like traditional electrostatic headphones. This approach is called ‘Hybrid Electrostatz Technology System’ by Mitchell and Johnson.

We can now have a much more compact setup and use standard amps to drive these directly, providing many options to drive these headphones.

The GL2 headphones feature:

• An over-ear design
• Walnut wood enclosure
• Naturally tuned response

Technical Specifications:

• Frequency Response: 12 to 40,000Hz
• Sound Pressure level: 115dB
• Impedance: 32 ohms
• Acoustic System: Closed back
• Total harmonic Distortion: <=0.5%

Technically the GL2 has many similar specifications to the MJ2 model, but the FR Range does not extent as far and the THD is higher. Also the frequency response shows different tuning and a less smooth gradient in the lower end especially. These feature just a single cable connector to the left side of the headphone,

Packaging/Presentation/Accessories/Cables

The GL2 headphone comes in well presented professional looking packaging

Inside the packaging there is a hard cardboard box protecting the headphones securely when in transit

The accessories supplied are:
