RAI Penta from Romanian audio manufacturer Meze Audio is a high-end in-ear headphone capable of providing unrivalled detail, organic tonality and seamless-fit comfort.

Each RAI Penta earphone features five individual drivers, all of which operate together in sympathetic tandem thanks to Meze’s ‘Penta Hybrid’ technology - where harmonised sound delivery is made possible without overlaying phase issues.

Meze have also implemented an intelligent airflow control system to regulate chamber pressure both in front and behind the driver assembly.

The RAI Penta’s included cable features rhodium plated termination and MMCX plugs. The cable is comprised of four wires each made up of 20 litz strands - totalling 80 strands all together. As with the rest of RAI Penta’s design, these thoughtfully selected details and specs all assist to optimum connectivity, durability and overall high performance sound delivery.


RAI Penta: Shaking Off The WiresFostex TM2 Wireless MMCX adaptor

Thanks to the RAI Penta’s built-in universal micro-miniature coaxial (MMCX) connection, the headphone drivers can be easily affixed to third party wireless transmitters. One such article is the TM2 ear hooks from Fostex which offer Bluetooth 5.0 connectivity for up to 12 hours on a single charge and at an impressive 10ft distance.
