Ultimate Ears' UE Pro Reference Remastered, there's a new point of reference.

High resolution studio reference monitors tuned for producers and studio engineers. Developed in collaboration with Capitol Studio recording engineers these in ear monitors feature True Tone technology - providing expanded highs and lows, defining our commitment to fidelity.

This is UE's second collaboration with the engineers from Capitol Studios, based on the sounds of their state-of-the-art facility. Proprietary True Tone Drivers extend the frequency range and deliver a flat response to 18KHz. Designed with commitment to fidelity, you can hear the harmonic structure and overtones that are usually missing from most headphones.

All UE Reference Remastered models purchased from April 2018 will feature the brand new IPX connection system, which includes multiple points of redundancy to ensure a more robust, reliable connection system for the new Superbax cable. The Superbax cable is developed for use in extreme environments and is:

Water-proof
Sweat-proof
Make-up & hairspray proof
Costume ready
More comfortable for use with spectacles & hats
Lighter
Stronger
Tour-proof

All custom UE monitors can easily be converted to wireless for hassle-free on-the-go listening with an additional purchase of an IPX Bluetooth Cable: https://www.musicmaker.ie/live-audio/in-ear-monitors/accessories?product_id=33060
