Headphones and headphone amps for project studios can be very similar to what you might expect to see at a fine audio salon. After all, good sound is good sound. Some headphones for pro and studio applications have detachable cables so cables may be easily replaced if a performer steps on them.
Headphones for critical listening are often in the semi-open ear category which can be particularly well-balanced for mixing decisions. Sealed headphones are often chosen for the performers/musicians when tracking so the microphones do not pick up any 'bleed' from the 'phones themselves.
Tidepool Audio carries headphones and related headphone amps (with our without built-in audio conversion) from AKG, Avantone, Focal, Grace Design, RME, Rupert Neve Designs and SPL.
