The model has Immersive Room Feel technology, which is the second version of PSB's Room Full. This technology provides a scientifically developed transfer function that translates the warm, open sound of a live performance into the private world of headphones.
The acoustic part of the headphones is based on dynamic radiators with 40 mm graphene-coated diaphragms, and the Bluetooth version 5.2 adapter provides support for SBC, AAC, and aptX Adaptive codecs. The built-in battery provides 18 hours of autonomy with the noise reduction system turned on and 25 hours without it. The headphones weigh 362 grams.
