About the brand

Apple deserves credit for making its entire Apple Music catalog available in Lossless (ALAC) up to 24-bit/192 kHz and adding Spatial Audio with Dolby Atmos at no extra cost, while creating Personalized Spatial Audio that uses an iPhone's TrueDepth camera to scan your ears and head to build an individualized HRTF profile applied across Apple devices. The brand has also engineered a proprietary lossless, ultra-low-latency wireless link between Apple Vision Pro and specific AirPods models that bypasses standard Bluetooth limits, and created the open-sourced Apple Lossless Audio Codec (ALAC) that makes its lossless format royalty-free.

About the brand

Koss invented the world's first stereo headphones in 1958 (the SP/3, now in the Smithsonian), effectively creating personal listening, and has continued pioneering firsts including the first self-energizing electrostatic headphone (ESP/6, 1968) and the first dynamic headphone to reproduce all 10 audible octaves (HV/1A, 1974). The brand offers unusually broad limited lifetime warranty coverage on many models and created the modular Utility Series (2021) with detachable cords that let the same headphones work with future devices through different cable connections.
