The HD4BT is a closed-back, on-ear wireless headphone with 40 mm drivers and a stated frequency response of 20 Hz to 20 kHz. Active noise canceling is rated to reduce ambient sound by roughly 18 to 22 dB, and it can be switched on whether or not a Bluetooth connection is active. A low-latency mode is provided for streaming and gaming.
On-ear controls handle Bluetooth pairing, play and pause, volume and track skipping. A built-in microphone supports basic hands-free calls. Battery life is rated at up to 60 hours with ANC off and 35 to 40 hours with ANC on, depending on the figure quoted, measured at 50% volume.
The headphones connect over Bluetooth 5.4 with a stated operating range of 33 ft and have no headphone jack. They charge over USB-C and fold down for carrying in a bag. The unit is available in black, blue and purple.
