Cleer Alpha Black Bluetooth 5.1 headphones, 35 hr, 40 mm driver

What the product is and who it is for

The Cleer Alpha Black is a pair of over-ear wireless headphones that connect via Bluetooth 5.1 and also include a 3.5 mm jack for wired listening. They are built for listeners who want adaptive noise cancellation, multipoint connectivity and long battery life in a single package. The integrated Dirac Virtuo spatial audio widens the soundstage for an immersive experience. Buyers who need active noise cancellation on a tight budget or who prefer on-ear fit should look elsewhere.

Thermals noise and power draw in normal use

The headphones run on an internal lithium-polymer battery that delivers up to 35 hours of operating time on a single charge. Recharging is handled through a cable connection. Passive cooling keeps the ear cups comfortable during extended sessions because there are no active thermal components. The adaptive noise cancellation and ambient modes operate without adding audible fan noise or heat.

The specification that decides fit

The 40 mm ironless driver is the core acoustic component that defines the sound signature and resolution capability of these headphones. It supports high-resolution audio playback over Bluetooth 5.1 with Qualcomm aptX Adaptive streaming. If your source device or preferred codec does not match this driver implementation, the headphones will not deliver their intended performance.
