DEVIA Kintone Lite 1 Foldable Bluetooth Wireless Headphones (Black)

Description

The DEVIA Kintone Lite 1 Bluetooth headphones (factory reference JH-820) are supra-aural audio accessories specifically calibrated for the mass retail and mobile accessory market. Designed to offer a reliable wireless audio solution at an ultra-competitive price point, this product is aimed at a general public customer base looking for a versatile, lightweight, and easily portable everyday headset. Its universal matte black colour and sleek lines make it an ideal entry-level product for phone shop and repair shop displays.

Technically, the DEVIA Lite 1 is powered by 40 mm diameter dynamic transducers, configured to deliver high-definition sound with a balanced acoustic response in the low and mid frequencies. Wireless connectivity is provided by a low-power Bluetooth chip, ensuring a stable connection with no perceptible latency within a 10-metre radius. The great advantage of this model lies in its dual-mode architecture: in addition to its wireless connectivity, it includes a 3.5 mm jack auxiliary input allowing for continuous wired use, even when the internal battery is completely depleted.

The headphone chassis is injected with high-resistance ABS polymer, a thermoformed material that gives the headband excellent mechanical flexibility against daily twisting. The ear cups are mounted on pivoting and foldable hinges, reducing the bulk by half during storage or transport. The ear cushions are covered in anti-perspiration micro-perforated faux leather housing memory foam, which ensures effective passive sound insulation against ambient noise while limiting pressure on the ear cartilage.

Workshop Advice & Usage

To avoid returns to the counter linked to premature power circuit (BMS) failures, you must inform your end customers that they should charge the headphones exclusively on a computer USB port or via a standard mains block delivering a maximum amperage of 1A (5W). Using "Fast Charge" or "Power Delivery" (9V/12V) smartphone fast-charging blocks risks burning out the internal thermal controller of the headphones. During the first use, it is recommended to perform a full 2-hour charge to correctly calibrate the chemical cell of the 300 mAh battery.
