MILWAUKEE — Koss announced its latest wireless headphones, a foldable over-ear model with both Bluetooth and NFC.
The BT540i headphones are designed for easy pairing, the company said, and feature two built-in mics to cancel ambient noise for enhanced clarity. Other details include AptX codec technology, onboard controls, memory-foam ear cushions, a detachable cable and a lithium-ion battery with eight hours of play time.
They employ the company’s new PLX40 dynamic drivers that are engineered for “personal listening,” Koss said. Frequency response is listed at 10Hz to 25kHz, with impedance of 38 ohms and sensitivity of 100dB SPL.
Although they are not the company’s first Bluetooth model, its last version was released in 2006. Michael J. Koss, Jr., marketing director, noted to TWICE: “We were one of the first to make Bluetooth headphones in 2006, with the Koss Cobalt. That was well before Bluetooth was fully integrated in phones and other devices. Recently, Bluetooth has become ubiquitous and much easier to use, so we embarked in the development of a new Bluetooth Headphone, the BT540i. The rule in development was that the BT540i had to sound great. Our designers’ and engineers’ hard work paid off. The BT540i, which features the new Koss PLX40 elements, sounds incredible.”
The BT540i are currently shipping with a $199 suggested retail. A carrying case is included.
September was a busy month for Koss and Bluetooth. The manufacturer announced its first portable speaker: the BTS1 with a built-in kickstand.
