Bowers & Wilkins unveiled the PI7 and PI5 TWS headphones, which the manufacturer claims provide high quality sound in a wireless solution. The older model PI7 supports the Qualcomm aptX codec, has six microphones and is equipped with adaptive noise reduction. The PI5 version is equipped with four microphones and has a simplified noise cancellation system. New items support the work of voice assistants Siri and Google Assistant. The older model can work up to four hours on a single charge, the younger one provides 4.5 hours of playback. The PI7 model implements the ability to connect a charging case via a 3.5 mm jack or USB port to a sound source, while the case transfers sound to headphones. Both models support wireless charging. The headphones will be available in two colors, the older version will cost $ 399, and the younger one will cost $ 249.
