A wireless neck speaker that connects to the 4K TV BRAVIA XR and allows you to watch Dolby Atmos content with more realistic "360 stereophonic sound" and more realistic "360 stereophonic sound." 

Not only that, but by adding an expression in the height direction to the dispersion of the sound field in the front, rear, left, and right, not only stereophonic material but even 2ch content such as TV dramas can generate authentic three-dimensional sound.

In addition, it is equipped with Sony's exclusive "X-Balanced Speaker Unit," which increases the surface area of the diaphragm by a factor of two. Despite its compact size, the speaker unit's volume is optimized in order to increase sound pressure while simultaneously reducing distortion. Moreover, it is equipped with a passive radiator that effectively boosts the low range, allowing you to enjoy everything from movies to live visuals in the low range with a strong presence. It uses the Bluetooth 5.0 standard for communication, with the profiles A2DP, AVRCP, HFP, and HSP, and the codecs SBC, AAC, and LDAC. There is a frequency range of 20 to 20,000Hz, the maximum communication distance is around 30m, the battery capacity is 2,900mAh lithium ion, the continuous running time is approximately 12 hours, and the charge period is approximately 4 hours.

The external measurements are 244 mm in width, 185 mm in depth, and 53 mm in height, with a weight of around 318 g. It will be possible to use the wireless transmitter "WLA-NS7" (top right image) to create "360 stereophonic sound" when used in conjunction with Sony compatible headphones.

The price is roughly 250 USD.
