Sony SRS-NS7 is a premium wireless neckband speaker with virtual Dolby Atmos surround sound support. It is powered by two of Sony's X-Balanced drivers and two passive radiators in an up-firing configuration.
The SRS-NS7 comes with enough battery power for up to 12 hours of continuous use; it can also charge up in 10 minutes for an hour of additional use. In essence, it is designed as a more comfortable indoor substitute for headphones, even though it comes with IPX4 rating (which in this case is to secure the speaker during house works).
The SRS-NS7 comes with the WLA-NS7 wireless transmitter, which connects to sources such as TV or computer via optical or USB connection. The WLA-NS7 transmitter minimizes audio delay, even though the SRS-NS7 can work alone via Bluetooth 5.0.
