The speaker offers an output of 154 Watts through seven speakers: two 'super' tweeters, two front tweeters, two mid-range drivers and a single subwoofer. It also supports playback of various high-resolution music files including mp3, wma, aac, wav, flac, aiff, alac, and dsd. Sony has also included its LDAC technology, which purportedly allows for high quality Bluetooth audio streaming from compatible devices, and has three times the data transmission capability as ordinary Bluetooth audio streaming.
The Sony SRS-X99 also supports multi-room connectivity when used with the SongPal app for Android and iOS. This works similarly to the Sony SRS-ZR5 and SRS-ZR7 which were launched last month at CES. The speaker also uses its embedded Wi-Fi to access iTunes via Airplay or Spotify content via a Wi-Fi network. It can also access music files on a DLNA-compatible PC or Home Media Server, and playback songs via DLNA.
The SRS-X99 is part of Sony's popular wireless range of speakers, and is now the most expensive speaker in the range. The device notably does not have an internal battery, and only works when plugged into an electrical outlet.
