Streaming has revolutionised how we listen to music. No longer do you need a wired pair of headphones - you can now beam your tunes through the air to a wireless pair, or to a wireless speaker. aptX has helped this happen.
Not only does it make music sound better, it also makes it arrive without delay, which makes for a much better film viewing experience.

What is aptX?
aptX is a way of making audio files smaller. When a file has been compressed using one of the aptX algorithms, it takes up less space, which makes it easier to stream to a wireless speaker or a pair of wireless headphones.
What’s so good about aptX?
aptX isn’t the first way of shrinking down music files – MP3 has been used to compress audio files for almost 25 years - but some compression algorithms degrade the sound, meaning tunes don’t sound as good when they reach your speaker or headphones. aptX, however, keeps tracks in CD-like quality when they’re beamed wirelessly over Bluetooth, which means tunes sound just as the musician intended.
How does aptX work?
aptX reduces the bit rate of the music file without affecting the audio quality, or introducing latency issues (delays which make the music break up and sound ‘chopped up’).
What advantages does aptX have over other compression methods?
The sound is ‘truer’. Not only does this improve music listening, it also means there are no delays between the audio and video when watching a film or TV show. Lip syncing issues, begone!
Who created aptX?
Qualcomm, a San Diego-based company that makes the chips that go in mobile phones.
Which devices use aptX?
All sorts of consumer electronics devices use aptX. These include – but aren’t limited to – wireless headphones like the Sennheiser Momentum In-Ear Wireless, MP3 players like the Astell & Kern Kann, soundbars like the Philips Fidelio B8, wireless speakers like the B&W Zeppelin Wireless, and music streamers like the NAD M50.2.
