AAC Plus vs APTX
320kbps is the pipeline to fit BT sound, so it is best to not recompress if possible. AAC+ is the most widely used algorithm in streaming apps, so therefore by not converting from LOSSLESS to AAC+ to APTX is superior. Apple does not support APTX because of this, I spoke to their engineering team when making this decision.
Our Bluetooth DOES supports AAC+ and many headphones do not, also if the source file is AAC or MP3 up to 320kbps, our headphones will not recompress the file. Headphones that dont support AAC plus will have to convert to MP3, etc...
If you happen to own the only notebook,
or computer
that supports APTX and use music that isnt MP3 AAC PLUS, etc. than you may be able to use APTX. However, APTX is still fitting in a 320kpbs pipe, so I am sure the AAC PLus and APTX algorithm engineers could argue forever on which is best... they are both compressed...
Here is a list of the 2 APTX PCS AND NOTEBOOKS

They are rolling out slowly to UK and EU, etc... For now buy from V-MODA.com and they will be at Selfridges and others within weeks except for gunmetal black.
Last of all, our headphones are flash upgradable, so in the future we could extra features, apps or algorithms if I decide to... but I think that is best done in the core OS or app and NOT by the headphone manufacturer. For instance, my Galaxy S6 Edge has a new system that changes the sound based on a hearing test!!!
