The app is not on the Play store so Android users will need to sideload if they want it. It gives access to gaming/low latency mode, control options, sound presets, 'find my earbuds' and firmware updates.
A little cheaper if you have coins (free to collect), US$22.52/A$33.87.
Edit: Found a cheaper seller, looks like directly from AliExpress? White only.
You can also get it cheaper with the app if you have 448 coins, navigate to the coins page and scroll down for 20% of via coins. Total at checkout is US$18.31/A$27.54.
Got these, they're really quite good for the price.
Honestly makes me wonder why I spend $$$ on audiophile headphones when it's just as enjoyable with these + not hot / sweaty in summer
Perfect for watching movie or music in bed
