Doubt so, Bluetooth 5 doesn't really do anything with audio streaming. Check this out: https://habr.com/en/post/456182/, in particular:
> Only one change affected the Classic version within the specification of Bluetooth 5: support for the Slot Availability Mask (SAM) technology, designed to improve radio frequency sharing. All other changes affect only Bluetooth LE (the same applies to Higher Output Power too).
> All audio devices use only Bluetooth Classic. Headphones and speakers cannot be connected via Bluetooth Low Energy. There is no standard for transmitting audio using LE. The A2DP standard, used to transmit high-quality audio, works only through Bluetooth Classic, and there is no equivalent in LE.
> To sum up: buying audio devices with Bluetooth 5 only because of the new version of the protocol is meaningless. Bluetooth 4.0/4.1/4.2 in the context of audio transmission will work the same way.
> If the announcement of the new headphone mentions a doubled radius and reduced power consumption thanks to Bluetooth 5, then you should know that they either do not understand themselves or mislead you. No wonder, even the manufacturers of Bluetooth chips confuse the difference in both standards, and some Bluetooth 5 chips support the fifth version only for LE, and use 4.2 for Classic.
But the cost, even for people who would immediately go buy another pair, does suck. When I used <$20 headphones at the gym, it was reasonable to keep a backup on hand, or a second pair at work or in a gym bag. If I leave my AirPods somewhere unexpectedly my options are to go back and get them. Buying or borrowing a pair of wired headphones aren't even an option in most cases anymore.
Not as a counter to your story, but I know someone who was gifted knockoff AirPods and didn't know it. They were really confused why people liked them so much and returned them within a week.
