In a world where I run Apple I'd name the product line as follows, and refer to the device by year (all Apple Watches made of aluminum, available in black/silver/gold/rose gold colors, keeping only the sport band and nylon band so there are only two price points dependent on the screen size you want):
Apple Watch (38 mm)
Apple Watch (42 mm)
iPhone Mini (4")
iPhone (4.7")
iPhone Plus (5.5")
iPad Mini (7.9")
iPad Air (9.7")
iPad Pro (12.9")
MacBook Mini (12")
MacBook Air (14")
MacBook Pro (16")
Mac Mini
Mac Air (iMac rebranded- makes no sense to have one Mac in the whole lineup have an "i")
Mac Pro
Also I'd get rid of about 75% of the Beats lineup, completely removing the options that are corded-only (the Bluetooth headphones come with a 3.5mm cable in the box) and removing the "Wireless" moniker since they'd ALL be wireless, leaving only:
BeatsX (4-5 colors)
PowerBeats3 (maybe 4-5 colors)
BeatsSolo3 (4-5 colors)
BeatsStudio(2?) (4-5 colors)
Premium headphones should equate to either a cordless connection or a choice between corded and cordless- not spending $200 and then wishing you hadn't when the 3.5mm cord breaks and ruins the headphones.
...But I don't run Apple. So I'd settle for my first post's suggestions.
