Short answer: both are discontinued, and they are rated the same for sound quality, though neither ranks well in its class. (#865 and #900 of 909 in-ear headphones). Either one is only an option used, so choose on condition and price. Both are rated below 3.0/5 among the 909 in-ear headphones, so if sound quality matters, consider the ThieAudio Monarch MKIII instead, ranked #1 at $999.
The case for the Westone UM Pro 10: It uses 1 x balanced armature with an easy 25 ohm load. Watch for: Discontinued, so it is mainly found used.
What the Westone UM Pro 30 does well: It uses 3 x balanced armature. The tradeoff: Discontinued, so it is mainly found used.
Buy the Westone UM Pro 10 or the Westone UM Pro 30, whichever you find used in better condition; both are discontinued. For a new speaker, start with the ThieAudio Monarch MKIII instead.
