Short answer: both are discontinued, so this only matters if you are buying used, though neither ranks well in its class. Used, the Final Audio Heaven IV is the better pick: it ranks #722 of 865 in-ear headphones by sound quality (rated 2.6/5), against #836 (rated 1.5/5) for the Final Audio Heaven 7. Both are rated below 3.0/5 among the 865 in-ear headphones, so if sound quality matters, consider the ThieAudio Monarch MKIII instead, ranked #1 at $999.
Why pick the Final Audio Heaven 7: It uses 1 x balanced armature with an easy 24 ohm load. Watch for: Discontinued, so it is mainly found used.
The Final Audio Heaven IV is the better-sounding choice. Lower mids sit within about 0.5 dB of target, keeping voices and guitars natural. The catch: Discontinued, so it is mainly found used.
Buy the Final Audio Heaven IV only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the ThieAudio Monarch MKIII instead.

Final Audio Heaven IV Discontinued eBay
Pros: Lower mids sit within about 0.5 dB of target, keeping voices and guitars natural. It uses 1 x balanced armature with an easy 16 ohm load.
Cons: Discontinued, so it is mainly found used. Presence sits about 6.7 dB low with a 12.9 dB dip near 11.2 kHz, so vocals and instruments lose some bite. Sub-bass is 5.5 dB short at 30 Hz, so deep bass lacks rumble. A Harman score of 56 places it in the lower part of the in-ear rankings.
