“I keep coming back to them frequently as I love their weight, fit and sound, especially for mixing music.”— _crackerjack73_ on Reddit
“Recommendation for the AKG 712 Pro, and perhaps tryout the k702 earcups for more detailed sound and wider soundstage.”— Bastelkorb on Reddit
“the 712 fell way short with boosted bass that created a muddled midrange and a tepid soundstage not as pinpoint accurate and open as the other 7 series.”— rajmahid on Reddit
“I think these sound leagues above the original Ace tho thanks to that custom dual-ring magnet motor. The bass is deep and tactile while the sound stage is far more wide and open in comparison to its predecessor.”— @ventus77777-h on YouTube
“I have the Ace Ultra and i love them....especially with my Sonos Theatre system...i had the first ones and i like these ones more....no complaints whatsoever”— @SpankyGolfaddict65 on YouTube
“do NOT buy these for TV audio swap. the feature sucks. source: i own these headphones.”— @Beanz0911 on YouTube
Real owners lean toward the Sonos Ace Ultra: 56% of 18 owners recommend it, vs 50% of 80 for the K712 Pro.
Owners point the K712 Pro at gamers wanting pinpoint footstep imaging and a huge soundstage for FPS titles, and classical and orchestral listeners who want spacious, airy presentation over bass slam.
Owners point the Sonos Ace Ultra at sonos soundbar owners who want to watch TV on headphones, and original Ace owners who want more bass.
The most-cited downside of the K712 Pro is bright, fatiguing treble with a dip in the mids that some owners find harsh or off-putting on longer listening sessions. For the Sonos Ace Ultra, it's the TV audio link to a Sonos soundbar drops out, picks up static, or fails to connect for a few owners, and one returned a pair over it.
