“Update: I got the headphone and I have been using it for almost 2 months. Best headphones I ever owned in terms of clarity. Perfect for music producers.”— @HifyTech on YouTube
“To anyone here thinking of buyint the 700 Pro X: Do it. I've owned a pair since the very first day they were available in the market, use they daily, and they still look fresh out of the box. The sound is amazing, still on the same pads and the comfort is unmatched.”— @bananawarlock3981 on YouTube
“I'm not kidding, this thing feels like a vice on your head. Add to that the extra weight and the excessive bass, and you have a headphone that quickly fatigues both your head and your ears.”— @Nayah9 on YouTube
“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

Owners point the Beyerdynamic DT 700 PRO X at people producing or monitoring music who need a closed back, and gamers and everyday listeners who want one pair for music and games.
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 Beyerdynamic DT 700 PRO X is build durability is the most common complaint: headband padding coming unglued within months, and plastic sliders and earcup arms cracking, often within two years. 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.
