Best praise vs top criticism for WiiM Ultra
Best Praise
+28 pts“Really hoping WiiM comes out with some deals for the Ultra. Really want to get it but don’t want to pay full price.”

ViewTop Criticism
+21 pts“I've had the Wiim Pro Plus and the Ultra. I found that the only thing the Ultra added was a screen. The screen has limited functionality. Everything the screen does and more is on their home application. The screen is also too small to be used as an artwork display, it is also slow. It looks cool but not worth the extra money. Also, the Ultra does not work with AirPlay or Siri. I don't use Siri and AirPlay is limited to 48kbs, but at least it's there. I went withe the Ultra Pro Plus, and have not regretted it one bit.”

Best praise vs top criticism for FiiO KA17
Best Praise
+4 pts“Your hearing the intended tuning rather than the changes that come with your high output impedance sources. Run it balanced and use EQ. The KA17 is just straight up miles ahead of onboard audio, no matter what. And using almost all Bluetooth headphones wired bypasses the built in DSP that makes their tuning not total crap.”
r/HeadphoneAdvice
ViewTop Criticism
+1 pts“I’m experiencing popping and clicking sounds in the Tidal app when playing music in Exclusive Mode. I'm using a FiiO KA17 connected via a high-quality USB cable. I’ve also tried using a Type-C connection, but the same issue persists. The popping and clicking only occur with certain tracks, and only when Exclusive Mode is enabled. I’ve tried various fixes, including installing Soundkeeper, but nothing has helped. However, as soon as I disable Exclusive Mode, the issue disappears—even on the same problematic tracks. Has anyone else encountered this issue? And if so, how did you resolve it? For reference, my FiiO KA17 is updated to the latest firmware. My main settings are: Gain: Low Filter: Fast”
