DSP/EQ tools are a major theme: reviewers mention desk/stand/wall modes, bass extension choices, treble trims, room presets, and more advanced Expert controls, with the caveat that dialing it in can take experimentation.
EQ is a strong point: reviewers highlight multiple presets, a detailed 9-band EQ, BassUp, and vocal effects controls that make it easy to tailor both music and karaoke sound.
EQ control is one of the most-praised upgrades: reviewers highlight a 7-band custom EQ plus presets, making it easier to correct the stock tuning and tailor bass, mids, and treble to different music.
EQ options are a clear strength: multiple presets plus a custom six-band EQ are repeatedly mentioned. AI Sound is frequently described as hit-or-miss, with some finding it adds depth and others finding it inconsistent or degrading clarity.
EQ control is typically limited to a 3-band system with a few presets, but reviewers still find it useful for dialing back bass or adding treble clarity. Those wanting deep parametric control may find it restrictive.
EQ customization is a key upgrade and is repeatedly mentioned as genuinely useful, often with 9-band custom EQ plus presets. Some wish for specific features like stronger bass modes, but the ability to tune and save settings is a strong value add.
EQ customization is limited to presets and toggles (Stereo/Standard/3D Movie/Game, Clear Voice, Bass Extension, and sub level). Reviews note there is no full parametric/graphic EQ, but there is enough control to tailor for different content.
EQ control is mostly limited to preset modes such as Outdoor Boost and Podcast mode, and several reviewers found these modes of limited usefulness. A minority source claims full app-based EQ options, but the broader set of reviews does not support that experience.
