Noble Audio Knight
The short version
The Knight is Noble Audio's most affordable IEM at $289: a tribrid with a 10mm dynamic driver, a Sonion balanced armature and a piezo super tweeter in CNC-machined aluminium shells with an acrylic faceplate. Its identity is the midrange, described as rich, emotive and natural in timbre, with acoustic instruments sounding lush for the price.
Pros
- Rich, emotive midrange with natural timbre, the clear focus of the tuning
- Controlled, balanced bass that never turns bloated
- Precise imaging with placement that is easy to pinpoint
- Premium CNC aluminium shells and one of the better stock cables at $289
- Easy to drive from phones and dongles while still scaling with better sources
Cons
- Cable ships with a 4.4mm balanced plug only and no 3.5mm adapter
- No hard carrying case in the box
- Large shells and long nozzles may not fit smaller ears
- Micro-detail and top-octave resolution are good but not class-leading
- Treble character is disputed: bright and raw to one listener, dark and subdued to others

What the research says
Bass is controlled and balanced rather than boosted, with limited sub-bass in one account and punchy mid-bass in others, but never bloated. Imaging is precise and placement easy to pinpoint, yet stage size splits opinion: large in one review, modest in dimensions in another, and deeper than it is wide in a third. Treble splits as well.
One listener hears it bright with a raw edge and slightly sharp female vocals; others hear it smooth or slightly dark, with one noting no sibilance. Detail is good but not class-leading, with micro-detail slightly muted by the relaxed top end. It is easy to drive and the stock 8-strand cable is among the better ones at the price, but the cable ships with a 4.4mm balanced plug only and no adapter, there is no hard case, and the shells are large with long nozzles that may not suit small ears.
The result is an easy recommendation for vocal and acoustic listeners who value tone over sparkle.
