Satisfactory technical performance. Handles basic detail retrieval adequately in most tracks. Maintains reasonable cohesion in simpler arrangements.

Best bassy set under $1K. Bassy/thicker meta tuning. You can actually feel the reverb and vibration from the bone conduction drivers, great control and low-end texture. Mids and treble are also well extended with no major issues, although it can get sharp at times with the snares/electronic stuff ie, past 3:30 on Time by Hikaru Utada.

The Thieaudio Origin delivers a bass-forward signature with a substantial 12dB sub-bass boost that provides visceral rumble and slam, particularly effective for electronic or hip-hop genres. Despite this emphasis, the neutral midrange avoids bloat, preserving vocal clarity and instrument separation, while the electrostatic drivers contribute a smooth, airy treble free from harshness or sibilance . Its technical performance is strong, offering a wide, holographic stage and precise imaging, though micro-detail retrieval falls slightly short of some competitors in its price tier.

Comfort is divisive due to the large shells, which may cause fatigue or fit issues for those with smaller ears, necessitating careful tip selection for optimal seal . The package includes a high-quality modular cable with swappable terminations (3.5mm/4.4mm) and a distinctive round Alcantara case, though the included ear tips may not suit all users .
