Thieaudio Origin Reviews
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. Jays Audio Youtube Channel
Great set, has a lot of positives and is amazing on bass tracks. Jaytiss Youtube Channel

Interesting sound. It becomes it's own thing. Fit is not great.Super* Review original ranking

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.

TOTL mids. Most 3D and holographic staging yet. Imaging, separation, layering, and staging are all S level - only thing that's holding it back is the darker treble which can lead to softer notes vs, Diva, for example.The most immersive set for rock, alternative, ballads, and classical. An 07M that scales better with better staging. Great clarity and seperation. Treble is pushed back but still clear and evident in tracks (at higher volumes). Could use more low-end (but not an issue) and sharper note transients. Takes you on a journey. Needs to be listened to at high volume for the full effect. Jays Audio Youtube Channel
Very engaging and very natural sounding. Decent technicalities. Instruments sound correct. Staging and imaging very good for an IEM. Very enjoyable. Leans dark and maybe a bit lacking in treble extension but also very easy to just enjoy the music which, at the end of the day, is what we even want from IEMs right? Previously Owned
Comment: My favourite of the EJ lineup. Vocal centric with great clarity and thick note weights in the midrange Bass may be too polite
