THIEAUDIO was launched in 2019 as a creative endeavor of Linsoul Audio. The goal of THIEAUDIO was to serve as a creative platform for gathering the best teams of engineers to inspire revolutionary audio products for audiophiles and professionals alike. For each project, we hand select the most innovative and renown engineers in his or her field to oversee the design, engineering, and manufacturing of the products. Gathering the momentum from the success of the THIEAUDIO Phantom planar magnetic headphones, as well as the Voyager, Legacy, and Signature series In-Ear Monitors (IEM’s), we are committed to the continual expansion on the limits of high-fidelity audio. We welcome you to join us and experience excellence in musical performance.

Signature Series

The Signature Series lineup of THIEAUDIO represents the pinnacle of our R&D skill sets, combining both the latest technology and innovative engineering to bring together top of the line IEM’s. The first two Signature Series models, the Monarch and Clairvoyance, were hailed globally as among the best IEM’s on the market. Following this success, we are proud to release two new twins tribrids: the Excalibur and Oracle.

The Excalibur and Oracle utilize the latest driver technology from the Danish manufacturer, Sonion - the Electrostatic (EST) tweeter. The EST driver features an ultralight membrane in a small tweeter chamber that is powered by an independent transformer to extend the in-ear monitor’s treble range up to 80kHz. In reality, the utilization of these drivers effectively enhances the extreme-treble response and thereby provides a protracted treble decay, a more airy atmosphere, and enhanced sound resolution. The correct implementation of EST drivers can make normal balanced armature driver earphones seem dull and lackluster in comparison.

THIEAUDIO Excalibur: The Legend Continues

The Excalibur is a 2EST+2BA+1DD tribrid design IEM, featuring three different classes of drivers matched based on their unique functional properties. In short, the tuning of the Excalibur can be described as “exciting”. Featuring powerful bass and crisp high’s, the Excalibur puts out an incredible sound that makes any genre sound its fullest and best. We recommend the Excalibur to those looking for a fun and enjoyable hifi listening experience.

The subbass and bass of the Excalibur is powered by a new 10mm polycarbonate dynamic driver to produce a deeper and more impactful low-frequency sound distribution. The driver has been further optimized with stronger magnets to increase its speed and response. We have chosen a customized American Knowles DFK series balanced armature (BA) drivers to reduce the total harmonic distortion (THD) in this fundamental region of the frequency spectrum, and because of its excellent pinna gain placement. Combined with our tuning capabilities, we are blown away by the performance of our new BA driver selection, and believe they will be an instant crowd pleaser. More importantly, these BA drivers match perfectly with the tonal characteristics of the Sonion EST drivers, creating a natural synergy that brings out impeccable detail retrieval, spacious soundstage, and an airy atmosphere.

Despite the sonic advantages of EST drivers, their relatively low sound output volumes mean that the tuning requires special engineering to balance out all of the drivers to make the EST drivers heard. Our prior experiences working with these drivers have honed our abilities to precisely calibrate all of the drivers in the system to best bring out the EST drivers. We believe that the Excalibur is among the very few IEM’s in the market that fully takes advantage of the full potential of EST drivers, and you’ll benefit from the crisp treble extension that is incomparable with any other drivers out there.

Massive upgrade over Fh3!

As a slight basshead the Fh3 have served me very well for almost a year, but I decided it was time for an upgrade. After dozens of hours of research I opted for Thieaudio Excalibur as my hopeful upgrade. Compared to the Fh3, I can't describe how big the difference is! The Excalibur has much more bass impact and volume (both sub and mid) so the slam and rumble of the Excalibur is unreal chest-throbbing levels of bass. The mid's have much more texture and are somehow never harsh or sibilant. Apart from the insane bass, the treble is where these iem's truly shine, with incredible sparkle and a wide soundstage that make every song sound completely different, by making everything sound almost 3d-like with lots of depth and layers. I can literally listen to the Excalibur all day and it never really gets fatiguing as there is no harshness or sibilance despite being so detailed! The one downside with these iem's is that it took me a whole day to find the right tips for these as the nozzle is very wide! But that may just be for me. Overall, I couldn't be more happy!

Don't save money

Got the Monarch. Took quite a lot of equalization to suite my taste, but now I absolutely love it. My friend borrowed me the excalibur. IT'S NO MATCH TO MONARCH. If you can afford the 150 bucks extra, don't buy this.

Greg Holt

Very disappointed Clarity wasn't good no punch it wasn't that clear it was over $500 way to price Lee he come out with good products but this one no with cost very disappointed

Zhang Shiwei

I used my THIEAUDIO Excalibur for a month and found that there was something wrong with my left earphone. I sent it to test and confirmed that DD on my left was disconnected. I used it carefully and didn't fall. Professionals said it was a DD quality problem. So I hope to get a solution, return or repair. Please recover as soon as possible. Thank you.
