The EPOMAKER x LINSOUL booth at the 2024 International CES had a lineup of ThieAudio in-ear monitors. We begin our tour with the Hype 10. The name apparently stands for "hybrid performance." Each of these IEMs comes with two 10 mm composite diaphragm drivers arranged in an isobaric design to make a subwoofer. These offer a broad frequency response range from 10 Hz to 40 kHz with 105 dB/Vrms @ 1 kHz sensitivity. ThieAudio has these priced at $900 a pair. Next up, is the more feature-packed Prestige LTD, with 1DD + 4BA + 4EST Tribrid setup, and an electrostatic driver that provides a broad 10 Hz to 20 Hz frequency response. Each earphone contains 4 Sonion electrostatic drivers, plus 2 Knowles mid-treble balanced armatures, plus 2 Sonion low-mid balanced armatures, and a 10 mm dynamic subwoofer. The maximum frequency response thanks to this setup is as high as 80 kHz. Sensitivity tops out at 98 dB @ 1 kHz. ThieAudio prices these at $1,300.

While ThieAudio focuses on audiophiles, the Kiwi Ears series is for the mass market that just wants better sound. Kiwi Ears Forteza is an entry-level IEM by ThieAudio, with a much simpler 1 High-Mid balanced armature (BA) + 10 mm Mid-range dynamic driver (DD) + 10 mm Bass DD setup; a regular 20 Hz to 20 kHz frequency response, with 103 dBSPL/mW @ 1 kHz sensitivity; at an attractive price of just $59. Winding things up is the Kiwi Ears Orchestra Lite, a more premium product positioned above the Forteza; with an 8 BA multi driver setup consisting of Kiwi Ears customized HI x2 + Kiwi Ears Customized MID x4 + Knowles LOW x2, per earphone. Available for pre-order now, the Orchestra Lite is priced at $249. Lastly, we ran into a number of face-plate customizations by Kiwi Ears.

Linsoul Audio has been striving to bring the acoustic performance of professional in-ear monitors to the public. After two years of putting passion for perfection to the test and engineering, Linsoul has worked in conjunction with Peacock Audio to introduce the Peacock Flight, which is a superior hand-crafted set of true wireless earphones. Each Peacock Flight unit is handcrafted from start to finish, from the shell molding process to the wiring of the drivers. This is a bespoke design, which makes the earphones be a true one-of-a-kind artwork. The engineering and tuning process is meticulously conducted, and strict testing of each driver component ensures the greatest precision and quality control.

Acoustic performance always comes first on priorities for earphones. Equipped with a Qualcomm aptX HD-compatible chipset, the Peacock Flight supports aptX codecs, which ensures crystal clear sound production with extremely low latency. What's more, the Qualcomm QCC3040 Bluetooth chipset brings a stable connection to achieve the most coherent connection and listening experience. On top of that, the Peacock Flight is also equipped with Qualcomm's latest Clear Voice Capture (CVC) 8.0, which is a noise reduction algorithm that effectively filters out background noise to reduce up to 30 dB of unwanted ambient sound during phone calls. By accurately calculating the position of the caller in relation to environmental sounds, CVC 8.0 allows a pure sound transmission for cleaner and more audible calls.
