LETSHUOER

Immerse yourself in the unparalleled sonic precision of the Cadenza 4. Letshuoer's proprietary 10mm dual-chambered beryllium coated dynamic driver is the heart of the experience. This innovative driver is both incredibly light and extremely rigid, creating a foundation for unmatched sound reproduction. "It’s a very mature, forgiving, yet engaging product" says Ear Fidelity. Cadenza 4 elevate this performance with a combination of Knowles and Sonion balanced armature drivers. This powerhouse combination delivers rich mid-frequency details, ample treble extension, and resolution that reminds of Cadenza 12. [See Product Desc. For More] But the magic doesn't stop at the drivers. The Cadenza 4 features a three-tube acoustic design with a meticulously engineered, four-way electronic crossover. Letshuoer haven't forgotten about comfort either. Through collaboration with Heygear Technology, they've refined Cadenza 4's chassis for a secure, comfortable fit that allows you to lose yourself in the music for hours on end. The matte-finished CNC aluminum alloy housing not only looks stunning but is also incredibly durable, ensuring your Cadenza4 will be your trusted companion for years to come. The final touch? A luxuriously crafted cable featuring 392 strands of high-purity silver-plated monocrystalline copper. This premium cable not only enhances the fidelity of your audio but also boasts three types of interchangeable 3.5mm, balanced 2.5mm and 4.4mm plugs for seamless compatibility with all your devices.

Letshuoer make fantastic IEMs and equally ways to listen back to them now. Their latest balanced 4.4mm dongle DT03 runs with dual ES9219C chips. What's special about ESS Technology's mobile DACs is that it grants DT03 access to its on-chip analog volume control.  This dongle attenuates volume in the analog domain granting much better signal-to-noise performance than the average competitor's lossy digital volume control. Further pushing decoding precision is an outboard clock that is located right next to DT03's DACs, pushing down phase noise and jitter for a stable decode. After decoding, DT03 is therefore able to validly claim high signal-to-noise ratio – aided by the analog volume controls of its ES9219Cs.

Four-way Acoustic Tubes, Two-way Crossover Circuit. Semi Open Faceplate Design, A Fusion Of Metal And Resin. The drivers are connected to the dual-pin receptacle via a flexible printed circuit (FPC) crossover board. Joint Effort With HeyGear, The Leading 3D-Printing Supplier Four cores of 216-strands, 0.05mm in diameter silver plated copper cable.  DZ4 comes with a standard 3.5mm single-ended plug, featuring a standard 0.78mm dual-pin design. High precision in 3D Printed chassis production to meet ergonomic principles. CNC-milled anodized aluminum casing with semi-open design. Its outstanding sound performance brings exceptional adaptability and compatibility, catering to various usage scenarios from music reproduction, gaming, to basic monitoring needs.

What's most impressive about Letshuoer's EJ07 is how much value they give you, before we even get to their credentials as top earphones for vocals.  This tri-brid overachiever presents you with so much – both from a specification standpoint below $1,000, and sonically too.  One dynamic driver, two balanced armatures and four electrostatic tweeters are beyond just parts, but key components to make EJ07 sing as it does. It's EJ07's performance that makes it particularly memorable in Head-Fi's sea of options, in fact. With one of the sweetest mid-ranges in the business, EJ07 is Letshuoer's way of not drawing undue attention to themselves, but rather just letting the music – particularly vocals and mid-range instruments – flow naturally.

What's most impressive about Letshuoer's EJ07M is how much it's able to give you, for so little.  This tri-brid overachiever presents you with so much – both from a specification standpoint below $1,000, and sonically too.  One dynamic driver, two balanced armatures and four electrostatic tweeters are beyond just parts, but key components to make EJ07M sing as it does. It's EJ07M's performance that makes it particularly memorable in Head-Fi's sea of options, in fact. Tuned for accuracy, there's nothing as special as hearing your tunes as they really are, and Letshuoer step out of the way to render everything accurately with EJ07M.

A Letshuoer double-kill sounds like S08 – releasing new entry-level planar-magnetic excellence and using the chance to debut new technologies. The combination of a new dual voice coil diaphragm, a new coil etching method plus a driver surround combine to create a complete IEM bound to keep newcomers happy for a long time. With its driver surround, S08's driver is capable of making pistonic action more akin to a dynamic driver. When you consider Letshuoer's large 13mm diaphragm and the copious amounts of air it can move, the recipe for deep, plentiful, bass is guaranteed. A 13mm dynamic driver would risk modal break-up at higher frequencies, though. Not Letshuoer's planer driver, kept under the control of S08's magnetic array at all times. [See Product Desc. For More] Being etched across its entire surface with a voice coil means that movements across S08's driver surface are perfectly controlled. Letshuoer introduced a new nanoscopic magnetron sputtering process with S08, etching the planar driver of their S08 earphones yields high stability and long lifespan. Far from modally breaking up at high frequencies, this coil-etching enhances treble resolution and yields high stability and long lifespan. Furthermore, S08's diaphragm is covered with these high-tech voice coils on both sides, improving vibration control, reducing resonance and enhancing transient response. All these aspects translate to Letshuoer's legacy of listenability continue with S08, balancing addictive bass with just a right level of transparency that's not overbearing.

The most wanted Chi-Fi in 2022 because it's entry into the planar-driver world. Pick a 4.4mm version, plug it into the Questyle M15 dac-amp dongle for a whole new listening experience. 

LetShuoer have set the gold standard for entry-level quality, so is it any wonder the colour they chose to build their Eighth Anniversary S12 Edition.  This is a celebration of LetShuoer’s timeless quality no matter the price of entrance, and so they constructed their most emblematic model of a rose-gold titanium alloy. This is a durability that will protect its specially-tuned 14.8mm planar-magnetic driver, with a new tuning that brings it to an ever-wider public. Refined to tame any possible peaks remaining from its original S12 Pro predecessor, S12 Eighth Anni irons out remaining treble issues to produce an effortless, warm listen for all. The interchangeable plugs provided – in balanced 2.5mm and 4.4mm – ensure future compatibility with balanced sources and DAC/dongles. This is an IEM you're intended to start with, and keep with you in the long-term. Check out LetShuoer's other gear here that you can grow with here, or view our other IEMs here.

Letshuoer brought planar-magnetic IEMs to the fore with S12. They are pushing the boundaries of the niche they started by incorporating their R-Sonic passive filtering module into the S15. MOONSTAR Reviews lauds their unique driver execution and Audiophile-Heaven likewise their grain-free sound. Despite maintaining its compact 3D-printed enclosure, the addition of a passive filtering module – a reverse adaptation of a conventional passive radiator – significantly enhances the S15's efficiency via venting.  S15's ability to generate more sound pressure level (SPL) using just a single planar driver. Its ability to reproduce more of the desirable frequencies and spatial cues Letshuoer are after, is therefore enhanced. Working in harmony with the S15's driver, Letshuoer's R-Sonic filtering has a brings out more volume from the limited excursion of the planar driver with added venting as it moves out-of-phase, resulting in SPL output without drawing any power away from the main driver. As a result, the S15 is now capable of delivering a cohesive, spacious, and effortless sound that seems to emanate from well beyond the physical boundaries of its housing. S15's signature is characterised by its neutrality and lack of coloration. To further enhance the value of the S15, it comes with a 216-strand silver-plated copper cable featuring interchangeable 3.5mm, 2.5mm, and 4.4mm balanced plugs. This addition significantly elevates the overall package and worth of the S15. Check out the rest of Letshuoer's range here, or the rest of our IEMs here.
