Unleashing the Power of Sound: A Review of the SIVGA Lyrebird Quad-Driver Hybrid IEMs

I had the pleasure of reviewing the impressive flagship SIVGA Nightingale PRO in December 2025, as well as the over-ear SIVGA Robin and SIVGA Phoenix before that. Each SIVGA product I have tested has left me impressed. The brand consistently delivers premium features at a more affordable price point compared to its more established competitors, all while maintaining an attractive wooden design across its range.

The latest addition to the lineup is the SIVGA Lyrebird, a unique pair of in-ear monitors (IEMs) that stand out thanks to their quad-driver design. Featuring a 10 mm polymer composite dynamic driver, a balanced armature driver, a micro planar driver, and a 9.2 mm multilayer piezoelectric ceramic driver, the Lyrebird offers a sophisticated sound profile. Surprisingly, despite its advanced driver configuration, the Lyrebird is priced at a reasonable £124.

The packaging includes a high-quality leather hard case, similar to the Nightingale PRO, making it convenient to carry around. Each earpiece features a CNC-machined aluminium alloy shell with a unique stabilised wood faceplate, ensuring a one-of-a-kind aesthetic for each unit. The compact and lightweight design of the shells, combined with the high-quality cable made of Furukawa OFC, silver-plated copper, and gold-plated silver-copper conductors, enhances comfort and durability. Additionally, the inclusion of multiple ear tip sizes allows for a customized and secure fit without the need for additional purchases.

Moving on to the sound quality of the SIVGA Lyrebird:

In my testing, I used the Khadas Tea Pro DAC for mobile use and the Fosi Audio K7 for desktop use. The Lyrebird’s driver design consists of a 10 mm polymer composite dynamic driver, a balanced armature driver, a micro planar driver, and a piezoelectric ceramic driver, each contributing to a cohesive and balanced sound profile. The transition between the drivers is seamless, resulting in a harmonious presentation without any driver overpowering the others. The dynamic driver’s bass gains elasticity and rhythm after a short burn-in period, enhancing the overall listening experience.

– Bass:
The bass on the Lyrebird is well-controlled and elastic, providing a balanced low end without overpowering the mids. The mid-bass offers a gentle lift, adding body to the sound, while the sub-bass remains restrained. This tuning is ideal for those who prefer a more natural and cohesive sound without excessive emphasis on the low end.

– Mids:
The mid-range clarity on the Lyrebird is excellent, thanks to the balanced armature driver. Vocals and instruments are presented with neutrality and naturalness, maintaining a composed sound without being overly forward. The upper mids are subtly elevated, contributing to a detailed and clear mid-range performance.

– Treble:
The treble response on the Lyrebird is detailed and airy, courtesy of the micro planar driver and piezoelectric ceramic driver. The extension into the higher frequencies is smooth, adding sparkle and air to the sound without being harsh. While the treble is pronounced, it remains balanced and shimmering, making it suitable for extended listening sessions without causing fatigue.

– Vocals:
The vocals on the Lyrebird shine, offering glossy and natural male vocals and detailed female vocals. The balanced armature driver ensures clarity and detail, placing vocals slightly forward in the mix without overpowering other elements. Whether listening to acoustic or pop tracks, the vocals stand out with exceptional clarity and presence.

In terms of pricing and alternatives, the SIVGA Lyrebird is available for £124, offering a competitive value for its performance and build quality. Other IEM options from SIVGA include the SM100 Dynamic Driver IEMs (£33), Que Beryllium-Plated Dynamic Driver IEMs (£59), Nightingale Planar Magnetic IEMs (£211), and Nightingale PRO (£224). The Simgot SuperMix 4, which features a similar quad-driver design, is available for £137 on Ali Express or £160 on Amazon. Additionally, alternatives such as the Blon A6 and Dita Audio Project M2 provide compelling options for those seeking a similar sound profile at different price points.

In conclusion, the SIVGA Lyrebird is a noteworthy addition to the brand’s lineup, offering a unique quad-driver configuration with a cohesive and refined sound signature. The build quality, premium accessories, and detailed sound reproduction make it a compelling choice for audiophiles and music enthusiasts. While the restrained sub-bass and slightly bright treble may not appeal to all listeners, the overall performance of the Lyrebird at its price point is commendable. Whether you prioritize vocal clarity, detailed treble, or a clean and neutral sound profile, the SIVGA Lyrebird presents a strong option for discerning listeners.
