The Shure SE846 remains a compelling flagship IEM for listeners who value bass quality, tuning flexibility.
Prices last checked June 2026
Overview
The Shure SE846 is a flagship universal in-ear monitor that uses four dedicated drivers per earpiece with a proprietary low-pass filter system that delivers exceptional bass extension and a uniquely customizable sound signature through interchangeable nozzle inserts. Released in 2013 at $999 and now selling at $899, the SE846 was Shure’s first foray into multi-driver balanced armature IEMs and remains a benchmark for build quality and tuning flexibility in the premium universal IEM market. It competes directly with the Campfire Audio Andromeda and 64 Audio U Series, offering a distinctly more modular approach to sound customization.
Design & Build
The SE846 features a transparent polycarbonate shell that reveals the internal driver and crossover arrangement, with a low-profile over-ear design that uses a malleable wireform fit to secure the cable behind the ear for stable positioning during active use. The build quality is exceptional, with a durable transparent housing that allows visual inspection of the internal components and a robust MMCX connector system that accepts standard Shure cables and aftermarket alternatives. The most distinctive design feature is the interchangeable nozzle system: a removal tool allows the user to physically swap the metal sound nozzle between four frequency response filters: balanced (neutral), warm (enhanced bass), bright (enhanced treble), and extended (full-range emphasis). The included fit kit provides Soft Flex silicone sleeves, foam sleeves, Comply foam tips, triple-flange sleeves, and yellow foam sleeves in multiple sizes to ensure a secure acoustic seal.
Performance
The four-driver array uses a dedicated low-pass filter design for the woofer driver that provides genuinely extended sub-bass response down to 15 Hz, a rarity in balanced armature IEMs that typically struggle with bass extension and impact. The standard balanced nozzle delivers a warm, smooth presentation with excellent coherence between the four drivers, avoiding the disjointed crossover behavior that plagues many multi-driver IEMs. Bass is full-bodied and articulate with good texture, the midrange is natural and detailed with a slight warmth that makes vocals sound rich and present, and the treble is smooth and non-fatiguing with good extension but limited air and sparkle compared to modern hybrid IEMs in a similar price range. Soundstage width is above average for a universal IEM, with good depth and imaging that places instruments in a believable three-dimensional space, though the presentation remains inherently intimate as expected from an IEM.
Features
The interchangeable nozzle system is the SE846’s defining feature, offering genuine audible variation between the four filters that allows listeners to tailor the frequency response to their preferences or recording material without any electronic processing. The passive noise isolation is exceptional, blocking up to 37 dB of ambient noise through the combination of deep-fitting design and included foam tips, making these effective for stage monitoring and travel use without active noise cancellation. The detachable cable system with MMCX connectors is standard on newer revisions, supporting both the included 3.5mm cable and the optional RMCE-BT2 Bluetooth adapter or True Wireless Secure Fit Adapter for wireless operation. The ShurePlus PLAY app on newer versions offers a hardware EQ with adjustable parameters, though the SE846 itself is a purely passive IEM that requires no batteries or electronics to function.
Pros
-
Genuinely customizable sound signature through the four interchangeable nozzle filters (balanced, warm, bright, extended) that provide audible variation without any electronic processing or signal degradation, offering exceptional flexibility for different listening preferences and genres.
-
Excellent bass extension and quality from the dedicated woofer driver with low-pass filter design, delivering sub-bass response that is rare in balanced armature IEMs and competes with hybrid and dynamic driver alternatives.
-
Outstanding passive noise isolation of up to 37 dB, making the SE846 effective for stage monitoring, travel, and noisy environments without the need for active noise cancellation.
-
Exceptional build quality with transparent polycarbonate shells, robust MMCX connectors, comprehensive fit kit, and serviceable components that can be maintained and replaced as the cable or tips wear out.
Cons
-
The treble is rolled off and lacks sparkle and airiness compared to modern hybrid and electrostatic IEMs at the same price point, making the SE846 sound somewhat dark and less resolving in the upper frequencies.
-
The interchangeable nozzle system is difficult to operate in practice, requiring significant effort to remove the factory-installed foam tips and swap the tiny metal nozzle filters without damaging the components or losing the tool.
-
At $899, the SE846 is priced against competitors that offer more drivers, more extended treble response, and more modern tuning, making it a dated design in some respects despite its continued relevance.
-
The stock cable has noticeable microphonics (cable noise transmitted to the ear), and the over-ear wireform fit can be uncomfortable for some users during extended wear.
Category Context
The Shure SE846 occupies a unique position in the flagship universal IEM market as one of the few models offering genuinely customizable passive tuning via its interchangeable nozzle system. It competes with the Campfire Audio Andromeda (which uses a 5-BA hybrid design with a more extended treble and wider soundstage at $1,099), the 64 Audio U6t (6-BA with apex internal venting at $999), and the Sennheiser IE 900 (single 7mm XWB driver with tripletuned resonators at $1,399). Where the SE846 excels is bass quality from its dedicated low-pass-filtered woofer - a design that delivers sub-bass extension comparable to hybrid driver IEMs despite using only balanced armatures. The 37 dB passive isolation remains among the best in its class. However, the 11-year-old design shows its age in treble extension and resolution compared to newer multi-BA and electrostatic-hybrid competitors, and the $899 price now places it in a segment with more technically capable options.
Verdict
The Shure SE846 remains a compelling flagship IEM for listeners who value bass quality, tuning flexibility, and bulletproof build quality above outright treble extension and resolution. The interchangeable nozzle system is genuinely useful and delivers real, audible variation, and the bass performance is exceptional for a balanced armature IEM. However, the rolled-off treble and high price relative to newer competition make it a specialist choice rather than a universal recommendation, best suited to those who want modular tuning and are willing to accept a darker, smoother presentation.
