The Native Union Monocle Speaker represents a fascinating approach to portable audio, challenging conventional thinking about how we consume music on the go. During my testing, I found this unique device from the Hong Kong-based company to be equal parts innovative and polarizing, offering a dual-function design that serves as both a single-ear headphone and a compact speaker with the simple twist of a dial.
Design and Build Quality
The Native Union Monocle Speaker immediately stands out with its distinctive single-ear cup design that defies traditional audio device conventions. As the name suggests, this is literally a monocle for your ears – a single driver housing that can transform from private listening device to public speaker.
I found the build quality to be exceptional for the price point. The standard models feature a matte finish in four appealing colours: Coral Red, Marine Blue, Mint, and Slate. However, the premium variants truly showcase Native Union's attention to detail. The Brushed Black Diamond and Brushed Copper models incorporate an aluminium construction with a grooved finish reminiscent of vinyl records, creating a tactile experience that feels genuinely premium.
The threaded nylon cable deserves particular mention – it's both aesthetically pleasing and functionally superior to typical rubber cables. The inline microphone integrates seamlessly into the design, while the included loop attachment adds practical value for travelers who need to secure the device to bags or clothing.
Audio Performance and Functionality
The Native Union Monocle Speaker's audio performance varies significantly depending on its operational mode. The 40mm driver provides the foundation for both headphone and speaker functionality, though each mode presents distinct characteristics.
In headphone mode, I found the audio quality to be clear and crisp, particularly in the mid and high frequencies. However, bass response feels somewhat constrained – understandable given the single-driver design and lack of sealed acoustic chamber that traditional over-ear headphones provide. The leather cushioning does help with passive noise isolation, but effectiveness depends entirely on how firmly you press the device against your ear.
Switching to speaker mode via the rear dial transforms the experience entirely. Despite its compact size, the Native Union Monocle Speaker produces surprising volume levels that can easily fill a small to medium room. The sound remains clear even at higher volumes, though don't expect the depth and richness you'd get from dedicated speakers.
Connectivity and Smart Features
The Native Union Monocle Speaker offers straightforward connectivity through its 3.5mm jack, making it compatible with virtually any audio source. The inline microphone enables hands-free calling, and I found call quality to be acceptable for casual conversations, though not quite matching dedicated headsets.
One of the most intriguing features is the ability to daisy-chain up to 10 Monocle Speakers together. While I didn't test the full 10-unit configuration, connecting multiple units does create a more substantial soundstage, though at that point you're approaching the cost of proper multi-room audio systems.
Battery Life and Charging
Battery performance on the Native Union Monocle Speaker proved solid during my testing period. I consistently achieved approximately 5.5 hours of playback time, which aligns with the manufacturer's specifications. The included micro-USB charging cable maintains the same premium nylon construction as the audio cable, showing attention to detail throughout the accessory package.
The device arrives pre-charged, allowing immediate use out of the box – a nice touch that eliminates the frustration of waiting for initial charging cycles that plague many portable devices.
Practical Usage and Limitations
The Native Union Monocle Speaker's unique design creates both opportunities and limitations. As a conversation starter and design object, it excels – this is definitely a device that generates interest and discussion. However, practical daily use reveals some inherent constraints.
Using the device as a headphone requires constant manual holding, making it impractical for activities requiring hand mobility. You're essentially trading convenience for the novelty of the dual-function design. The speaker mode proves more practical, particularly for impromptu music sharing or when you need audio in environments where traditional speakers aren't available.
Pricing and Value Proposition
At £39.99 for standard models and £49.99 for the premium finishes, the Native Union Monocle Speaker occupies an interesting position in the portable audio market.
The pricing feels reasonable considering the unique design, premium materials, and build quality. This isn't a device you purchase purely for audio performance – you're paying for innovation, aesthetics, and the conversation-starting factor. As a gift item, the Native Union Monocle Speaker has considerable appeal, particularly for design-conscious individuals who appreciate unique tech accessories.
Final Verdict
The Native Union Monocle Speaker succeeds as a design statement and conversation piece while offering functional, if limited, audio capabilities. It's not going to replace your primary headphones or speakers, but it fills a unique niche for users who value innovative design and occasional audio sharing.
During my testing period, I found myself reaching for the Native Union Monocle Speaker in specific scenarios – small gatherings where I needed to share audio quickly, or situations where traditional speakers weren't practical. The premium build quality and attention to detail justify the asking price, though potential buyers should understand they're purchasing a specialty item rather than a mainstream audio solution.
For design enthusiasts, gift-givers, or anyone seeking a unique addition to their tech collection, the Native Union Monocle Speaker delivers on its promise of being something genuinely different in the crowded portable audio space.
