The Linsoul Kiwi Ears Spark Earbuds are designed for users who want to stay aware of their surroundings without sacrificing sound quality. Built around an open-ear wireless (OWS) design, these earbuds target outdoor enthusiasts, commuters, and fitness users who need comfort, safety, and reliable performance throughout the day. With Bluetooth 5.2 connectivity, a lightweight silicone earhook design, and a focus on clear, balanced audio, the Kiwi Ears Spark aim to stand out in the growing open-ear earbuds market.
The Spark earbuds use an open-ear structure that allows ambient sounds to pass through naturally. This makes them ideal for running, cycling, or commuting, where situational awareness is essential. You can enjoy music or calls without feeling isolated from your environment.
Each earbud is crafted with ultra-soft liquid silicone combined with a memory-steel earhook. This design ensures a secure yet flexible fit that adapts comfortably to different ear shapes. Weighing just 8.7 grams per earbud, they feel almost unnoticeable during long listening sessions or workouts.
The Kiwi Ears Spark are equipped with a large 17x12mm dynamic driver, delivering a sound profile that is rich and engaging. Bass comes through with satisfying depth, mids remain clean and natural, and highs stay vibrant without sounding harsh, especially impressive for an open-ear design.
Touch-sensitive controls allow you to manage playback, adjust calls, and activate voice assistants like Siri with simple taps. The controls are responsive and intuitive, reducing the need to constantly reach for your phone.
On a single charge, the earbuds offer up to 7 hours of playback, while the charging case extends total usage to around 21 hours. The earbuds recharge fully in under 1.5 hours, making them convenient for users with active schedules.
Powered by the QCC3040 chipset, the Spark earbuds support SBC, AAC, and aptX codecs. This ensures stable connections, minimal latency, and high-quality audio performance across Android, iOS, and other Bluetooth-enabled devices.
With an IPX5 rating, the Kiwi Ears Spark can handle sweat, splashes, and light rain. This makes them reliable companions for gym workouts, outdoor runs, and travel.
The Linsoul Kiwi Ears Spark Earbuds are priced at $75.00 in the US. They are available on Amazon and other major online platforms.

In everyday use, the Kiwi Ears Spark deliver an impressive balance of comfort, sound clarity, and usability. The open-ear design works exceptionally well for users who want to stay connected to their surroundings, and the sound quality comes remarkably close to traditional in-ear earbuds. Stereo separation feels natural, and calls remain clear thanks to the single-microphone ENC system.
Comfort is one of the strongest aspects of these earbuds. Their flexible earhook design makes them some of the most comfortable open-ear earbuds available, even during long listening sessions. Battery life also holds up well in real-world usage, with around five hours of playback still leaving noticeable charge remaining.
However, the charging case design is unusual and may not appeal to everyone. The partially open top can feel impractical, especially when pulling the case from a pocket, and it raises concerns about accidental opening or snagging. While the sound quality is among the best in its category, the price is higher than many competing open-ear earbuds, some of which offer decent performance at nearly half the cost.
Despite these drawbacks, the Spark earbuds pair quickly, feel incredibly lightweight, and deliver a listening experience that feels natural rather than intrusive. With a more conventional charging case, they would easily compete at the very top of their category.
If sound quality and comfort are your top priorities in an open-ear earbud, the Linsoul Kiwi Ears Spark are a strong choice. They are especially suitable for runners, commuters, and users who value awareness and long-term comfort. However, budget-focused buyers or those who prefer a traditional charging case design may want to consider alternatives.
The Linsoul Kiwi Ears Spark Earbuds deliver one of the best sound experiences available in the open-ear wireless category. Their lightweight fit, premium audio tuning, and reliable connectivity make them a pleasure to use daily. While the price and charging case design may not suit everyone, users who prioritize comfort and audio clarity will find the Spark earbuds a worthy investment.
