The Kiwi Ears Spark is a stylish and thoughtfully engineered open-ear Bluetooth headset designed with active lifestyles in mind. With a focus on comfort, clarity, and ambient awareness, the Spark delivers a unique listening experience—especially for users who value situational awareness and extended comfort.
Kiwi Ears Spark Review: Design & Build Quality
Right out of the box, the Kiwi Ears Spark impresses with its distinctive design and premium materials. The headphones feature a matte silicone body paired with metallic accents, giving them a solid, high-end feel. The charging case, with its open, half-metal construction and elegant champagne gold lid, is both eye-catching and robust. Though the open lid design may invite dust over time, it certainly adds character and durability.
The headphones themselves feel sturdy and well-built—there are no creaks or signs of cheap plastic here. The ear hooks and outer casing are finished with a smooth matte silicone that feels soft against the skin. Overall, the Spark strikes a perfect balance between aesthetics and durability.
Fit & Comfort
We found the Spark to be exceptionally comfortable during shorter sessions. Its open-ear design rests gently on the outer ear, rather than inside the ear canal, making it an ideal choice for those who find in-ear models intrusive. Over time, however, the ear hooks may cause minor discomfort, especially where they meet the front of the ear near the helix. Still, the lightweight nature and ergonomic shape make the Spark easy to wear for most of the day.
Audio Performance
Sound-wise, the Spark leans toward a bright, mid-centric profile. It excels in vocal clarity and high-frequency detail, making it a great choice for podcasts, calls, and genres that benefit from crisp mids and treble. However, due to the open-ear design, bass performance is limited. Without a seal around the ear canal, the Spark struggles to reproduce deep low frequencies. This isn’t a design flaw—just a trade-off of open-ear headphones.
Volume levels are generally adequate, though users with unique ear shapes may find that slight positioning changes can significantly affect sound quality. When the speakers are closer to the ear canal, both clarity and bass presence improve noticeably.
Despite the reduced low-end, the Spark surprises with its spacious soundstage. There’s a pleasant sense of air and stereo separation, especially with vocals and acoustic instruments. For critical listening or bass-heavy genres, traditional in-ear monitors would still be preferable. But for casual listening and everyday use, Spark performs admirably.
Performance in Real-World Use
In our day-to-day use, especially in a professional setting, Spark proved to be a reliable companion. Calls and video meetings were handled with ease, thanks to the ENC (Environmental Noise Cancellation) mic, which kept voice communication clear and focused. The open design allowed us to stay connected to our surroundings, making it ideal for office environments.
The Bluetooth 5.2 connection was stable throughout, and the multi-touch controls were intuitive and responsive. With support for SBC, AAC, and aptX codecs, we experienced minimal latency and solid audio quality across multiple devices.
The charging case features a three-color LED indicator, making it easy to monitor battery levels. Battery life was sufficient to get through a full workday, and the IP45 rating offered peace of mind during commutes or workouts.

Kiwi Ears Spark Review: Final Thoughts
