Customer Review Summary
[META]Test of Positive Grid Spark Neo Core headphones with amp modelling, Bluetooth, custom drivers and Spark app integration for guitar practice.Introduction
The Positive Grid Spark Neo Core headphones, released in October 2025, combine wireless connectivity, amp modelling, and effects in a closed-back, over-ear design. Priced at £111, this device targets electric and acoustic guitar and bass players seeking a portable, private practice solution. This review assesses the build, sound quality, and usability with the integrated Spark app.
Design and Build
The Spark Neo Core sports a lightweight 363-gram frame with padded ear cups that fit comfortably over the ears. The adjustable headband accommodates larger head sizes without pressure points, making extended sessions feasible. Its closed-back construction helps with noise isolation, thanks to 40 mm custom drivers, ensuring minimal sound leakage.
Connectivity is wireless via Bluetooth 5 with a range of approximately 5 metres. Instrument input is provided through a 6.35 mm jack, though the cable is sold separately. USB-C fast charging supports battery life ranging between 6 and 8 hours depending on usage. The compact dimensions (180 x 195 x 81 mm) contribute to portability.
Features and Functionality
A significant draw of the Spark Neo Core is its full integration with the Spark app available on iOS and Android. The app offers access to 33 amplifier models and 43 effects, enabling users to shape their tone extensively. AI Tone Creation can generate customised sounds based on user input, simplifying tone design.
The headphones have onboard controls to switch among four presets, with separate volume controls for guitar input and backing track playback. Bluetooth allows streaming of backing tracks while simultaneously playing through the wired instrument input. This dual-audio approach encourages jamming along with music.
Amp and Effect Modelling
- 33 different amplifier simulations tailored to various guitar styles
- 43 effects including modulation, distortion, and reverb
- AI-driven tone generation facilitates creating unique sounds quickly
- Access to ToneCloud presets from other users for inspiration
Performance in Use
Initial setup is straightforward. Installing the Spark app, pairing via Bluetooth, and connecting the guitar cable gets the user ready promptly. The amp models and effects respond well to playing nuances, providing a realistic experience for both electric guitar and bass.
Sound quality for both instrument input and backing audio is clear and well-balanced, benefiting from the noise-isolating ear cups. Experimentation with different presets and AI-generated tones reveals the versatility of the system in accommodating various musical genres and playing styles.
The separate volume controls for guitar and backing tracks enable fine-tuning during practice. The 6-hour battery life is adequate for typical practice sessions, with quick USB-C charging minimising downtime.
Limitations and Considerations
While the headphones are excellent for private practice, they do not support jam sessions with other Spark devices when used as a headset. Additionally, the lack of an instrument cable in the package requires an extra purchase. Users should also consider the closed-back design might cause slight heat buildup in warmer environments.
Conclusion
The Positive Grid Spark Neo Core offers a compelling solution for guitar enthusiasts wanting portable, private practice with a comprehensive suite of amp modelling and effects. Its integration with the Spark app and AI tone creation stands out, empowering quick and effective sound design. Comfortable build and reliable Bluetooth connectivity complement the feature set. At £111, it delivers excellent value for those serious about practising their instrument discreetly without compromise on sound or functionality.
