Product Overview
The Oraimo SpaceBuds 2 OTW-631 are feature-packed true wireless earbuds designed to combine smart AI functionality, long battery life, and immersive audio in a stylish, modern design. Positioned in the mid-range segment, they aim to deliver premium features—like Hybrid Active Noise Cancellation (ANC) and AI-powered tools—at a more accessible price point, making them ideal for everyday users, students, and travelers.
At the core of the SpaceBuds 2 is its AI-enhanced Hybrid ANC system, capable of reducing environmental noise by up to 52dB, helping users focus on music, calls, or work even in noisy environments. The earbuds also include a Transparency Mode, allowing users to stay aware of their surroundings when needed—useful for commuting or outdoor use. The AI system dynamically adapts noise cancellation performance based on the environment, improving overall listening comfort.
Sound performance is driven by 11mm dynamic drivers combined with Oraimo’s HavyBass™ technology, delivering deep bass, balanced mids, and clear highs. The addition of spatial audio enhances immersion, creating a wider, more “live-stage” listening experience. Whether for music, movies, or gaming, the earbuds aim to provide a rich and engaging sound profile.
One of the standout aspects of the SpaceBuds 2 is its AI smart features, which go beyond typical earbuds. These include real-time AI translation, voice prompt customization, transcription, and AI-generated summaries, making them useful not just for entertainment but also for communication and productivity—especially in multilingual or travel scenarios.
Battery life is another strong highlight. The earbuds offer up to 45 hours of total playtime (ANC off) and around 35 hours with ANC on, with up to 11.5 hours on a single charge. Fast charging is also supported, where just 10 minutes of charging provides up to 3 hours of playback, ensuring minimal downtime.
In terms of usability, the SpaceBuds 2 introduce a smart charging case with physical control, allowing users to manage playback or even trigger functions without tapping the earbuds directly. Additional features like dual-device connection, low-latency gaming mode, and IP55 water/dust resistance make them versatile for daily use, workouts, and multitasking.
