1. Introduction

The oraimo SpaceBuds Air (OTW-324S) are true wireless earbuds designed for users who prioritise comfort, immersive audio, and smart features. Unlike traditional in-canal earbuds, the SpaceBuds Air feature a lightweight half-in-ear design that rests gently on the outer ear, making them comfortable for extended wear – perfect for long calls, podcasts, or all-day listening.

With up to 38 hours of total battery life (6.5 hours on the earbuds plus 31.5 hours from the charging case), fast charging (10 minutes gives 2 hours of playtime), Sound360 Spatial Audio, and HavyBass™ deep bass, these earbuds deliver an exceptional audio experience. Bluetooth 5.4 ensures a stable connection, and a dedicated Game Mode provides low-latency audio for gaming.

The AI call noise cancellation with dual microphones filters out background noise for crystal‑clear calls. A standout feature is the Smart Earbud Finder via the oraimo sound app – trigger a sound cue to locate misplaced earbuds. The charging case also includes an anti‑lost braided lanyard to help secure it and prevent loss, and dual‑device connectivity allows seamless switching between your phone and laptop. Rated IPX4 water‑resistant, the SpaceBuds Air are sweat‑proof for workouts.

2. Lightweight Half-In-Ear Design – All-Day Comfort

The oraimo SpaceBuds Air feature a half-in-ear design (also called semi-in-ear). Unlike deep‑insertion in‑canal earbuds, the SpaceBuds Air rest gently on the outer ear without creating a tight seal. This design is ideal for users who find traditional in‑ear earbuds uncomfortable or who need to remain aware of their surroundings (e.g., while walking, cycling, or working in an office).

The lightweight construction (weight not specified, but notably light) ensures you can wear them for hours without ear fatigue. The open design also reduces the “plugged” sensation, making them perfect for long calls, podcasts, and background music.

3. 38 Hours Total Battery Life with Fast Charging

The oraimo SpaceBuds Air offer an impressive 38 hours of total battery life – 6.5 hours from the earbuds themselves plus 31.5 hours from the charging case. This allows you to listen for several days without reaching for a charger.

The case supports fast charging: just 10 minutes of charging gives you 2 hours of playtime, perfect for a quick top‑up before a workout or commute. A full charge of the case takes a few hours via USB‑C.

4. Sound360 Spatial Audio and HavyBass™ – Immersive 3D Sound

The oraimo SpaceBuds Air are equipped with Sound360 Spatial Audio, which transforms standard stereo sound into a three‑dimensional listening experience. Instruments and vocals feel like they are coming from around you – front, back, and sides – creating a cinematic soundstage. This is especially effective for movies, live music, and open‑world games.

HavyBass™ technology delivers deep, punchy bass without muddying the mids and highs, adding energy to hip‑hop, EDM, and rock. The combination of Sound360 and HavyBass™ provides an immersive, engaging audio experience.

5. Bluetooth 5.4 with Game Mode – Stable, Low-Latency Gaming

The oraimo SpaceBuds Air use Bluetooth 5.4, the latest standard for wireless audio. Benefits include:

• Faster pairing – Connect quickly after initial setup

• Stable connection – Fewer dropouts, even in crowded environments

• Improved power efficiency – Contributes to the 38‑hour total battery life

• Extended range – Maintain a connection up to 10 metres (33 feet) from your device

A dedicated Game Mode reduces audio latency to near‑zero, ensuring that in‑game sounds are perfectly synchronised with the on‑screen action. Activate Game Mode via the oraimo sound app or a tap sequence for an immersive gaming experience on mobile devices.

6. AI Call Noise Cancellation – Crystal-Clear Calls Anywhere

The oraimo SpaceBuds Air feature dual microphones with AI call noise cancellation technology. This system isolates your voice from background noise – such as traffic, wind, office chatter, or gym sounds – ensuring that the person on the other end hears you clearly and naturally.

Even in moderately noisy environments, your calls remain professional and intelligible. This makes the earbuds excellent for remote work, video conferences, and phone calls on the go.

7. Smart Earbud Finder – Never Lose Your Earbuds Again

A standout feature of the oraimo SpaceBuds Air is the Smart Earbud Finder integrated into the oraimo sound app. If you misplace one or both earbuds, you can open the app and trigger a sound cue from the earbuds.

The earbuds will emit a loud beep (even if they are not currently connected to your phone, as long as they have battery), helping you locate them under a couch cushion, in a backpack, or another room. This feature is a lifesaver for anyone who frequently loses small earbuds.

8. Anti-Lost Lanyard – Secure Your Charging Case

The charging case of the oraimo SpaceBuds Air comes with a braided anti‑lost lanyard. You can attach the lanyard to your bag, belt loop, or wrist, preventing the case from being accidentally dropped or left behind.

This is especially useful for travellers, students, and active users who are always on the move. The lanyard is durable and adds a touch of style.

9. Dual-Device Connectivity – Seamless Switching

The oraimo SpaceBuds Air support dual‑device connectivity, allowing you to pair the earbuds to two devices simultaneously. For example, you can connect to your laptop for a Zoom meeting and your smartphone for music, and seamlessly switch between them without manually disconnecting and reconnecting.

When a call comes in on your phone, the earbuds automatically prioritise the call, then resume audio from your laptop afterwards. This is a huge productivity boost for multitaskers.

10. IPX4 Water Resistance – Sweat-Proof for Workouts

The oraimo SpaceBuds Air are rated IPX4 water‑resistant, meaning they are protected against sweat and splashes from any direction. This makes them ideal for:

• Intense workouts – No need to worry about perspiration

• Running or cycling – Light rain won’t damage the earbuds

However, they are not designed for swimming or submersion. The IPX4 rating ensures durability during daily active use.
