1. Introduction
The oraimo OpenSnap (OPN-373) is a pair of clip-on, open-ear true wireless earbuds designed for users who need situational awareness while enjoying high-quality audio. Unlike traditional in-ear or over-ear headphones, the OpenSnap earbuds sit outside the ear canal, using a unique clip-on “C‑bridge” design with titanium‑alloy memory wire that gently secures around your ear. This design allows you to hear your surroundings – traffic, announcements, or conversations – making them ideal for running, cycling, office work, or any outdoor activity where safety and awareness are paramount. Despite the open-ear format, the oraimo OpenSnap delivers impressive audio quality thanks to a 10.8mm dynamic driver and oraimo’s HavyBass™ technology, which enhances bass response. With up to 26 hours of total battery life (6 hours per charge + 20 hours from the case), Bluetooth 5.4, dual microphones with AI Call Noise Cancellation, and an IPX4 water‑resistant rating, the OpenSnap is a versatile and practical choice for active lifestyles.

3. Clip-On Open-Ear Design – Titanium-Alloy C-Bridge for Comfort and Security
The oraimo OpenSnap features a clip-on “C‑bridge” design made of titanium‑alloy memory wire. This flexible yet durable material conforms to the shape of your ear, providing a secure, comfortable fit that stays in place during vigorous activities. Unlike traditional earbuds that insert into the ear canal, the OpenSnap rests outside the ear, with the speaker driver positioned near your ear opening. This design allows you to hear ambient sounds – traffic, bike bells, or coworkers – while still enjoying your music or podcasts. The open-ear format also eliminates ear fatigue and the “plugged” sensation, making the oraimo OpenSnap ideal for extended wear. The clip‑on mechanism ensures the earbuds won’t fall off, even during running or jumping.
4. HavyBass™ Technology with 10.8mm Driver – Rich Bass in an Open-Ear Format
One challenge of open‑ear earbuds is delivering satisfying bass. The oraimo OpenSnap overcomes this with a 10.8mm dynamic driver paired with oraimo’s proprietary HavyBass™ technology. This combination enhances low‑frequency response, delivering punchy bass that adds energy to your music without completely blocking outside sounds. While the bass won’t match that of sealed in‑ear monitors, it is remarkably robust for an open‑ear design. Mids and highs remain clear, making the OpenSnap suitable for a wide range of genres, from pop and rock to podcasts and audiobooks.
5. 26 Hours Total Battery Life – 6h Earbuds + 20h Charging Case
The oraimo OpenSnap offers up to 26 hours of total battery life. The earbuds themselves provide 6 hours of continuous playback on a single charge. The compact charging case holds an additional 20 hours of power, giving you three to four full recharges before needing to plug in the case. This is ample for a full day of use or several days of moderate listening. The case charges via USB‑C (cable included, wall charger not included). Fast charging details are not specified, but typical for this class.
6. Bluetooth 5.4 – Stable Wireless Connection
The oraimo OpenSnap uses Bluetooth 5.4 (some regional variants may list 5.3). Key benefits include:
Fast, stable pairing – Connect quickly after initial setup.
Extended range – Maintain a connection up to 10 metres (33 feet) from your device.
Improved power efficiency – Contributes to the long battery life.
Reliable connectivity – Fewer dropouts, even in environments with many wireless devices.
The earbuds support standard Bluetooth profiles and will automatically reconnect to your last paired device when removed from the case.
7. AI Call Noise Cancellation with Dual Microphones – Clear Calls Anywhere
The oraimo OpenSnap is equipped with dual microphones that use AI Call Noise Cancellation technology. This system isolates your voice from background noise – wind, traffic, 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. This is a crucial feature for remote workers, outdoor runners who take calls, or anyone who uses earbuds for virtual meetings.

8. IPX4 Water and Sweat Resistance – Workout-Ready
The oraimo OpenSnap are rated IPX4, meaning they are protected against sweat and splashes from any direction. This makes them ideal for:
Jogging or running – No worry about perspiration.
Gym workouts – Resistance to sweat.
Light rain – Splashes won’t damage the earbuds.
9. Physical Buttons – No Accidental Touches
Unlike many touch‑controlled TWS earbuds, the oraimo OpenSnap feature physical buttons on the earbuds. This prevents accidental touches that could pause your music, skip a track, or hang up a call when you adjust the earbuds or brush against something. The buttons are responsive and easy to locate by feel, allowing you to control playback, volume, and calls without looking.
Typical controls include:
Single press: Play/pause or answer/end call
Double press: Next track or reject call
Triple press: Previous track
Long press: Voice assistant or volume (depending on implementation)
