Oraimo OEB-E30D Shark 4 Neckband
The Oraimo OEB-E30D Shark 4 Neckband delivers deep bass and long wireless listening. It supports Bluetooth 5.3 and two sound modes. Moreover, its 120mAh battery provides up to 20 hours of playtime.
Choose Your Preferred Sound
The Shark 4 provides Normal and HavyBass sound modes. Therefore, you can choose the sound that suits your content.
Normal mode provides a balanced sound for calls and general listening. In contrast, HavyBass mode adds more power to low tones.
Press the M button once to change the sound mode. As a result, you can adjust the audio without using an app.
Enjoy Deeper Bass
Oraimo uses its second-generation HavyBass system in the Shark 4. Therefore, the neckband produces deeper and stronger bass.
This sound works well with music that depends on strong low tones. For example, it can add more impact to dance and workout playlists.
However, sound quality also depends on the earbud fit. Therefore, select ear tips that fit your ears correctly.
Listen for Up to 20 Hours
The 120mAh battery provides up to 20 hours of playtime. Consequently, you can listen throughout the day without frequent charging.
However, battery life depends on volume and connection conditions. Game mode may also use more power during operation.
The Type-C charging input provides a modern charging connection. Moreover, the common port makes finding a suitable cable easier.
Stable Bluetooth 5.3 Connection
Bluetooth 5.3 connects the neckband to supported wireless devices. Therefore, it provides a fast and stable link.
The connection works within a range of up to 10 metres. However, walls and other wireless signals can reduce this distance.
The Shark 4 can also connect to two devices. As a result, you can switch between a phone and another supported device.
Low-Latency Game Mode
Game mode reduces the delay between video and sound. Therefore, actions and audio remain better matched during supported games.
Press and hold the M button to activate this mode. Likewise, press and hold the same button to return to normal mode.
This feature also helps when watching fast-moving video. However, the final delay depends on the connected device and application.
IPX5 Sweat and Splash Protection
The IPX5 rating protects the neckband against sweat and light water splashes. Therefore, you can use it during workouts and light rain.
However, IPX5 does not support water immersion. Avoid swimming, showering or placing the neckband under running water.
Moreover, dry the earphones after exercise. This simple step helps keep the charging port and controls clean.
Magnetic Earbud Storage
Each earbud contains a built-in magnet. Therefore, the earbuds can attach when you are not listening.
The magnetic design keeps them together around your neck. As a result, the wires remain more organized during storage.
Moreover, this feature reduces loose movement while you walk. However, the magnets do not turn the neckband off automatically.
Simple Button Controls
The control panel lets you manage music, calls and volume. Therefore, you can operate the neckband without reaching for your phone.
The buttons support several actions:
- Play or pause music
- Answer or end calls
- Reject incoming calls
- Increase or reduce volume
- Move to the next or previous track
- Switch between the two EQ modes
- Turn game mode on or off
