Designed to deliver room‑filling sound with deep, punchy low end, it features 60mm drivers and Oraimo’s proprietary HavyBass™ technology.

The speaker supports multiple playback sources: Bluetooth 5.0, FM radio, AUX input, and USB flash drive. With TWS (True Wireless Stereo) pairing, you can connect two Boom speakers together for a wider, more immersive stereo soundstage. A 3,600mAh battery provides up to 6 hours of playtime with lights on and 7 hours with lights off. The built‑in microphone and dedicated line‑in mic input make it suitable for karaoke or hands‑free calls. The speaker is IPX5 splash‑resistant, features a retractable leather‑style handle for easy carrying, and comes in a compact design measuring 360×132×133 mm.

2. Key Specifications at a Glance

3. 30W Powerful Sound with 60mm Drivers and HavyBass™ Technology

The Oraimo Boom OBS-75D delivers 30W of powerful audio through a pair of 60mm dynamic drivers. The large driver size allows for greater air movement, producing louder volume and stronger bass than smaller portable speakers. The HavyBass™ technology further enhances low‑frequency response, adding punch and depth to kick drums, bass guitars, and electronic synth lines. This makes the speaker ideal for bass‑heavy genres like hip‑hop, EDM, dubstep, and rock. Even at high volumes, the sound remains clear with minimal distortion. The speaker can easily fill a small to medium‑sized room, backyard, or campsite. Whether you are listening indoors or outdoors, the Oraimo Boom provides an energetic, room‑filling sound experience.

4. Dynamic RGB Light Effects – Four Modes to Match the Beat

The Oraimo Boom OBS-75D features a built‑in RGB LED light system with four dynamic modes that respond to your music. The lights are located behind the front grille and can be controlled via a dedicated button on the speaker. Modes typically include:

• Solid colour – Choose a single colour (red, green, blue, etc.).

• Breathing – The light slowly fades in and out.

• Cycle – Automatically transitions through multiple colours.

• Music sync – The lights pulse, flash, and change colour in real time with the beat of the music.

The RGB effects create a party atmosphere, making the speaker a visual focal point for any gathering. You can also turn the lights off to save battery when not needed.

5. Multiple Playback Sources – Bluetooth, FM Radio, AUX, USB

The Oraimo Boom OBS-75D is incredibly versatile, supporting four distinct playback modes:

• Bluetooth 5.0 – Stream wirelessly from any Bluetooth‑enabled device (smartphone, tablet, laptop). Range is up to 10 metres with stable connection.

• FM Radio – Listen to local FM radio stations. The speaker can scan for available stations and save presets.

• AUX Input – Connect non‑Bluetooth devices using a 3.5mm audio cable (not included). This is perfect for older MP3 players, laptops, or gaming consoles.

• USB Port – Insert a USB flash drive loaded with MP3 or WMA files for direct playback. The speaker will read and play music from the drive.

You can switch between modes using the physical buttons on the top panel of the speaker. This variety ensures you can always play music, even without a smartphone or when you want to conserve your phone’s battery.

6. TWS Pairing – Connect Two Boom Speakers for Stereo Sound

A standout feature of the Oraimo Boom OBS-75D is TWS (True Wireless Stereo) pairing. By pressing the TWS button on two compatible speakers, you can pair them wirelessly. One speaker will serve as the left channel, the other as the right channel, creating a true stereo soundstage. This doubles the power and provides a wider, more immersive audio experience, ideal for parties, outdoor movies, or large gatherings. TWS pairing works with any two OBS-75D units (no additional cables required). Once paired, you can control both speakers simultaneously from your Bluetooth device.

7. Battery Life – 3,600mAh with up to 7 Hours of Playtime

The Oraimo Boom OBS-75D is powered by a 3,600mAh rechargeable battery, providing:

• Up to 6 hours of playtime with RGB lights on.

• Up to 7 hours of playtime with RGB lights off.

The battery life is sufficient for a full day of outdoor use or an evening party. A full charge takes approximately 3‑4 hours via the included USB‑C cable (charging port type not specified, but likely micro‑USB or USB‑C). The speaker also has LED battery indicators to show remaining power. For longer events, you can turn off the lights to extend runtime.

8. Karaoke and Hands-Free Calls – Built-in Mic and Line-in Microphone Support

The Oraimo Boom OBS-75D includes two microphone features:

• Built‑in noise‑canceling microphone – For hands‑free calling. When a call comes in, the music automatically pauses, and you can press the dedicated button to answer. The microphone picks up your voice clearly, reducing background noise.

• External microphone input (line‑in) – A 3.5mm jack on the speaker allows you to connect a standard wired microphone (not included). This turns the Boom into a karaoke machine – perfect for parties, family gatherings, or even small performances. You can sing along to music played via Bluetooth, USB, or FM radio while the microphone audio is mixed in real time. The volume of the microphone can be adjusted independently on the speaker.

This karaoke functionality is rare in speakers at this price point and adds significant value for entertainment.

9. Portable Design – Retractable Leather‑Style Handle and IPX5 Splash Resistance

The Oraimo Boom OBS-75D is designed for portability. It features a retractable leather‑style handle that folds flush into the top of the speaker when not in use. This handle is comfortable to grip and makes it easy to carry the speaker to the beach, park, or a friend’s house. The dimensions of 360×132×133 mm are compact enough to fit in a backpack or car trunk, yet the speaker is large enough to produce powerful sound.

The speaker is rated IPX5, meaning it is splash‑resistant. It can withstand light rain and splashes from any direction, making it suitable for outdoor use. However, some reviewers note that the lighting components can be sensitive, so it is best to avoid heavy water exposure or submersion. Keep the speaker away from pools, showers, or heavy downpours to ensure longevity.

• Oraimo Boom OBS-75D portable speaker unit

• Charging cable (USB‑A to micro‑USB or USB‑C)

• AUX cable (3.5mm)

• User manual

Note: A wall charger and microphone are not included. For karaoke, purchase a standard 3.5mm wired microphone separately.
