PRUNUS J-999 Retro Bluetooth Speaker Review

Nostalgic Design & Portability
The J-999’s retro wooden box look and metal accents give any room a classic vibe. It even has a little leather handle so you can grab it like a pocket radio. This makes it both decorative and practical.
You can slip it into a bag or hang it on a hook and always have music on hand. Its build feels solid yet lightweight (only about 0.44 lb), so you can tote it from the kitchen to the campsite without effort. The charming design also makes it a unique gift for friends or family who love vintage style.
Multiple Playback Options
No matter how you like to listen, the J-999 has you covered. It supports Bluetooth 5.0 for wireless streaming, and also has slots for a microSD (TF) card and a USB stick. You can plug in an AUX cable to play from a laptop or MP3 player. The speaker even has a built-in FM radio tuner.
In practice this means you can enjoy music any way you want: wirelessly from your phone, by inserting a music card, or by tuning into local radio. One reviewer notes it “supports BT, audio cable, SD card, and USB drive… there is so much to like here”. All these inputs are easy to access, so swapping sources is a breeze.
Bluetooth 5.0 & Hands-Free Calling
This speaker uses the latest Bluetooth 5.0 standard. That means quick, stable pairing with your phone or tablet. Once paired, the music plays smoothly with hardly any dropouts. You can keep enjoying tunes even as you move around the house.
There’s also a built‑in microphone, so you can answer phone calls through the speaker. A single button lets you switch to hands‑free mode easily.
In short, the Bluetooth connection is reliable, and you can chat on calls through the speaker without touching your phone.
Rich Sound & Easy Controls
For its size, the J-999 delivers surprisingly full sound. It has a 3W driver and a passive bass radiator in back, which helps music fill a small room. Users say the sound is “great for a speaker this small”, with no obvious distortion at normal volumes.
On top, a big volume knob gives you precise control. You can even turn the dial all the way down before power-on to avoid sudden blasts. Reviewers praise this feature: “A huge plus is the rotary volume control…it allows an absolutely silent power on”.
In short, you get nice, warm audio and a dial that makes it easy to start quiet or get loud gradually.
Battery Life & Usage
The Prunus J-999 runs on a built-in rechargeable battery. It offers about 7 hours of playtime on a moderate volume (50%). That’s enough for a few movie binges, a day at work, or a night of steady music. Charging takes around 7 hours via the included USB cable.
The battery isn’t huge, so if you listen all day at max volume you may need a mid-day recharge. Still, for short trips or office use it holds up well. Its low weight and small size make it super travel-friendly – toss it in a daypack and you’ve got music on the go.
