GIECY G300 Portable Voice Amplifier Bluetooth speaker, FM radio, and recorder in one handheld unit
Overview
I find myself in all kinds of meetups, lectures, and tours where I need to speak in front of a crowd. Sure, I could just raise my voice and shout, but there's no real reason to do that anymore, since there are excellent solutions available today, especially when you're out in the field, in the form of voice amplifiers.
I actually reviewed one of these devices a few years back, and that experience left me wanting more. So I decided to upgrade to the GIECY G300, which is supposed to do what my previous amplifier did, only better, and maybe surprise me with a few new and interesting features along the way.
Join me as we find out what this device has to offer, and whether it's a real upgrade.
Product description
The Giecy G300 is a portable, multi-functional voice amplifier with a clear LED display, suitable for teachers, fitness instructors, tour guides, and anyone else who needs to project their voice clearly without straining it.
Design and Controls
All essential controls sit on top of the unit: a power/volume switch, a dedicated reverb switch, standard media buttons (Play/Pause, Next Track, Previous Track), and a Mode (M) button that cycles through the operating modes below.
Voice Amplification & Audio Overlay
At its core, the G300 operates in Speak mode (SP) through a connected wired headset. One of its more useful features is audio overlay: with the exception of Speak mode and Record mode, you can talk through the microphone while audio is actively playing from any of the other sources below.
Media and Connectivity Options
- Bluetooth Mode (Blue): pair the amplifier with any Bluetooth-enabled device to stream audio wirelessly, the same way a standard portable speaker would. Playback is controlled directly from the G300's top panel.
- USB & TF (Micro-SD) Modes: insert a USB flash drive or a memory card and the device immediately starts playing any stored audio files. If the inserted media has no audio, the amplifier switches to a different mode on its own.
- FM Radio Mode: a built-in radio with memory for up to 27 channels. Holding the Play/Pause button for 3 seconds scans and saves the available frequencies, which you then navigate with the Next/Previous buttons.
Recording & User Experience
Record mode (REC) lets you record your voice directly onto the inserted TF card or USB drive, using the Play/Pause button to start and stop. If both a TF card and a USB drive are connected at the same time, the recording is saved to the TF card.
To keep navigation simple, the G300 has a built-in voice prompt system: whenever you switch between modes, a female voice announces the current selection, giving you audio confirmation without needing to look at the display.

Inside the box
Pros
Respectable Battery Life Should comfortably last through an intensive working day of use.The manufacturer claims up to 15 hours of playtime (see Specifications).
Built-In Radio Works Well Strong signal reception, and once the stations are set, Radio mode plays clean sound with no disturbances.
Bluetooth Connectivity The first portable voice amplifier I've tried that offers Bluetooth. Pairing is easy, showing up as "G300" in your device's Bluetooth search, and even with its flaws, it makes the G300 more functional overall.
Effective Reverb Effect Works well, with a dedicated control switch on top of the device to adjust the effect level.
Recording Mode Lets you record yourself talking directly onto a TF memory card or USB flash drive, with quite good audio quality.
Impressive Volume Level The longer I used it, the clearer it became that the G300 is in a league of its own compared to other, lower-output portable voice amplifiers I've tested before.
Digital Display A red and orange display on top clearly shows the chosen mode, battery level, and more.
Decent Design & Build Quality Functional and easy to operate, with buttons and switches that feel and respond well. Its size lets you hold it in one hand, attach it with the belt clip, or carry it with the strap.Shaking it hard reveals slight internal movement of the speaker.
Cons
Weight It isn't that heavy, but it does feel heavier compared to previous portable voice amplifiers I've reviewed in the past.
Bass Is Essentially Non-Existent You can listen to music through this amplifier, but don't count on the bass. The main reason to use this device is amplifying your voice, not replacing a regular portable audio speaker for music.
Disturbance in Bluetooth Mode Setting the G300 to Bluetooth mode brings a disturbing signal that doesn't go away. It's less noticeable once audio is actually playing, but it's not something I'd expect from a Bluetooth connection.
Attachment Points Are Prone to Damage Build quality seems decent overall, but the strap holes and belt clip have the potential to break if too much pressure is put on them. Only time will tell.
Overall Verdict
Coming into this review, I expected a fairly standard portable voice amplifier, in the same range as others I've tested before. The G300 surprised me. The volume level alone puts it in a different category, and once I got past the initial setup, it became clear this device was built with more thought than most budget amplifiers in this space.
The feature set is what really sets it apart. Between the built-in radio, the Bluetooth streaming, the reverb effect, and the recording mode, there's a genuine reason to reach for each mode depending on the situation, not just a checklist of buzzwords. The digital display makes it easy to know exactly what mode you're in and how much battery is left, and the battery itself easily covers a full working day of use.
It isn't perfect. It's a bit heavier than similar amplifiers I've used, the bass is basically absent if you try to use it for music, and the Bluetooth mode carries a faint disturbance that never fully goes away. I also have a small concern about the strap holes and belt clip holding up to pressure over time, though the rest of the build feels solid enough. None of these are dealbreakers, but they're worth knowing going in.
A genuinely capable portable voice amplifier that goes well beyond the basics. If you need to project your voice clearly, whether for teaching, guiding, or instructing, the G300's volume, modes, and battery life make it easy to recommend. Just don't buy it expecting a music speaker.
