Built Like a Tank, Designed to Perform

Right out of the box, you feel it. This isn't lightweight plastic. The metal body construction is built for durability—a professional finish that promises longevity. Ready for daily streaming, intense podcasting, or critical vocal recordings. Whether on your desk or boom arm, it's a clear statement: you're serious about your sound.

Professional Design, Pristine Sound Quality

This Aces microphone features a clean, minimalist all-metal design. With all the controls sitting discreetly on the lower body, this microphone is professional and camera-friendly without a visual distraction for streams and broadcasts.

The shock mount features an intelligent elastic suspension system instead of nuts and screws. This effectively isolates desk vibrations and reduces low-frequency rumble, letting your voice come through clearly and naturally—no muddy or boomy noise.

The Heart of Pro Audio: Why Directionality & High SPL Matter

Features a tight cardioid polar pattern, the K688 intelligently captures the sound directly in front of it (that’s you!) while actively rejecting noises from the sides and rear. That computer fan humming? The hard drive whirring? This mic virtually ignores them. Now, let’s talk power. With a max SPL of 130dB, this mic handles everything from whispers to powerful vocal bursts without distorting. Your audio stays clean, dynamic, and true to your performance—no clipped peaks, just pristine, natural sound.

Two Modes, One Studio Quality

For the Purist (XLR Mode): Connect via XLR to your mixer or audio interface. It minimizes circuit noise with a noise-cancelling S/N Ratio >80dB, unlocking a wider, more natural audio space. It's a pro path for the richest detail and voice resonance.

For the Plug-&-Play Creator (USB Mode): Use the included 8.2ft USB cable for instant connection. No drivers, no fuss. It’s perfect for quick sessions on your Windows or Mac laptop. This is true studio-quality sound without the complexity.

Total Control at Your Fingertips (USB Mode Features)

Real-Time Headphone Monitoring

Want to hear exactly what your audience hears—as you record? With real-time headphone monitoring built right into the microphone, you can. Plug your headphones into the 3.5mm jack to hear exactly what you’re recording.

Direct Mic & Headphone Volume Controls

Adjust your input volume right on the mic. No digging through software menus mid-stream.

The dedicated volume wheel lets you balance the audio mix perfectly, so you can catch issues before they become problems.

The FIFINE K688 is more than a microphone; it’s your all-in-one audio solution for podcasting, streaming, voiceovers, music, and content creation.

FAQs About FIFINE K688 Mic

1. PS5 and Xbox compatible?

PS5✔️ for sure. Hook it up to the PS5 console USB port with the included USB cable, and set the mic as the default input and output if your 3.5mm wired headset is plugged into the mic.

Xbox❌ is a no-no. Third-party USB audio devices aren't allowed to work with Xbox; this K688 is no exception.

2. FIFINE K688, AmpliGame AM8, and Tank3 are USB/XLR dynamic mics, but what are the differences between them?

The main difference is about the tone; the K688 is more on the high-and-mid, while Tank3 is the most neutral-sounding one among the three, while the AM8 sounds most like traditional dynamic microphones with a lot more bass.

Or let's put them into real life, if you're concerned about the background but don't want your voice to sound quite bassy, the K688 could be a better fit out of the three. The AM8 has the advantage of noise-rejection over the rest two if the environment is super noisy, like in your gaming room. At last, the Tank3 fits a wider range of users; you don't have to worry about your voice getting muddier or more harsh.

Besides the coloration, the appearance and the build quality might also be the deciding factors in this price range. If you want to stand out and add some flavor in the frame, the AM8 with a square shape and RGB lighting is the clear winner. If it's about the opposite style, then the Tank3 is the best fit for its super solid metal body, which is even 1/3 heavier than the K688, but in a more compact body.

3. Are the function keys of this studio microphone available for XLR connection?

No. All the function keys, like the gain knob and mute button, are only available for USB connection. If you want to use the function keys via XLR connection, please connect the mic to a computer via USB connection at the same time.

4. How to get clear and clean sound from the podcast dynamic mic?

We suggest facing the top of the cardioid dynamic microphone and speaking into it in a 2-6 inch range. Please remember to adjust the microphone gain knob to the proper level before speaking.

5. What devices does the fifine k688 usb/xlr work with?

This mic works with a computer, PS4/PS5 via USB connection. And it also works with an audio interface and mixer via XLR connection (XLR cable is not included). But it's not recommended to use this mic with instruments.

6. Can I use this recording microphone on Android or iPhone?

It works when using with a proper USB adapter. But we recommend using it only with Windows and Mac computers, since the quality of the adapters may vary and the low-battery status of your phone may affect the performance of the mic.

🍎iPhone/iPad with a type-C port needs a type-C male to type-A female adapter.
🍎iPhone/iPad with a lightning port needs a lightning male to type-A female adapter.
⚠️If it's the lightning version, because of the protocol, it's highly recommend the adapter from Apple store. https://www.apple.com/shop/product/MD821AM/A/lightning-to-usb-camera-adapter
🤖Android with a micro-USB port needs a micro-USB male to type-A female adapter.
🤖Android with a type-C port needs a type-C male to type-A female adapter.

7. Can it be attached to a boom arm? Or how can I set it up if I got the K688CT/K688T (mic with boom arm version)?

The thread size is standard 5/8". To attach the mic onto a scissor arm stand, you need to screw the 5/8" to 3/8" adapter that comes with the arm to the shock mount in the first place.

And a tutorial on using the FIFINE BM63 boom arm with the K688 is below. The steps are the same when you use the K688 with another arm stand.

8. How can I tell if the CS1 boom arm that comes with the K688CT (mic with boom arm version) fits my desk?

FIFINE K688 dynamic microphone could be much better if…
Too muddy sound in USB mode and a little bit better in XLR. It’s a pity because the construction and design are great.

Wholly Molly
When I purchased this mic I was skeptical to say the least when I saw the price. My skepticism has never been so wrong. This mic is absolutely worth every dollar and more. My audience noticed a huge difference in quality when i changed over. I can't wait to see what Fifine comes out with next!

Great microphone with great support
As soon as I saw this microphone, I knew it was time for an upgrade... I obviously don't want to spend $500 on a mic like the Shure SM7B but this microphone has a sleek design with a really similar sound at a fifth of the price so I bought it. It took about a month to come since it came overseas from China but it wasn't the biggest deal, upon receiving the microphone it sounded great but I only had 2 concerns, first of all, one of the rubber bands holding the shock mount to the microphone fell off somehow so I had to spend an hour trying to re-attach it as it is a very tight fit but other than that the microphone sounded great and I was super happy with it until day 2 when the USB-C cable included with it just stopped working, luckily I tried a different cable and it worked again so I just contacted support and within a day, they responded to me and sent out 2 replacement cables. All in all, I am very happy with this microphone and would highly recommend it if you're on a budget as the only issues I encountered was probably just me being unlucky and will all be solved.
