Features 7

  • [Clean Sound Quality] Featured with durability and adaptability, the metal-build podcast microphone, with SPL of 130dB, will not distort the audio from vocal, video or music recording to keep its originality. Quite directional cardioid pattern deals with background noise, like hard drives or computer fans. The microphone for PC delivers detail voice without much additional noise processing. (Arm stand, mic stand and XLR cable are NOT included.)
  • [Upgrade XLR Output] XLR microphone reduces circuit noise interference and enhances the sense of audio space. Worked with S/N Ratio higher than 80dB, the dynamic microphone upgrades dynamics and details to makes your vocal easier to resonate. Use the streaming mic with sound card or mixer equipment accessories in your studio to present more natural and high-end audio in recording, vocals.
  • [Convenient USB Output] Provided with both XLR to USB connections, the dynamic USB microphone is a significant benefit for you to record in various ways working with Windows or Mac OS. You can save time to finish your work quickly on desktop or laptop by plugging the 8.2ft USB cable directly without any further software or settings. The gaming microphone readily satisfies your daily work in studio, and also portable when out for work.
  • [Mute and Gain Control] Tap-to-mute on the front panel is handy to control instead of pushing a button, which is quiet to avoid unnecessary noise into your vocal or singing. No need to fiddle with software settings on your Macbook, you can adjust the input volume level by gain knob on the recording mic for podcast, to output more vivid broadcast audio. (Only available for USB connection)

Good quality, Great customer service
Set name: Black-K688 Mic
I’ve been using this brand of microphones and audio equipment for many years. I’ve had this microphone for almost 2 years now, it still works perfectly fine. This is by far the best budget microphone for the price. It comes with a usb-c cord with a usb-a adapter for your pc. It also has a usb-c port, and an xlr port. It was super easy to plug and play, with no additional installations like drivers or anything. It sounds clear and works great. It has a little mini tripod, but if you have a boom arm, it’s easily adjustable to the direction you want it to be. It has volume sliders in the back for gain levels. The only issue I’ve ever had was the mute button, it came off of the spring. I emailed FIFINE within 1 year of purchasing this specific microphone for that issue. The spring still muted and unmuted the microphone, so it was a small issue, but it was definitely an inconvenience. I use a mixer that I bought from them, so I don’t have to mess with the mute button spring anyway. Instead of them just sending me the 3d printed piece that probably would have cost them $0.10, they sent me a whole new microphone for FREE. I didn’t even have to send back this one to the company. Their customer service was great! I got an email response within a WHOPPING 30 minutes. That’s the fastest customer service I’ve ever seen. They sent the replacement mic within a few days, and I received it within 7 days of the first email that I sent. Sound quality: 8/10 Accessories: 8/10 (could include an xlr cable) Ease of use: 10/10 Build quality: 9/10 Customer service: 10/10 Overall rating: 9/10 ... show more

AMAZING mic for the price
Set name: Black-K688 Mic
Honestly didn’t expect much for the price, but this mic is awesome. My room has zero sound treatment and my PC fans are pretty loud, but because it’s dynamic it barely picks up any of that background noise. My voice sounds super clear and full right out of the box without needing to mess with EQ settings. The tap-to-mute button on top is super convenient for Discord calls, and having both USB and XLR means I can plug it straight into my PC now and upgrade to an audio interface later. Easily worth every penny. ... show more

The Best Mic & Boom Arm Combo Ever – Unbelievable Audio Quality!
Set name: White-K688W Mic
I bought and paid for both the K688 microphone and the low-profile boom arm, and I honestly couldn't be happier with this purchase. First, I have to talk about the K688 microphone itself. The audio quality on this thing is unbelievable. It is such a massive step up from any normal, regular mic I’ve ever used in the past, and it literally sounds better than any other mic I’ve ever owned. The voice clarity is top-tier, but the background noise isolation is what completely blew me away. I put it through a full real-world test right at my desk: I have an air purifier running right next to me, my ceiling fan on, a second fan running in the room, and the air conditioning blowing, and this mic cuts all of it out completely. You don't hear any of that noise in the background, and you don't hear my keyboard typing at all either. All you get is crisp, crystal-clear audio. For recording and streaming, it is genuinely perfect. Below the mic, the low-profile boom arm is just as impressive. I love the sleek white look of it—it gives my entire desk setup such a clean, modern aesthetic, and the mic looks awesome mounted on top of it. Beyond the visuals, the build quality is crazy solid. It’s made out of super strong materials, and the desk clamp is extremely thick and heavy-duty. Once you clamp this thing down, the boom arm literally does not move or go anywhere. It holds its exact position, doesn't sag, and does every single thing you could possibly want a high-end boom arm to do. Honestly, the setup process was another huge plus. It literally took me maybe two minutes to completely set up the boom arm, and then it literally took me 30 seconds to attach the mic to it. It's an amazing thing. It takes literally no time at all to get this entire setup ready to go. For cable management, all I did was run the wire right through the boom arm to completely hide the cables, and it makes everything look incredibly clean and professional. Overall, this entire setup is insanely well-built, reliable, and honestly perfect for anyone looking to upgrade their audio. Fifine is an amazing company, and this is easily one of the best products and brand experiences I've ever had! One last thing I want to mention is compatibility. It works with Windows and Mac computers, PS5, Android and iOS devices via USB, and standard XLR gear if you ever want to hook it up to a mixer (just keep in mind it isn't compatible with Xbox due to console limitations). Personally, I’m running it on Windows 11 using a Type-C to Type-A connection—I'm not even using XLR—and it was literally 100% plug-and-play right out of the box. It works completely flawlessly! ... show more

Amazing for the price!!!
Set name: Black-K688 Mic
The K688 is a great all around mic. I spent weeks trying to find a good mic that wouldn't break the bank, but also sounded good, and didn't sound terrible when speaking. When I heard my friends voices through theirs, I knew it was right. I got my wife and I each one, mine being black and hers pink. I like that it's xlr/usb so I could try both. It's pretty durable for it being plastic. Sound quality is really good. You may want to keep the gain low knob low when adjusting it, the mic does pick up alot of sound if not adjusted. All in all this mic can compete with some of the higher end mics on the market, for WAY less. ... show more

Good mic
Set name: Black-K688 Mic
I got the FIFINE Dynamic Microphone and it works really well for the price. The sound quality is clear and crisp, and it picks up vocals nicely without too much background noise. It feels sturdy and easy to set up, making it great for streaming, podcasting, or casual recording. Not professional studio level, but excellent value for anyone starting out. ... show more

Super amazing microphone!
Set name: White-K688W Mic
The fifine K688 is an amazing microphone for its price! Since it utilizes both USB or XLR for connection, it’s a huge step up from the previous microphone i’ve used. The build quality is very nice and it feels super premium. The sound quality is also great straight out of the box, and with some adjustments it sounds absolutely amazing, and in my opinion comparable to SHURE microphones. The size is perfect, and its features are great. Best microphone i’ve had so far! ... show more

High Quality Microphone for a Small Price. Great for Content Creators.
Set name: White-K688W Mic
As a YouTube Content Creator, I was looking for the highest Quality Microphone I could get for a low price. There are some brands out there other YouTubers use that can cost a couple hundred dollars or more. Most of us who just start out on YouTube do not have that kind of money to spend. FiFine offers products to us at such an accessible price, it's hard not to take a look! The K688 is a Microphone that fits all my needs. I have used this Microphone in the USB configuration for several months and had absolutely no issues with it. The sound has been high quality giving me that studio sound that you would get from the higher price microphones. Recently, I added an audio mixer into my setup, the FiFine SC3 so that I can connect to XLR and use that quality. This microphone sounds great in XLR! But, it sounded great in USB mode too. I feel like regardless of how you wish to use this microphone, it will do an amazing job. When I first received the K688 it was extremely easy to use. You simply plug in the USB/XLR and plug it into your device you are connecting to. I purchased this microphone in the Color white to fit my setup. While in USB configuration you can adjust the microphone gain and the headphone volume with the Microphones knobs. You can also mute/unmute the microphone by simply pressing the touchscreen style mute button on the microphone. These features are not accessible in XLR mode because the Audio Mixer (In my case FiFine SC3) would take over those functions. I would definitely recommend this Microphone to content creators who want to sound amazing without spending a ton of money. ... show more

An Awesome USB/XLR Microphone! Great for the Price and Super Easy To Use.
Set name: Black-K688 Mic
I’ve primarily used only Fifine Mic’s since I started content creation, I’ve had the K669B, and AM8 which has been my main microphone for the past year. The K688 is an excellent upgrade! The build quality is better, and the built in shock mount and better background noise reduction compared to the AM8 makes it worth it. The Metal build is super nice. I love the smaller design profile when compared to the AM8, and though not needed, the ditching of the RGB lights is something I do miss. I also love that it includes a USB A to C that can easily become USB C to C. The cable itself is pretty long, similar to the AM8, it makes it super easy to adjust it. Similar to the other Fifine mic’s I’ve had, this one works out of the box with no issues. The XLR compatibility is also super neat. I primarily just use the USB C cable, it makes it super easy to plug in and use. I highly recommend pairing the mic with a boom arm (Fifine’s BM63 is my personal recommendation), I hadn’t realized till now how much of a difference it makes and how much easier it is to stay close to the mic and maintain consistent volume and quality. On the audio quality, I have a pretty deep and monotone voice. I try to keep the mic as close as possible and project my voice to make it sound as clear and crisp as possible. I am still very impressed by the audio quality for this price, and I have no real complaints. I’ve had it for over 2 weeks as of this review, I would recommend it! ... show more
