AI Verdict
This is a solid starter kit for aspiring streamers and podcasters who want the flexibility of USB now and an upgrade path to XLR later without buying new gear.
For its entry-level price, the K688 offers a strong fit by providing both USB and XLR connectivity, which is rare. This gives new creators a simple plug-and-play start with an easy upgrade path to a more professional XLR setup without needing to buy a whole new microphone. The included heavy-duty boom arm and shock mount add significant value, making it a complete starter package.
If you find the XLR volume too low, look for an audio interface with high-gain preamps (around 60dB or more) or budget for an inline mic booster.

Pros
- Dual USB and XLR outputs provide plug-and-play ease and a future upgrade path.
- The all-metal body feels sturdy and more premium than its price suggests.
- Cardioid pattern is effective at rejecting background noise like keyboards and PC fans.
- On-mic controls for gain and headphone volume are available in USB mode.
- The included boom arm is heavy-duty and can support heavier microphones.
- The kit includes a shock mount and pop filter, so it's ready to use out of the box.
Cons
- On-mic controls like the mute button and gain knob are disabled when using the XLR connection.
- The included C-clamp for the boom arm only fits desks up to 2 inches thick.
- The XLR output level can be very low, often requiring a powerful preamp or a separate mic booster.
- The touch-sensitive mute button is easy to trigger accidentally when adjusting the mic's position.
- The microphone body is lightweight and can pick up a lot of handling noise and desk vibrations.
Dimension Scores
Provides a clear, neutral vocal tone that's great for spoken word, though it can sound thin if you're too far away.
The mic has a decent bass response up close due to the proximity effect, but the output volume over XLR is notably low and often requires significant gain.
Having both USB-C and XLR outputs is a best-in-class feature for this price point, offering incredible flexibility.
The microphone itself has a solid metal body, and the included boom arm is surprisingly heavy-duty, though the plastic shock mount attachment point is a concern.
Best For
- Beginner streamers who need an all-in-one package with a mic, arm, and shock mount.
- Podcasters on a budget who want to start with USB and upgrade to an XLR mixer later.
- Gamers who need clear voice chat and good rejection of keyboard and mouse clicks.
- Home office workers looking for a significant audio upgrade for video calls.
Not Recommended For
- Professional voice actors who need the lowest possible noise floor and sensitivity.
- Musicians recording loud instruments, as the mic's primary focus is vocal clarity.
- Users with desks thicker than 2 inches, as the included boom arm clamp won't fit.
Watch Out For
- XLR volume is surprisingly low. Many users report needing to crank the gain on their audio interface to nearly 100% or buy an inline preamp like a Cloudlifter to get a usable signal.
- The boom arm clamp is a weak point. It has a small contact point and can slide or fall off desks with beveled edges or slick surfaces.
- Windows 11 updates can reset audio drivers and cause the mic volume to become extremely low in USB mode, requiring manual adjustments in the sound control panel.
- The touch-to-mute button is very sensitive. You can accidentally mute yourself just by brushing against the mic while adjusting it.

What Buyers Say
The most surprising thing about this mic is how much you get for the money. The dual USB/XLR connection is the killer feature, giving you a clear path from beginner to a more advanced setup. The sound quality over USB is immediately impressive for the price, with good clarity and background noise rejection. However, when you switch to XLR, be prepared for a very quiet signal that will need a lot of gain from your audio interface. The included boom arm is a beast—heavy and sturdy—but the desk clamp it uses is its Achilles' heel, struggling with any desk that isn't perfectly flat and under two inches thick. The on-mic controls are useful, but remember they only work in USB mode.
“i was ready to be disappointed by another cheap amazon mic but this thing sounds way better than it has any right to and the fact i can upgrade to my buddy's old mixer later without buying a new mic is just insane for this price.”
Common Praise
- The flexibility of having both USB and XLR outputs in one microphone is a huge plus for future-proofing.
- It sounds surprisingly good right out of the box in USB mode, with minimal setup required.
- The all-metal construction of the microphone feels solid and durable.
- It's very effective at rejecting off-axis noise like keyboard clicks and room echo.
- The included boom arm is much more robust and heavy than expected for a bundled accessory.
- The price-to-performance ratio is excellent, competing with mics that cost significantly more.
Common Complaints
- The XLR output signal is extremely low and requires an audio interface with a high-gain preamp or a separate booster.
- The boom arm's C-clamp is small and can easily slip off desks with rounded or beveled edges.
- The touch-sensitive mute button is too easy to hit by accident when adjusting the mic.
- The microphone is sensitive to bumps and vibrations transferred through the stand or desk.
- All on-mic controls are completely non-functional when using the XLR connection.
- The plastic part where the shock mount connects to the boom arm feels like a potential breaking point.
Ownership Tips
- After a few weeks, you'll learn to be very careful when adjusting the mic to avoid accidentally tapping the mute sensor.
- You might find yourself constantly checking if the boom arm clamp has started to slide, especially if you move the arm around a lot.
- If you use XLR, you will eventually get tired of cranking your interface gain to 90% and will start shopping for a Cloudlifter or FetHead.
- The convenience of plugging headphones directly into the mic for zero-latency monitoring in USB mode is something you'll really miss if you switch to a USB-only mic without it.
Frequently Asked Questions
Do I need to buy an XLR cable separately?
Yes, the kit comes with a USB-C to USB-A cable, but an XLR cable is not included.
Do the volume and mute controls on the mic work with an XLR connection?
No, all the on-mic controls are disabled when using XLR. You must control gain, volume, and muting through your audio interface or mixer.
Is the microphone volume low?
Many users report low volume, especially over XLR. For USB, ensure the gain knob on the mic is turned up and check your computer's sound settings. For XLR, you'll likely need an audio interface with a strong preamp.
How far away from the mic should I be?
For the best sound and to minimize background noise, you should be about 2 to 6 inches away from the front of the microphone.
Does this mic need phantom power?
No, as a dynamic microphone, it does not require 48V phantom power. Turning on phantom power when connected via XLR may cause the mic to cut out.
How thick of a desk can the included boom arm clamp to?
The C-clamp on the included boom arm fits desks that are under 2 inches thick.
Can I replace the included foam windscreen?
Yes, the included windscreen is removable. Some users have found that replacing it with a windscreen designed for the Shure SM7B can help reduce plosives (popping sounds).
Buying Guide
This is a dynamic microphone, which means you need to speak directly into the front of it from a few inches away. It's designed to capture your voice and ignore sounds from the sides and back, which is great for untreated rooms with background noise. The biggest selling point is the USB/XLR combo. You can start by plugging the USB straight into your PC for dead-simple setup. Later, if you want more control, you can buy an audio interface and use the same mic with an XLR cable for better processing and multi-mic setups.
Connectivity: USB/XLR
Think of it like a car that can run on gas or electric. USB is your simple, all-in-one 'electric' mode—just plug it in and go. XLR is the 'gas' mode; it requires a separate 'engine' (an audio interface) but gives you more power and control over your sound.
Pattern: Cardioid
This mic listens in a heart-shape pattern. It's most sensitive to what's directly in front of it (your mouth) and rejects sounds from the sides and rear (your keyboard, PC fans, or annoying roommate). You have to talk into the top/end of it, not the side.
On-Mic Controls (USB Mode)
When plugged in via USB, you have a volume knob for your headphones and a gain knob for the mic's sensitivity right on the body. This lets you make quick adjustments without fumbling with software settings during a stream or call.
Alternatives
If you don't need the future XLR upgrade path, look for a USB-only dynamic microphone which may offer simpler software controls. If you already own an audio interface, search for an XLR-only dynamic microphone, which might offer slightly better sound quality at a similar price by focusing all its components on the XLR signal.
