For 50 bucks this thing is awesome!! For anyone just starting out streaming or on a budget, this thing will suit your needs just fifine (see what I did there? sorry, I couldn't resist ?)This has an XLR mic hookup (XLR cord not included but you can get one on here for under 10 bucks) and features auto-tune voice feature as well as a voice changer with 6 different settings. It has volume level sliders and while they aren't super sensitive they feel solid and are responsive enough.You can use a USB mic with it as well, but when you use an XLR mic the gain and mute are controlled straight on the mixer instead of the button and knobs on the USB option (I have this paired with a fifine K688 XLR/USB combo, both sound great but the XLR connection sounds a little bit better.) The K688 is truly plug and play, no software needed to run it but obviously you can record some audio then touch it up in audacity or whatever audio software you might use, but it honestly doesn't need it. If anything you might want to use it for background noise reducer as it is dynamic and picks up a lot.Anyway, back to the actual product I am supposed to be reviewing....(seriously, it's an awesome mic, check it out!)You have your microphone gain level slider, a slider for line-in, headphones (which give you real time headphone monitoring with zero delay!) and line-out slider with mute buttons underneath the mic, line in, and line out, and underneath the headphone slider is your mic monitoring off and on button. It comes with USB C to USB A with an attached USB C adapter cord for plugging into your computer or a charging brick for power and it is Mac compatible. It also has a headset port for those that want to use their gaming headset. This is the only feature that I haven't tested out on the mixer because I never use a headset when I am gaming. I do know just from some research that if you have a headset plugged in, regardless of what mic you are using, it will default out to the headset mic instead of a plugged in XLR/USB mic.It comes with (1) 3.5mm TRS to TRRS cord that you will use to connect to your smartphone and you will connect the TRS end into the line out port on the mixer and the TRRS end into a dongle (not included) into your phone and you are able to use your microphone for any audio that you might need while shooting videos on your phone. I have purchased a second TRS to TRRS 3.5mm cord as well as a splitter to connect both cords coming from the mixer into one connection into my phone. I haven't been able to test it out just yet, and even if its not capable of being connected to both ports at the same time, its not a dealbreaker at all, Ill simply just unplug whichever line port I don't need at the time.You can use the same cord for the line-in port to use probably my favorite feature of all on this thing, the CUSTOM sound effects buttons. It features 4 custom sound effects buttons that record roughly 18 sounds of anything, and I mean anything you want. You can record yourself, parts of a song, or like I have done, funny sound effects for when im streaming. You simply hold whichever button (A,B,C, or D) until it turns white and continue to hold and it will record whatever you are playing through the line or your voice through your microphone. Once you're done simply let go or if you record for the max amount of time on the button, it will simply change back from white to whatever color sequence is running on the mixer. Once you are ready to play it, simply hit the button and it will play and if you recorded the whole time slot but only want the first couple seconds to play, simply hit the button again and it will stop. The audio is slightly compressed on the recording and I mean slightly but again, for 50 bucks this is rock solid and again, probably my favorite feature. A way to have unlimited sound effects for when I am streaming on twitch and not using my phone, I open up a meme soundboard and the options are limitless and it really livens up the stream.Finally, the housing is made of plastic but its not a cheap flimsy plastic but a hard, solid plastic shell that will stand up to normal wear and tear at a desk and it has an RGB color flow with settings to change the color to a solid color with about 12 options with a light bar underneath the front lip that corresponds to the color setting you have selected.There are tons of unboxing and review videos on YouTube that pretty much showcase everything I have said here and some from some pretty sophisticated content creators that have mixers worth hundreds of dollars and everyone of them I watched before I purchased mine were blown away with everything you get in this mixer at an unbeatable price of $50 bucks. Is it perfect, no, but if you're just starting out or on a budget (I am both of those) you won't find a better mixer or even an XLR connection for the price.Even the customer service team at fifine are helpful and quick to respond to any questions or issues you might have.I love this mixer and use it every single day. I highly, highly recommend it as well as the other fifine products. You can get this mixer AND a solid XLR/USB mic for under $100! Check them out, you won't be disappointed!
