Fairly quiet too - Recommended :) - UPDATE2: Well, this mixer is working perfectly well now. And, I can't replicate any of the problems I was having with this mixer when I first got it. I was getting tons of noise when running off batteries, didn't matter if they were rechargeable or alkalines, and the USB power pack I was running it off of kept shutting down. The seller was responsive as well and assured me that they stand behind their products. I've hooked up this mixer nearly a dozen times now... used an assortment of different cables, mics, aux inputs. I've used it on an iPhone SE and an iPad Pro. Everything has worked perfectly. I CAN get a little bit of noise if I have the mixer sitting right next to the iPhone when they're hooked up together... but nothing like I was getting before. No clue why it's working now, or why it wasn't at first. The best speculation I've got is that when I first unboxed it, and then plugged in the first 3.5mm mini cables into it's 1 & 2 channels, there was some rough resistance. They didn't go in smooth like you'd expect. They do now, but I'm wondering if there was maybe a bit of metal that didn't get finished out inside one of the ports that got knocked free and was causing some kind of short circuit situation? No idea, but now that it's been working perfectly without any hint of the initial problems I experienced, and that now that I know the seller stands behind the product... I don't have any reservation giving this a solid 5-stars. It works well, it's affordable, it's lightweight, easy to use, and functions well off AAA batteries. I'm even having good luck with rechargeable AAAs. Recommended! :) ___ UPDATE: The seller got back to me quickly and offered to give me a small discount after returning/refunding to desertcart then rebuying the mixer. However, after lots of testing yesterday before concluding something was definitely wrong with this mixer... all of the problems went away after reconnecting everything later at a coffee shop. Then later in the evening at home, it was still performing flawlessly. And later in the night, I tried again... did everything exactly the same as before... but nothing would repeat the same failures I'd experienced. Even running it off Ni-MH rechargeable AAAs was perfectly quiet. Earlier, the Just Mixer was shutting off my USB battery pack as well. I'd assumed it was an auto--shutoff in the pack... and it was shutting of due to low power drain, but even that has stopped. The mixer works fine and I'm unable to reproduce the problems I was having before. I'm hesitant to give this more stars yet, in case the mystery problems promptly reappear. But I'll bump it up to 2-star until I'm certain the problems were just a rare fluke. If it's still working fine in a week or so, I'll update the review accordingly. ___ Hello, I bought this mixer a couple weeks ago. The blue one. I'm getting a lot of noise when run off batteries. At first, I thought it was because I was using rechargeable 1.2v Ni-Mh batteries... so as you recommend on your product page, I tried brand new Energizer 1.5v AAA alkaline batteries. Still there's noise. When I'm using the mixer off USB or a USB battery pack, there's no noise at all. ONLY when using AAA batteries. Is there something wrong with this mixer? Would you like to send me a replacement? Or, should I get a refund from desertcart for this? I bought this MOSTLY because it's says it runs off of AAA batteries. If it can't function without excessive noise while running off AAA batteries alkaline OR rechargeable.. it's useless to me. Review: great little mixer - ---Please read warning below--- If mixing through 3.5mm TRS AUX is something you want to do on the go or while using temporary setups, this mixer is pertty sweet. works well on battery as well as through usb power ( i only use portable power banks when using usb power with this to cut down on noise ). the faders work very well but i did have to take my unit apart because one of the fader nobs was touching causing it to bind slightly. after adjusting how tight all the screws were ( some had to be looser than they came and some needed tightened ) i was able to get them all moving smoothly and evenly. that said there is a little bit of noise in the amp, about as much as you might expect from cheaper gear but its not terrible. the overload limit light does not always come on when it is over loading or comes on when it is not. not the most accurate clip indicator but again it is on the cheaper side. WARNING- if you are using IEM's or headphones be careful not to let the batteries die while your listening through this mixer! the sound is odd and disorienting right before it pops VERY VERY loudly. again only when the AAA batteries die completely while you are plugged into speakers or headphones but it has happened to me a few times and it is not fun at all. ## Features - Versatile and Compact - The perfect way to mix multiple sound sources whenever and wherever you are (ideal for mixing audio/music from computers, smartphones, tablets, gaming consoles, desertcart Echo/Dot, mics and instruments) - Stereo 3 in / 1 out Configuration - 3 stereo channels (3.5mm / 1/8") allows up to 5 mono input connections - Signal Level - Gain knob allows input of multiple devices from mic to line level (high-sensitivity microphone recommended if using mics) - Overload Indicators - LEDs will light up when signal level overloads mixer capacity; monitor for optimal audio performance - Mix Monitoring - Connect stereo headphones for convenient stereo monitoring and use as a sub-mixer. PS : This product does not have microphone power supply. Cannot be used with microphones (for example: USB microphones, condenser microphones). When using the product, it is recommended to use the original accessory cable to reduce external noise interference. It is also recommended to increase the volume of the audio source to reduce the occurrence of white noise. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01LPT8JY8 | | Audio Input | Auxiliary | | Best Sellers Rank | #41,546 in Musical Instruments ( See Top 100 in Musical Instruments ) #217 in DJ Mixers | | Brand | Maker hart | | Brand Name | Maker hart | | Connectivity Technology | USB | | Customer Reviews | 3.9 out of 5 stars 678 Reviews | | Item Dimensions D x W x H | 0.94"D x 4.13"W x 0.94"H | | Item Weight | 114 g | | Manufacturer | Maker hart | | Manufacturer Part Number | 85U06B01R0-Blue | | Model Number | 85U06B01R0 | | Number of Channels | 3 | | Number of Items | 1 | | Output Connector Type | Auxiliary | | Power Source | Usb Cable,Corded Electric,Battery Powered | | Product Dimensions | 0.94"D x 4.13"W x 0.94"H | | Software Update Supported to Date | unknown | | Unit Count | 1 Count | | Voltage | 5 volts | ## Product Details - **Brand:** Maker hart - **Connectivity Technology:** USB - **Item Weight:** 114 g - **Number of Channels:** 3 - **Product Dimensions:** 0.94"D x 4.13"W x 0.94"H ## Images ![JUST MIXER Audio/DJ Mixer - Battery/USB Powered Portable Pocket Audio Mixer w/ 3 Stereo Channels (3.5mm) Plus On/Off Switch (Blue) - Image 1](https://m.media-amazon.com/images/I/81GNYl3rrQL.jpg) ![JUST MIXER Audio/DJ Mixer - Battery/USB Powered Portable Pocket Audio Mixer w/ 3 Stereo Channels (3.5mm) Plus On/Off Switch (Blue) - Image 2](https://m.media-amazon.com/images/I/71BUIgZbvJL.jpg) ![JUST MIXER Audio/DJ Mixer - Battery/USB Powered Portable Pocket Audio Mixer w/ 3 Stereo Channels (3.5mm) Plus On/Off Switch (Blue) - Image 3](https://m.media-amazon.com/images/I/91F1eWlKpkL.jpg) ![JUST MIXER Audio/DJ Mixer - Battery/USB Powered Portable Pocket Audio Mixer w/ 3 Stereo Channels (3.5mm) Plus On/Off Switch (Blue) - Image 4](https://m.media-amazon.com/images/I/81MlHngreNL.jpg) ![JUST MIXER Audio/DJ Mixer - Battery/USB Powered Portable Pocket Audio Mixer w/ 3 Stereo Channels (3.5mm) Plus On/Off Switch (Blue) - Image 5](https://m.media-amazon.com/images/I/91WcnnMwOdL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ UPDATE: A fun mixer that works well, even off AAA batteries.

I've had mine for about three years, traveling with it and commuting. It works great on battery or USB power. The Aux knob has gotten a little scratchy but it's just from dust. I can wipe it back and forth a few times and it settles down. There is no noise from the mixer on either battery or USB if the USB is a separate power supply like a good phone charger. Sometimes it can get some noise if i'm powering it by one of the devices in the mix. If the battery is going out it will squeal. Having used this nearly every day for three years, I can say it is very quiet if properly powered. It's pretty durable for being plastic and feels solid yet light in weight. The blue version is handsome and the orange version is adorable. Makes me smile when I see it. The sound quality is unbelievable for being such a tiny device that can run on batteries. I have used it to mix audio from computers, cellphones, IP phones with proper adapter (that is some noisy signals!), portable music devices, gaming devices, and music equipment. Not all at once of course. It only has three stereo inputs! And these are real, analog channels so there's no processing or lag. Two of the channels have controls for gain and balance. Mostly I keep them in neutral positions but they do work when I need a little boost or to nudge a signal to one side. I'm not sure how loud this can boost a signal. I have had no trouble powering big headphones or iems. Even tried with a planar magnetic Hifiman pair and it got loud enough. I have used it with a small portable speaker but nothing really big or certainly nothing without it's own power supply. I think any type of headphones would be just fine at responsible listening levels. I can't recommend the Maker Hart Just Mixer enough. It's been my little music buddy for a while now! ## Frequently Bought Together - JUST MIXER Audio/DJ Mixer - Battery/USB Powered Portable Pocket Audio Mixer w/ 3 Stereo Channels (3.5mm) Plus On/Off Switch (Blue) - Amazon Basics 2-Pack 3.5mm Aux Audio Cable for Stereo Speaker or Subwoofer with Gold-Plated Plugs, 4 Foot, Black - BESIGN Ground Loop Noise Isolator for Car Audio/Home Stereo System with 3.5mm Audio Cable --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/34788627-just-mixer-audio-dj-mixer-battery-usb-powered-portable-pocket](https://www.desertcart.sg/products/34788627-just-mixer-audio-dj-mixer-battery-usb-powered-portable-pocket) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-10-15*
