Maker hart Just Mixer S - 3 Channels 3.5mm Stereo Input/Output Mini Audio Mixer Battery/USB Powered Portable Pocket Audio Mixer

Exactly what I needed to be able to use my work laptop, while listening to music from another source. No fumbling with a screen and an interface to mute the music: just turn down the volume. Sound distorsion at high volume levels though.

Bought this as a away to combine my computer and iPod/phone audio into a single speaker. It is super simple to use, works very well and pretty sturdy too. Some of the earlier reviews mentioned the power switch would power the board from the battery mode when only powered via USB, but this is now fixed. I'm very impressed with sound quality, but please note that the quality of your USB power will have an effect on any noise and interference you hear.

Love the item. It's titchy, sounds good, runs off everyone's favourite supply and works perfectly to mix my Echo and TV into one amp. But that small size comes with the side effect that the leads plugged into it want to drag it around a bit. Sound quality is good (once you know how the controls work), but the low headroom before it distorts probably makes it useful as a "set and forget" mixer rather than a "live" mixer. However, the amount of gain available does give you some flexibility to plug in sources with low(er) output levels. Overall, a nicely presented little mixer, something I've been waiting for for a long time! But I can't give it 5 stars for value because.... (B) this is beginner circuitry that could be built in a matchbox for a couple of quid (with access to components at wholesale prices). That's completely ok but... (B) it comes in a posh box with a little printed cloth bag and two leads, one 3.5 to 3.5 and one USB. You're going to throw the box in the bin (it's not recyclable). You probably don't need a little printed cloth bag. You can't use it with one 3.5 to 3.5 lead - you'd need minimum 2 and that's assuming your devices aren't RCA - which is quite possible - in which case the lead they supply is redundant. Who doesn't have a glut of micro USB leads? The good bit of the package is the card reassuring you that you'll be looked after - if it's true it's a great thing to hear, well done. Don't get me wrong, it's a great thing, but if it was 25 quid and sold "naked" it would be super appealing to geeks like me who can't be arsed to make their own, and I suspect still allow a decent margin. I wouldn't have one, I'd have two, just in case. As it is, I'm looking at a small heap of landfill wondering if this could be sold as the "upsell" sorry I mean "deluxe" package (but with TWO leads and RCA converters, and a metal base to weigh it down) if you do really want that premium feel....

I almost returned this product after using it with batteries due to an unbearable amount of white noise when in use. I saw a review for a different product that had the same problem which was fixed by using the power cable instead of batteries. This seems to have worked for me as well.

- Buzz signal noise. - Certain distortion regardless of gain/volume combinations. Unusable basically, returned.

I am completely blown away with the quality of this small mixer. I needed one as when I combined the audio from my phone (for music) with the audio output from my laptop docking station (work meeting audio etc) the music audio was "dulled" due the differing impedances of the items. With this little mixer there is none of the dulling and it also amplifies quite a bit too (added bonus). Separate volume controls for each input too - although not really required for me as I can turn up the music audio independently (iPhone) and also docking station audio independently (laptop controls). It was more costly than I wanted to pay, but I had read other good reviews and knew that if it's no good then I can return it. Not a chance it will go back unless it dies (which I doubt as it seems very well built - as though care has been taken with it's design)

This does exactly what I needed it to. Allows me to combine numerous audio sources and monitor them for zoom calls. As mentioned in the other reviews there is a bit of noise in the background, but controlling the various levels correctly knocks it back to a barely noticeable level. All in all happy, especially for the price.

I'm following every word on the manual, using the original usb cable, even bought ferrite beads, new audio cables, and worked on my desk's cable management to reduce interference, but nothing really eliminate the noise I've been hearing. It helps a bit if I use a AMP between the mixer output and my headphones, but that wasn't my initial purpose, and doesn't completely eliminate it. Aside from the poor noise insulation, everything else works as you'd expect. On my current set up it sadly became unusable, might not be the case for everyone, but I'm honestly disappointed.

The sound management quality was excellent... simple to operate... and, all controls (gain for each of the three channels and the master volume control) function with great smoothness and linearity! Two quality connecting cables are included— one for power access, the other for audio interconnection. The unit operates on a pair of AAA batteries (included), or via the use of the enclosed USB power cable. Additionally there are two front panel audio output jacks one for headphones, the other for direct connection to an external amplifying audio device. A 3-position slide switch provides a power-off option, an internal battery power source option, or a USB external power feed. A very bright colorful (2 colors) led illuminates to show which power source is in operation. Also, the packaging is first class and the large printed instruction sheet is among the best I’ve ever seen! I use it for my amateur radio station multi-devices audio integration control. It works very well and it is totally free of any 60 Hz hum. I would recognize that the most common use for this mixer is to provide merged audio mixing for up to three devices (I.e. tablets, I-pods, radios, etc.).

L'ho acquistato per fare RSI (remote simultaneous interpreting) perché consigliato da una brava collega e l'ho usato per un po'. Non so perché, ma a un certo punto sentivo un brutto rumore di fondo. Non avendo tempo di approfondire, sono passata a un mixer più professionale. Lo tengo ancora perché è piccolo e molto leggero, sperando di risolvere magari un giorno il problema. Ma forse è proprio la leggerezza e scarsa solidità a renderlo meno affidabile.

Ich nutze es mit mehreren Bluetooth Transmittern um mehrere Geräte mit Ausgabe an einen Bluetooth Kopfhörer zu senden. Das klappt soweit gut, allerdings gibt es manchmal leichte Störgeräusche, liegt aber an den Adaptern. Bin zufrieden.

Ik heb hem in een hoekje van mijn (oude maar uitstekende) Yamaha klavinova staan waardoor ik een aantal extra bronnen door de speakers van de klavinova kan laten klinken: - muziek uit mijn ipad om mee mee te spelen - mijn elektrische Roland sax - geluid van de klavinova zelf via midi en een Hammond emulator in een iPhone of iPad Signaal/ruis verhouding lijkt goed in orde

Works well enough on battery power but as soon as you plug it into a USB lead to power it, there is a very noticeable 60 buzz. Very disappointing considering it wasn't priced like a toy that it turned out to be.
