[2 x 1 x 0.6"] Ill first start by saying that this amplifier has a nice sturdy metal build. While there are many uses for this device I am using it along side my mixer board. Sometimes I need an extra headphone out and this works well. I just took a long 1/4 cable and plugged it into one of my mono outs and then into this Polsen amplifier. Since it is a mono source you can simply move the internal switch from stereo to mono. That way you can have sound in both of your headphones. So far it works great for the way that I'm using it and its plenty loud. Just be careful when sliding the case back on as you can accidentally pinch some exposed wires that hang near the battery tray. The only thing I have not tested is how long the batteries will last as you will need batteries to operate it. This would be a great option for live performers or someone like me who just needed an extra headphone out.


[I received this product in exchange for my honest review.]

[2 x 1 x 0.6"] This is a great piece of gear. Great quality.

[0.04 lb] As lead singer for Hypnotik, an in ear system was so needed for stage volume control and we were on a tight budget. The Polsen did wonders for the band

[0.04 lb] Works just like advertised.

[0.04 lb] Does what it says, even if it is a bit pricey.

[0.04 lb] This one works very simply and the sound is good and loud enough. Use it every Sunday for church and it has been serving very well.

[2 x 1 x 0.6"] I Purchased (4) of these for a Streaming studio project and am VERY happy with them. They are well designed and work really well. As they are active, they require batteries which we the manufacturer was thoughtful enough to include (2) AAA batteries, so they can be used right out of the box. I would definitely recommend this product.

[0.04 lb] There are a ton of expensive wireless in-ear systems out there for performers to hear themself without having to lug huge monitors around that take up stage space. But as a bass player I really didn't need a wireless system as I was tethered by my guitar chord already. I first looked at passive belt clip style wired types but settled for a battery powered active wired unit. It worked really well straight out of the box. I could select mono or stereo. It was compact and easy to use and I could boost the volume if the band got louder. But we generally found as all the members switched to in-ear units, our stage volume was noticeably quieter.
I would strongly recommend this neat and compact unit.

[0.04 lb] Rough, small, powerfull, good price

[2 x 1 x 0.6"] Works great for my amplifier on the cello. Would recommend getting good quality headphones. Gets the job done for a really loud stage and when you really need to hear yourself.
