Logitech Speakers Loud Hum

Purchased this because I was getting loud lingering hum in my subwoofer and speakers every time my wife used the hairdryer or the fridge compressor kicked on. No longer! If you've got AC line noise, this will filter it out.

I had Logitech speakers for my computer in my house previously, but I moved into an apartment and thought they would be too loud for my 80 year old neighbors and gave them away. This year I moved in to a house again and kept wishing I had my old speakers back. I searched the Logitech site and found the Z323 system with an adjustable subwoofer and great sound! I'm back to rockin' out and enjoying my music again! :)

I got this item so my wife could stream music from her phone to our stereo system with the bigger speakers. All this without the need for wires. I installed the Logitech adapter per instructions using the supplied 3.5mm to RCA cable but noticed a hum. I used an RCA cable and connected it to the RCA jacks of the Logitech to the RCA jacks on my stereo and the hum went away. My wife easily paired her Samsung S5 to the Logitech and was able to immediately stream her country music. She was able to crank up the volume...which was pretty loud. The sound was quite good. She was able to walk around the house, roughly 20 to 30 feet, with no break in streaming. We were impressed with the performance of the Logitech. I would definitely get another one.

I was looking to replace my external speakers because of a hum. The usb model was the way to with a respectable brand name.

This 2.1 system by far is the best set-up I have ever owned from Logitech. Speakers are crisp and clean, lows are low and highs or high. I use these while gaming, as my PA speakers when I'm making my style of music(electro house) on FLStudio and mixing while using my DJ Pioneer DDJ-800 controller. Thanks Logitech for making such a fine product, and never discontinue these great speakers. Thanks

These speakers sound awesome. They are really loud.

Excellent speakers. Deep bass for the size and loud enough for most uses.

Speakers are loud and crisp! The only downside is you cannot use it for phone calls.

I only have one device that added a slight hum and after adding this isolator - it just went away. To be honest, I don't know if it was the older speakers or the headphones I was using but it fixed the problem. [I have received this product in exchange for my honest review.]

small compact direct box used for eliminating hum in powered speakers. a must for all musicians/dj's. great price.
