Using the 3.5" connector at lower volumes, the music fades in and out and the electronics noise is often louder than the music.

There is a hissing noise when nothing is playing but you do not hear it when it is in use

My only gripe is there is a very very minute static white noise in the background when using bluetooth on low volumes, which is common on all bluetooth speakers.

However, after pairing to my cell phone and the streaming started, a very annoying mid-high frequency electric noise popped up

The static noise was not there when I plugged in the aux cable.

Unfortunately, the third speaker also has significant electronics noise (also noted in reviews written by others) after a few weeks of use.

did not work well at all.. could not disconnect from wall plugin.. low sound, scratchy noises.. if you pass between the speaker and a bluetooth device

I cannot charge and play the Kindle using the BT speaker at the same time due to a terrible humming noise...probably a ground loop, and noise still there if the Voom is unplugged from its 15V supply.

Unfortunately the speaker I originally purchased began having sound quality issues when connected via Bluetooth (sound would dip in & out with slight hissing noise, which is apparently the same issue as other users have posted and related to a bad lot), but once I contacted customer support they were very helpful and wasted no time in shipping me a replacement.

horrible came with weird noises when i play over bluetooth

Product emits a loud buzzing noise

Hissing white noise when playing anything

The reason I knocked off a star and sent it back is because when connected to Bluetooth I could hear a static white noise

When no music is playing there is significant white noise that comes from the speaker

The "hissing" or "static" noise is there at low volumes

Loud hissing noise on bluetooth connection

It rarely can charge without lots of finicking and makes odd noises when finally turned on.

but I still hear a whine/buzzing/white noise between songs.

Great speaker sturdy and beautifully designed, bass is thumping it has a rich powerful sound no hissing noise no issues whatsoever..

Weird static noise at low volumes, I suggest turning the volume on the speaker down and the volume on your audio device up to reduce static, also I blew the speaker in it within the 2 days I've had it lol

This can be a nuisance for many, but for myself, it did not bother me much, especially since the audio tended to overshadow the static noise at medium to high

Using Bluetooth, the electronics noise is unacceptable at any volume level.

I notice complaints about static noise, hiss, etc

I've had $20 speakers with better sound quality, and there's a constant low humming noise it makes when on that drives me nuts

I work outside and deal with loud noises

My first VaVoom 21 made loud and strange noises when changing functions and sometimes did so at random

One thing to note is that there seems to be some kind of static noise in the background when audio is playing.

I concur with other reviews that there is an annoying background noise during any silence or soft sounds

While the sound is great at higher volume, there is a constant hissing noise that becomes noticeable at lower volumes

When connected to the AC power supply there are definitely some static noises in the speaker

However, it makes an incredibly obnoxious hissing/crackling noise when paired with any bluetooth device and plugged into the wall to charge

We recently went to Costa Rica & at the resort we were at, I would take it to the pool with us & it would really rock easily overshadowing all the poolside noise.

For it's small size, this is one great sounding speaker, loud n' clear and has a great dynamic sound, which will fill rooms of any size with ease

They gave me all the items included and speaker was nice n' cozy right out of the box

Remember you definitely cannot listen at a high volume the bass blows out immediately especially with heavier, dark music.(slipknot, Deftones, juice, korn, especially type o negative, lamb of God definitely a no go)

I'm very demanding of my sound waves so I could very well be the problem
