Question: I bought these speakers and they constantly buzz when there is no sound output. Is this normal or should I exchange them?
Document: These things sound better than they have a right to for a 2.0 system and the $45 I paid for them. Yeah the bass isn't going to shake the windows, but be real, this price range speaker isn't designed for that, nor should that be expected.That said the bass isn't exactly lacking either. The treble range is clear and clean. I bought them for what they were intended for. My expectations were met.It's not mentioned, but the connecting cables do come with the speakers. No need to buy anything additional.
Let me start by saying the price and brand name are misleading. These speakers ROCK! I own a surround sound system that's hooked up via optical cable but wanted something compact for simple listening when I didn't want the block to hear me. I did a lot of research into cheap sub $50 stereo speakers for my desktop computer and stumbled onto these. I bought them outside of Amazon second hand and they are still amazing.Pros: Their sound reproduction is phenomenal, I'm a music buff and they hit the lows, mids, and highs VERY well.They aren't the smallest but are not big by any stretch either, height and horizontal are the same as my Nexus 7 tablet with minimal depth.They have a LINE IN!
Just received one of these. First day, the second speaker pooped off in sound as if the connection was lost until I had to turn off the power button and then turn it back on. The connecting wires are very flimsy compared with even a cheapo keyboard wire. The sound was sufficiently loud and decent until the 2nd day, where once you pass 33% of the volume dial, the buzz fuzz noise is fed through as its natural state. If it wasn't the buzzing that's generated, I would have been fine with the flimsy wiring.
These speakers are truly great. They have good sound, nice bass and are really good looking.I can't find a single thing wrong with them! FIVE STAR!
Purchased for an executive who wanted better quality speakers, they look and sound awesome. He was a little surprised at the size but I told him you have to have some size in order for good bass response.
Very good sound for such small speakers, and I like that sound is warm. Main speaker is very heavy for it size, so I think there is good amplifier. I lke these speakers, they definitely cost their price.
Plug these into the wall, then plug in your ipod and the sound will blow away most docks.I haven't reviewed many things, but these speakers are exactly what my desktop needed. I listen to a lot more music now - and that's a great thing.
I am using these speakers with my ipod and ipad. They sound like high end audiophile speakers. Very transparent and detailed sounding. Best $36 I have ever spent. I think I will buy a few extras for other rooms in my home.
I wasn't looking for top of the line sound, just something nicer than my old computer speakers. These deliver. No distortion, decent bass, and when I want to use them for my TV, its a simple matter of popping the jack into the Line In port. They look really good too.
These speakers are the perfect size for my computer setup. THey handle music and sound perfectly, MUCH better than I had expected from them. I recommend these speakers to anyone who doesn't have a lot of room for placement and who wants a great sound with no distortion. Well worth the money ... thank you again Amazon !! !
Answer: This is not normal. I have the speakers and they do not buzz when there is no sound output.
