These do have a surprisingly good clean sound.They are good replacements for built in laptop speakers.They sound better than most built in monitor speakers.They do not not sound as good as headphones.These have a surprisingly wider range than expected, from the lows to highs.Bass doesn't hit hard, but it doesn't distort at lower to mid volume ranges either.At maximum volume, these speakers will start to distort and sound like garbled, but that is expected for the small physical size.Overall, these are made for easy listening. They do a good job. The decent quality matches the price point extremely well.These however are absolutely not for gaming, so don't expect that out of them.Also, the lead USB wire is kind of short, like 3 feet.

The bass is for those that love bass. Intense and soothing

I've always liked the Bose brand and the sound it reproduces. Let me explain that I am a musician and have a great deal of experience with sound design and audio production. Too many speakers or sound designs are made to enhance the bass end of the sound envelope, especially to enhance the sound of an impact. I wanted a speaker that would add to the depth of the sound for our television without adding too much bass. Most people think they need a sub-woofer when, in fact, a speaker like this is perfect for their needs. I bought this because it did not have a sub-woofer and it is perfect!! It still offers great sound quality without too much deep bass from poor sound design of television shows and films. And you can always turn that bass up or down. I've waited a long time to get a decent speaker because I wanted control over the bass, with a good range and depth of sound color, and the added bonus that people's speaking is very distinct. It's all here.

Have had these for a year. They are impressive for the price. Great bass. Mid range is lacking and bass is ever present even when it shouldn't be. For the price, they kick ass.

These little speakers put out excellent sound!! I was skeptical but when they finally arrived and I got my phone hooked up to it. I was extremely surprised on how clean and loud the music was. The bass was deep and very loud. Some songs the bass was a little too much but it is easy to adjust and balance the bass. I intended to buy the logitec so I could quickly hook-up my phone to it and listen to new music since my Yamaha receiver didn't have the proper plug-ins. I have a pair of Bose 301 on the Yamaha receiver. The logitec Z623 sounds much better and definitely louder. Its high frequencies and bass really out performs my 301 Bose. The mids are comparable but when the volume is cranked the logitec keeps on going and I can fill the room with extremely loud and clean music. I have to turn the bass down some at high volume to balance sound. I can only get half the volume on my Bose 301 before the start to distort.

Bought these speakers for my desktop computer. After 17 years my old speakers died and I wanted something a bit better, something that can pick up better bass. I thought a woofer was overkill for just a computer but they were cheap and I liked that I could control the bass and volume right from the one small speaker. Hook up was quick & easy. The woofer is HUGE but nice looking enough to where it doesn't stick out. I'm a record collector, sound is important to me, and I'm very picky with how my music sounds as well as plain spoken word audio. This set impressed me. 2 tiny speakers and one big woofer and the quietest soft rock seems to blow the room away. It's not muffled, it's crisp and clear with the right balance of bass which can be controlled via a dial on one of the smaller speakers. The one small speaker has a volume and bass dial and and on/off push button along with a light to let you know the system is on and running. When you crank the woofer you really hear it--every single bass note, like listening to music for the first time all over again no joke. I also watched some video of a tv show and the sound is awesome, you hear every single thing, as if you're at the movie theater, in one scene some guy punched someone else & it sounded like someone dropped a piano on my roof--BOOM. I'm planning on buy another set for my television, I honestly can't imagine not hooking it up to my tv. I'm at the point where I'm jealous of my computer and want it on my television for movies. I'd buy one to listen to vinyl records with if I knew how to hook it up to a turntable. It really is a very good system. I've purchased other Logitech items in the past 10-15 years including a webcam, mouse and keyboard, never any issues, good products.

The style is kind of cool, with the sphere thing. I find the sound to be very satisfying and full ranged. Plus you can adjust the 3-band EQ (bass, midrange, treble) to your taste in the app. The bass quality is quite good, but when you get to a party-time level, the speakers will pop, even with the bass set to center. But even worse is any kind of hip-hop or anything with a deep bass beat -- they will it make it pop (crackle/distort,) even at fairly low volumes. Also I have found Alexa to misunderstand me a few times, even though I was close to the Echo and speaking very clearly. The number "nine" must be pronounced long and clear or you'll get "that was incorrect" (if you're playing a trivia game, for example.Overall, I like the Echo a lot, and enjoy it's rich sound. Despite a few flaws, it performs well and is a great addition to any room.

These are probably as good as bluetooth speakers get. The stereo pairing is great, and you do get true stereo. Unfortunately, the one thing I really wanted to avoid because I'm sensitive to it, is bass distortion. I would say this happens within the normal loudness range. Maybe this is inevitable in compact bluetooth speakers, as I've experienced it with my previous two. I know this problem seems to get steadily worse over time. If I notice it getting worse in the next few weeks, I won't hesitate to return them. The problem with distortion occurs in stereo mode (with two speakers) where all the base is on one speaker. If you run in dual-mode, this doesn't seem to happen.
