Great sound, reasonable price

All of my old CDs sound so fresh now playing by CFD-F10.  You don't have to pay much to get a good CD player.  Thanks to the reviewers - your comments really helped me to make decision for this purchase.

These are such a great deal, the sound quality is amazing and so is the battery life.  Such great quality at a reasonable price.

These little speakers were great value ($130/pr), are quite attractive and well built, and most importantly deliver very nice clear sound when playing playing music (jazz, classical, popular) and movies. They are of course, short on bass (due to their size). They replaced a pair of JBL 3way floor speakers which had better bass, but weren't quite as good in the upper frequencies. I needed the speakers off the floor and away from my babies.  I wouldn't call myself a high end audiophile, however, though I do appreciate good sound and I am not willing to pay top dollar (yet).

Fantastic, booming sound for a very reasonable price.  This is the kind of quality/value that makes you want to buy multiple so you can have one of these in many locations!

Using these primarily with my docked laptop, with the added enhancement of better converters via a Filo E17K DAC (which I've used on everything for a couple years now. Highly recommended).

I'm an audio/recording engineer in my free time, and very particular about sound reproduction (short of spending the money to be a true "audiophile.") I love great sound, and these speakers deliver. Very warm, full, pleasing sound, but no hyping that could cause listener fatigue.  I doubt there is anything of this physical size that will significantly outperform them, and certainly nothing close to this price point.

After my rabbit ate the main cord of my son's 6 way speaker system for his desktop, I decided to get something smaller that could sit up high right next to the monitor.  These speakers have a great sound, are very easy to install and were an extremely reasonable price.

This amp is incredible, great sound at a reasonable price. It's compact and light enough to make mounting it a breeze, the amp is holding up quite well to the abuse and elements in my jeep.

After receiving my headphones I've listened to quite a few different genres of music (electronic, jazz, post hardcore) and these seem to handle them all very well. Audio is crisp, clear, and bass comes through nicely (but not overbearing). They fit comfortably and are adjustable so if you're wearing a hat or have a lot of hair it shouldn't be an issue. Color is slightly different from the pictures, but very, very close. The braided cable is excellent. They aren't exactly the top-top studio quality, but in terms of what you get for the price they are far better than a lot of what's available right now from other brands. They sound great, they're comfortable, they look good, and they are priced fairly. Plus being able to fold them down for travel is handy.

I've had these speakers for several months now and I love them. They are the best sounding $30 speakers I've heard and do not regret purchasing them.  If you are looking for high end speakers with lots of features, look elsewhere.  But if you don't need audiophile, high end speakers and just want an inexpensive, but good sounding set, you can't go wrong with these.  Below are some things I like and minor issues that weren't a deal breaker for me.

What I like:
- They go plenty loud for my office setting.
- Bass response is good but not overpowering
- Have a nice, rich sound, especially for the price.
- Volume nob is easy to adjust.
- Relatively small footprint.

Minor problems:
- Cabling a bit short
- No bass control
- No headphone jack

Long story, short: Good quality, great sound, reasonable price.

I purchased the red version because I wanted to skip white ear buds, which become discolored and show dirt after a while, and for some reason the black version is more expensive and not eligible for shipping via Amazon Prime.  I'm assuming the black version is identical in sound and quality.

First, the fit.  The packaging includes three different sizes of bud attachments.  I use the largest size.  The buds are soft, and fit comfortably in my ear.  I completed 30 minutes of vigorous exercise on the elliptical machine and 45 minutes of weight training and the buds remained comfortably in place.

Next, the sound.  The ear buds handle low and high range frequency very well and there is a full, warm balance throughout the mids.  Both my iPod MP3s and highly-compressed Pandora streams sounded great.

Finally, the price. You get good build quality and great sound for a reasonable price.  I'm not sure why people pay over $100 for ear buds anyway.  If you find yourself mixing an album, listening for extraterrestrial communications, or trying to discover new low frequencies with Dr. Dre, you shouldn't be using ear buds anyway. Your dog may be disappointed with the few high frequencies these ear buds can't reproduce, but most humans should be fine.

These work and sound really nice for their price range. I am very impressed. The service from Amazon was swift and sure. I think very highly of Amazon. Back to the speaker system....They are currently in use in my apartment, and are very suitable for apartment living and listening to music at reasonable levels. In fact, i have the bass volume turned all the way down, and it provides enough 'oomph' for the rock and jazz I listen to. The mids are a little weak, but this can be expected of 2-way systems in this price range. The bright blue lights were a bit of a shock, but I am getting used to them. A drawback is that they are made in China, and all that that implies. But I will keep them, despite my feelings about sending money to that country. I like the speaker system a lot, and like their sound. They cannot do what studio class monitors do, but, hey, like it was stated....So, if you are looking for a 'good bang for the buck', and can stomach sending money to China, these are a great buy. Hookup was easy, and the sound is pleasing.

SOUND IS AMAZING, EASYILY FILLS MY LARGE LIVING ROOM WITH VERY CLEAR SOUND AND GOOD BASS. AND FOR THE PRICE I WOULD BE HAPPY PAYING MORE.

Great sound, reasonable balance especially for the price.  Comfortable fit.  Nice appearance and good sound blocking.  Cords don't tangle as much as rubber cord, but seem to develop a set, when unrolled, they have loose curls.

I've been using these speakers since I purchased them years ago. They were very reasonably priced (~$90 when I purchased them), have bluetooth capabilities with plug-in ports as well. The sounds quality is good and they also contribute to a more surround-soundesque environment when placed on both sides of one's monitor(s). Great product for a great price

This is my second pair of S4-II headphones. First pair lasted nearly 3 years with nearly daily use including running at least 3 times per week. Great sound at a very reasonable price. Can't go wrong with these.

I was actually pleasantly surprised by the sound quality of these. They're not great, but very usable, and more than acceptable for the price. There nice bass, voices are quite clear, and music is enjoyable, with no buzzing or tinniness. The sound quality actually isn't very inferior to the Logitech Z523, which cost more than double.

One drawback is that the volume control doesn't apply to the headphones - the headphone signal isn't amplified, just passed through, so if you need some more power to the headphones, or an independent volume control for them - look elsewhere (like the Z523).

If you just want an inexpensive speaker set - go for it.
