Sound is good, lacking some features

The quality of sound is good.  The problem I have is with the settings.  I think the settings can be more user-friendly and intuitive.  Secondly, I am surprised not to find a RF antenna input.  My idea was to hook this up to an indoor antenna and projector to watch sports but now I will have to buy a digital tuner extra to convert the RF coaxial to HDMI input.

Sound is good, but not superb, I love the controls! The battery life is crazy good!

It gets only 3 stars because the noise cancellation is seriously subpar.

I wear these comfortably at the Gym, and my hope was that these would mean I could block out "Planet Fitness' " radio channel, with it's bad music, without having to destroy me own ears with high volume. Alas this was not to be, the headphones noise cancellation seems to do little to nothing to tame the moderate volume of the Planet Fitness speakers.

I generally enjoy this boombox. The main feature that sold it to me is the tape player, I want to listen to my old tapes. It also comes with a dedicated input for MP3 devices. The price is very reasonable. The sound is great but not the best, it is powerful enough to fill a large area. The only issue that bothers me is that the bass boost makes the low notes distorted, so I don't use it. I don't know if the cheaper model also has the MP3 dedicated connection, because if it does then it is very much worth to get the cheaper model since the bass boosting feature on this model is not worth using.

The keys that one presses to play-pause-forward, could use better labeling, they are hard to read/see because they have the same color as the plastic (all black), therefore, until the keys and their locations are memorized then one has to spend a few extra seconds trying to locate the button one needs.

Good sound! But short on convenience features. E.g., it'd be nice to able to remotely control volume, like from an app. Bluetooth is spotty. I use it better as an AirPlay speaker, but loses stream during quiet passages, then annoyingly "pops" when volume threshold is reached again.

So, far from perfect as a device, but excellent sound.

Great sound, and nice feature in that you can detach it from its external speakers and use it as a conventional CD "walkman."  The controls aren't that intuitive, however, and the instructions are somewhat lacking -- it took me quite a while just to figure out how to turn the thing off!

Pros:
Great Price
Great features
Menu is easy to use
Long battery life
Very user friendly
video quality is good

Cons:
Can't produce clear bass.  I thought at first that the headphones that came with it were just cheap and could not handle the bass the player puts out, but then I hooked up my $150 Pioneer headphones and the problem persisted.  The sound quality is good as long as you keep the equalizer set to classical or jazz.  If you set it to rock, bass, or pop, the sound just gets fuzzy.

If you want to listen to music while reading an e-book, you have to listen to mp3s/wmas.  You cannot listen to the radio while reading a book on this player.  Also, you have no volume or play/pause control while reading a book.  So if someone asks you a question or the music is not loud enough, you have to back out of the book, scroll over to the music player, and select the now playing function just to be able to pause or change the volume, which is a pain.

Also, there is no way to sort by artist and album together.  you can either look up albums OR artists.

All in all, for the money, I would suggest it to others.  All the problems I have with mine are minor and only an annoyance at best.  Still love it.

The sound is good. I'm not able to switch songs from the headset. Which is something I strongly dislike, but I don't feel like returning them. So other than that the headphones are good.

It would help if you had a digital display to see the level and depth of the sound.  The sound is very good!

Sound is good enough. I can kick the volume all the way up and even the loudest bass will sound decent.

Unfortunately, my complains are:

1. The battery does not last much. I have to charge them at least 2 times per day.

2. There is no feedback for the user when I connect the phones for charging. SOMETIMES a red light will turn on, but it is pretty rare.

3. They don't charge when I connect them to the computer. So my only option is to charge them directly with my wall phone charger.

4. When the battery is low, the warning noise is really annoying. Even if I connect the phones for charging while I use them, it won't shut up.

The sound is decent for a portable. It's heavy for its size and a handle would be useful. It doesn't have a remote control, which is surprising considering how expensive it is. A remote isn't needed if your using bluetooth, but it would be helpful when it's in FM mode.

This is a bluetooth mono speaker, and all it's got going for it is its small size, volume/track control buttons, and good battery life. Oh, and the clip/stand.

My quibbles:

Sound Quality - comparable to the sound quality from my Iphone 5, anemic-sounding but better than laptop quality. The max volume of the Pulse is about the same as the max volume from the iPhone speakers, so not much benefit to having a Pulse if my phone can do the same thing. The only positive I can think of is that you can have clear sound playing from the Pulse while the phone is in your pocket (where the sound would be muffled if playing from your phone).

Bluetooth connection - It's spotty. I live in a one-bedroom apartment. I had the phone in the bedroom, Pulse on the bathroom sink counter next to my bedroom (10 ft away at most), and sound was cutting out randomly, even though I wasn't touching either phone or Pulse. That tells me...that a thin wall is enough to interrupt the signal. Disappointing.

Not very useful - If the sound quality and volume strength is comparable to my iPhone, I'd rather just use my phone.  I wouldn't use it to clip on my clothes while I'm walking out and about, because who wants to hear my music blaring out loud in public? I wouldn't use it in my car, because the AUX output uses the car speakers and that sound is far superior to a bluetooth mini speaker. I'd only use it with a bluetooth enabled product that puts out really bad sound, like my laptop. And that's too heavy to carry around so I'd most likely just use the AUX cable connected to my husband's nice speaker system.

Overall: I feel like bluetooth speaker devices are impractical and not very effective, most notably in the sound quality department. The way bluetooth technology works limits the distance you can put between the source and the speakers a great deal and the objects that are in the way affect the continuity of the sound as well. The only times I've used the speakers is when I had my phone in my pocket and wanted to listen to the music without headphones on. But then it's usually a frustrating experience because the sound would cut in and out once in a while. And after trying this product out, no way would I pay $80 dollars for something like this. Surely, if you must get bluetooth speakers, you can find one at that price with better sound and connectivity.

The headphones have the sound quality I expected (quite good) and the wireless feature is nice. However, there are two annoying bugs that I am a little frustrated with. First, the headphones turn off each time they are docked so that you have to turn on the base station and the headset separately each time you want to listen to them. Second, when the sound is very low or goes silent briefly the headphones "skip" a little. This is not a problem for most of my library of music but I notice it when a song is fading out at the end (the headphones will stop playing prematurely once the sound is low enough) or when there is a brief silence in the middle of a track. Overall I like them, but they were not quite as nice as I had hoped.

Purchased both black and blue ones at Fry's on sale. Sound not bad and paired all right with either my mini iPad and the 10" Samsung Galaxy. Confusing at first since it didn't know which to pair with, needed to turn off either the Samsung or iPad bluetooth even when one was rather way farther away.

My problem was using the microSD card and the 3.5mm jack as there is no physical switch provided going from bluetooth to the two functions - needed to remove and reinsert the jack or SD card (this may damage the card circuits) before its recognized and even then its a hit or miss. Its like this on both units. I have a different speaker with a physical switch from bluetooth to mp3 - so much easier. With 7 push buttons, they could have incorporated a method for switching from bluetooth to the other two functions easily.

When paired, the sound was much better than either iPad or Samsung internal speakers - three stars, could have been five were it not for the flaws.

the sound is superb.  maybe not as good as the $300 headphone that i bought a few years ago, but it is close.  the interface feels easy to use.

i just wish:

1. the headphone doesn't use steel as the earpiece shielding, as it may rust after a year or two.

2. there is an easier way to charge the unit even if you are without a USB connection.  when going on a pleasure trip, we may not have a notebook computer to charge the unit.

The Harman Kardon MAS 102 Compact, Integrated Music System is a surprisingly nice sound system.  I would be happy having this as my sound system in a smaller sized room, but Harman Kardon made some curious decisions that dampen my enthusiasm just a bit, especially considering the premium price.

First the positives:

- Fit, finish, and build seem first rate.  The speakers cabinets and CD/radio unit were particularity nice, with a solid high gloss piano black finish.  There were no signs of cracks anywhere (as noted in another review).  The speakers terminals on the amplifier unit and speakers also seem to be of very high quality.

- Setup was pretty straightforward.  The ribbon cable connecting the CD/radio unit to the amplifier unit is a smart way to cut down on cable clutter.

- The sound is good considering the size of the speakers provided.  The overall sound is warm, but there is treble produced when called for.  The treble seems to tail off a bit at the very top end, but I did not find it objectionable.  As far as the bass, it reaches down to about 60Hz as advertised; Harman Kardon seems to have added a bit of boost around 300Hz to make up for the lack of really deep bass, which might explain the overall warm (but not boomy) sound to my ears.  The size of the speakers also limits the maximum volume of the system; this isn't a system designed to produce ear-splitting sound levels, but at more typical listening volumes you'll be fine.

- The iPod dock "Bridge III" dock works as advertised.  Once I figured it out I was able to move around the iPod menus (using the iPod display itself) to select music.

- I also tried the CD player, FM radio, and AUX input, which all worked as expected.  There are a surprising number of inputs for such a small system; the Phono input was an unexpected bonus.

- You can control most functions from the CD/radio unit itself using touch commands without using the supplied remote control.  (I tend to dislike electronics that require a remote to do everything.)  The only major function that requires the remote that I wish didn't is switching between inputs.

And now for the curious negatives I found:

- For some reason the amplifier unit is a charcoal grey, which stands out from the gloss black of the other components.  It's not bad on its own, but I would have preferred it blend in with the rest of the components.

- No AM radio?  Believe it or not AM is still alive and well in 2013.  And the included FM "antenna" (just a black wire) is garbage; I substituted a standard dipole FM antenna like&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/FM-Dipole-Antenna-Male-F-connector/dp/B00B5JK118/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">FM Dipole Antenna - Male "F" connector</a>&nbsp;along with an adapter to match the PAL antenna input and got much better FM reception.

- The tone controls are surprisingly basic - just bass / treble / balance.  At  this price a 5-band control would be nice.

- A system with small speakers like this would be so much better with a separate subwoofer for the really low frequencies, but for all the inputs and outputs HK did not include a subwoofer output.  Why?  (Some subwoofers can take a full-frequency input and filter out the higher frequencies, but it is typically better for the main amp to implement the filter/crossover and have a dedicated subwoofer output.)

- Since there is a nice two line display on the CD/radio unit, it should display the artist / song title for the iPod input rather than just "iPod Now Playing" as it does now.  The display could also be used to assist in navigating the iPod menus, but it is not; remote control of the iPod is worthless if anything more involved than skipping to the next rack requires you to walk up to the Bridge IIIP to view the iPod display.

So in sum, the KH MAS 102 is very stylish, sounds fine for its size, but is just missing a few things that keep it from getting a 5-star rating.

The sound is good. A little awkward to join because of the Bluetooth button location.

The headphones were easy to pair with my iPhone and overall the sound quality is good.  There were a couple of things I wish were different.  First, the "squares" that the earbuds are attached to are heavy.  Any amount of exercise cause the buds to become loose and fall out easily.  Second, it would be nice if there was a button or function that would initiate Siri.  Having to pull the phone out to make a call is inconvenient.  Last is the vibrations on powering down.  When you shut the headphones down it vibrates for a long time, wasting battery and it's unecessary.
