I like this boombox. It is just the right size, has good quality sound. Easy to use.

I was looking for an affordable rechargeable portable little cd radio since I bought a car with no cd player. Got an AUX cable for the speakers to, but I tried this little beast just on it's own with a Busta Rhymes Genesis CD and was blown away by the quality. The bass is great, and I love walking around with this thing now at home, it feels like I have a old school boombox with more modern aesthetic. My only beef is I was disappointed with the USB function of this. I hoped there would be a menu like UI so I can easily navigate my MP3 collection of music but unfortunately there isn't so it just goes song by song of your USB with no titles just track numbers so it renders USB music use pointless if you have a huge storage device. Lastly my other criticism is one design flaw imo. The CD tray is nice and strong and it feels safe and strong to walk around with while it plays CD. I just don't like how on the back the CD is exposed with an inch crack so its not sealed airtight, so I may worry about collecting dust or whatever if I am outside too long. That should be covered so the CD is protected better. BUT FOR THE PRICE THIS IS STILL AMAZING. I MAY BUY EXTRA FOR OTHER USE.

Purchased this Klim B4 boombox as a portable adjunct to my larger home units based on the excellent reviews and the product description. For the most part it is an excellent product except for one detail which I will get out of the way now - occasionally the CD skips during tracks even on clean undamaged discs. I contacted Klim (which includes a 5 year warranty - good move!) and they promptly sent me a replacement at their expense. However there is some skipping on the new unit albeit not as much so I will live with this. The CD player by the way is top loading which I find better than the tray or slot-in players that have flooded the market. That said the sound is fine and the front digital display shows both the track number and the timing of said track. However I am pleased to report that the B4's other features are outstanding. Let's star with the remote. When i saw this little remote I seriously wondered whether it was truly a full function remote. I can happily say that it is. It controls all functions and lets you seamlessly go from one to another in a flash. You can also use the numerical keys to select radio stations and the B4 will automatically remember the last one you had on. Both AM and FM reception is flawless - the antenna though must be pulled up first before you can rotate it - be careful here. The Bluetooth function works just fine with quick and easy connection and sounds fine. The downside is that there are not track numbers displayed - you must refer to your phone or tablet for this. The unit has duplicate controls on top of it on the right and left. I personally find the remote easier to use though. I have not yet tried the USB so cannot comment- the port is on the right side of the unit. The B4 is solidly built of very hard plastic and has a large carry handle making it easy to transport. One huge plus with this product is the built-in rechargeable battery. You do not have to remove it - just plug it in to recharge and it is ready to go. I wish other portable boomboxes had this feature. Soundwise the unit is fine for its size - you won't raise the roof but the volume is more than adequate for a medium sized room and there is a sound adjuster for various modes of music which help a bit but don't make a huge difference. There is no cassette player but for me not a deal breaker. So I would rate the Klim B4 a safe economical bet for a portable music unit. Hopefully the CD won't be an issue - if not then much enjoyment should be had from this unit. And the 5 year warranty is a plus.

After a disappointing experience with a similar Sony unit (would not run on batteries), I decided to try this unit by KLIM instead. First of all, it's roughly 2/3 the cost of the comparable Sony stereo, yet has nearly the same features. This stereo functions just fine on either cord or battery power. The LED lighting around the speakers is a plus for us, as we bought it for our son . . .and he loves anything that lights up. They softly pulse different colors as music plays, but there are no user controls which allow you to dictate what colors are displayed. It just runs through a sequence of different colors. Still, it's a nice feature, and my son really likes it. The display/fit-finish of this unit lacks a bit of the refinement of the Sony, but it makes up for it by WORKING. It seems pretty durable, which is important given that we bought it for our 11-year old son. Sound quality is good, for a stereo of its size and power. Connectivity has worked fine, with Bluetooth as well as via the AUX cable input. It doesn't seem to get very good radio reception for us, but it should be noted that we're rural, and live in a bit of a depression. . . so it may not be the fault of the stereo, and we didn't have very high expectations for radio reception in the first place. We just pipe FM into it thru a mobile phone when he wants to listen to the radio. Lastly, the documentation the unit came with included a hilarious little note from the manufacturer, which brought a smile to my face. I don't want to ruin it for other potential buyers, but it was a nice touch.

I wanted to like this product and gave it a chance and then decided to return it rather than risk keeping it and dealing with some presenting problem on long term. I purchased this primarily to play a collection of old time radio CD-R type disc. It did not play the old time radio disc that were recorded on DVD-R which is understandable since the product description states CD-R and not DVD-R and a internet educational search says material recorded on DVD-R will not play on a CD player that plays CD-R. Moving on I inserted some CD-R disc of old time radio and it played them mostly well enough BUT on some it would freeze and the player would not respond when other buttons were pressed and I would then turn it completely off and then it would go back to normal and play. This was of concern and one of the major reasons for the rerturn as I mentally started to forecast having to deal with this unpredictability of playback in the near future after the 30-day Amazon return policy expiration. There were also some features of the product which I also did not like and contributed to the return. I would have dealt with them but those issues, coupled with the aforementioned playback issue added to my irritation with the product. One of these issues was the lighted display window. The window display is extremely bright and can light up a whole room. When the product was facing me if I closed my eyes the light was so strong and bright that I could still see the brightness with my eye lids closed. If I turned the player around so that it was not facing my face it would cast its bright beam onto the opposite room and make the room bright blue. I checked the player manual and although it flaunted the brightness of the window display it did not give any instructions of how one could either turn off the display window or at minimum reduced the unusual and outstanding glare; yet another irritant is that the product description mentions that its power source is lithium battery and an electrical cord. Perhaps I was a bit ignorant when I thought that this meant that I would have the option of using either battery or electrical cord but upon discovery of the product it turns out that there is no such option in the power source. It operates solely on lithium battery and the electrical cord is ONLY to power up the lithium battery. If this had been mentioned clearly I would not have purchased as I am weary and cautious on having any products that operate on lithium batteries due to the mass media reported fire incidents involving lithium batteries. As if to acknowledge that the manual is filled with cautions on the fire hazards of lithium batteries. Again because of the notoriety of the lithium battery I feel that this is significant enough for mention of this to have been made in the product description. The manual also says that the lithium battery can not be removed so there is no alternative. Once I decided to return the product as if on queue Amazon informed that although they say in the item description "free returns" that so-called 'free return' would not include UPS picking up the item at my home and that I would have to pay (to Amazon) 7-odd dollars for UPS to pick up the item at my home. So I opted to accept the amazon free return label and took the item to a UPS direct - this meant of course that I had to lug a somewhat large and slightly heavy box across town as there were no acceptable UPD access points in my immediate area - and coupled with that internet research is cautious on UPS Access point services as some do not scan the item and do not give receipts so that although I will assume that some do the fact that some do not would mean me having to either make multiple phone calls or lug the item around in speculation so I thought it would simply be easier to just lug it to a real and proper UPS store. But i made it a day and had a nice breakfast in the outing and since then Amazon has received the item back through UPS and I have my refund. If you do not mind a player that can be temperamental in playing or not playing a disc and freezing unexpectedly and you do not mind an ultra beam lighted display that can light up a whole room and you are ok with lithium battery and are not put off by misleading product description then on the plus side when the product did play a disc unterruptedly if did play beautifully. However those singular events were not enough for me. So it gets one star for not playing a disc consistently and freezing and for the ultra bright display window light that can not be turned off or dimmed and the electrical cord not being described as only to charge the lithium battery and that you can not play with the electrical cord alone and for Amazon not providing for UPS at home pick up without a charge. Therefore, caution to the buyer

The radio looked nice but I end up returning it. I was not happy with the quality sound of music but for a little over $100 what do you expect? I guess it was my fault.
