KLIM is a great product.
A well designed compact product that sounds good and offers features not found in other similar products. I was surprised by the product features and how well they work. I plugged in a USB Apple iPod and it worked perfectly, playing the music that had been stored. The remote is really nice as well. The rechargeable batteries are a plus during our occasional power outages.

JUST WHAT I NEEDED
I received my Klim Boombox B4 CD Player/Radio just yesterday, so I'm still just learning how to use the controls. My first impressions: 1) I was expecting it to be smaller, so was very pleased to see it was just the right size for my shelf; 2) The sound quality is very good... for both music and talk radio... but wish I could turn the volume up a bit higher so I can enjoy it while in another part of the house; 3) The simple design would work well with any decor. Those are the pros. The only con I've found so far is the small blue light indicating the battery is charged (it remains on even when I'm not listening to anything) is so irritatingly bright I had to cover it up with electrical tape. For the price, this is a fine little unit, and I made the right decision in ordering it. P.S. I got a kick out of the cartoons that went with the "thank you" for ordering this Klim product. I appreciate a company with a great sense of humor! :)

Great except for one thing
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.

S picking
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

A great boombox! It originally came without a remote control but the seller came through instantly and made it right, sending us a replacement before we’d had a chance to send the original unit back! I wish all Amazon sellers were this responsive! The boombox itself is terrific and the remote means my son can turn it off easily.
