Review: Fantastic Portable Music System !!!! KLIM all the way....!! - I'm so glad i made this purchase. After much research and trial and failure i've finally found a solution i can truly claim is exactly what i was looking for. Since this will be my work music-system i needed something clear and capable of delivering music via a variety of media. I won't quite say this is an iPod-killer but it comes close. the USB-drive input is so cool if you don't need to see track-titles or have complete control over how your playlists are sequenced (the random-mode is helpful) USB-drives are cheap so you can have multiple Flash-drives containing a variety of music(s) of your choice (the only limitation being no disks over 64 GB...my unit really seems to like Sandisk). i had no issues whatsoever with CDs skipping....i wish the FM and Am knobs weren't stepped but the increments are tight and i get my favorite FM station clearly. The Volume- knob has 30 steps so you have a very nice range of volume to work with. ...almost twice as much as your mac computer. The audio-input is there if you want to plug in a phone or i-Pod without bluetooth. The unit provides 4 EQ settings plus the default. i've found the Jazz setting to be my favorite...providing a nice clarity across the spectrum for all music. ..it's actually a brilliant little Eq-curve given the speakers.....which is the bottom-line. i won't say this is a 'blaster' or 'boombox' of the sort i'm used to but it packs a better punch with clarity than my 2 old favorite companies' current products in the same price-range. i'm just blown away by this unit as well as the super-folks at KLIM who were immediately responsive when i had an issue with my original unit and immediately sent a replacement the next day. the REMOTE-CONTROL is VERY effective....since some of the work i do means being on ladders several feet away, a reliable remote is essential if i'm playing playlists with jumps in volume or need to skip a track. (in the first photo you can see my little KLIM approximately 15 ft away. i am on this side of the yellow ladder and was still able to to easily get the unit to respond to my remote commands (which i keep wrapped in the original plastic to protect from paint and water). i also think it's important to note that this doesn't sound like a BOSE with truly heft bass....i often work in small bathrooms when people are home so even at low volumes i don't want that much bass....just enough to have things pop and provide some definition. this is a dream unit in that regard.....so whether i'm listening to electronic music or Gordon Lightfoot....the sound is just so very nice... the question becomes how long will it hold up to the abuse i will subject it to?....i'm confident it will hold up just fine...it's build is solid. the package itself is excellent and KLIM throws in cool bumper-stickers.... i don't go around saying how much i love a company but i really love this one. my search is over.....KLIM is my new choice....of course i'd be very excited were they to release a B6-Model.
Review: Good sound quality from a rugged little system - Sturdy and reliable, easy (sot of) to use, and excellent for bringing music to site. I use mine when I'm splitting wood. One CD (usually something like The Traveling Wilburys because you need distraction) is the limit for splitting, and then a repeat for stacking. Loud enough to keep me amused, but not too loud to bother the neighbors (too much). Good battery life, can take a little light rainy or snowy weather.

### ⭐⭐⭐⭐ Great except for one thing
*by J***H on March 7, 2024*

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.
