So, the reviews on this little player were very encouraging. I bought it, and even though the price is a little high, the boombox plays great and sounds fantastic. So far, I have had nothing but enjoyment when listening to my CD's on this little player. There are a few things that I would have liked to have on this. For example, the player displays the track number, but only for a few seconds, then it just shows the time of the song. If you have to pause a song in the middle, then it will only hold for a few minutes, before shutting off. The problem is, the player will not continue where you left off. So, unless you know what track you are listening to, good luck in continuing where you left off. Also, it doesn't say how long the total CD time is. Also a few other problems with the display. Nothing major, just a few things they could have improved on, but didn't. I do give it 5 stars, as the sound and sturdiness of the CD player is fantastic. So overall, a great player. A little pricey, and the digital display, could have been better. But, if you want a sturdy, well-built CD boombox, then this one is definitely a great choice. I just added this- I had a wonderful time with the customer service. My player was making a small hissing sound. So they sent a new one. Now they both play great, it's just the one that has hissing. Well, they sent a new one and told me to keep them both. That was extremely generous of them. The hissing is only noticeable when the music is not playing, and the player is on. When the music plays, then the noise is impossible to hear. So I have an amazing player in the one unit. And a slightly less than a perfect player in the other one. They were very kind and friendly. Great company to do business with. I will definitely do business with them going forward. Thank you to the Klim company. Review: Couldn't connect to bluetooth until... - I bought it as a gift for my wife and it sounds so good that I bought a 2nd one for me. Good sound quality, BUT... I cannot connect either one of them to bluetooth. My phone connects easily to other BT items, but will NOT connect to either of these units and THAT sucks vinegar through a paper straw/ UPDATE; AFTER BEING CONTACTED BY klim CUSTOMER SERVICE AND OFFERED A FULL REFUND, I declined the refund and they worked through a few troubleshooting options, but it still would not connect. In summary, my phone was not updating firmware automatically. I updated my phone's firmware and ((SHAZAAM!)) it connected to the KLIM bluetooth immediately. This review started at 3 stars, ending at 5 stars for product quality and some awesome customer service. ## Features - PORTABLE CD PLAYER: Enjoy powerful bass and crystal-clear sound from this compact and stylish boombox thanks to its quality componenets. - BLUETOOTH CONNECTIVITY: Stream music wirelessly from your smartphone or tablet.

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. ## Frequently Bought Together - KLIM Boombox B4 CD Player Portable Audio System - New - AM/FM Radio with CD Player MP3 Bluetooth AUX USB - Wired & Wireless Mode Rechargeable Battery - Remote Control Autosleep Digital EQ - Sony ZX Series Wired On-Ear Headphones, Black MDR-ZX110 --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/508732618-boombox-b4-cd-player-portable-audio-system-new-am-fm](https://www.desertcart.jp/products/508732618-boombox-b4-cd-player-portable-audio-system-new-am-fm) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-04*
