So far ok. I have not figured out how to seat each no. For FM radio. Nice sound 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.

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? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.it/products/508732618-boombox-b4-cd-player-portable-audio-system-new-am-fm](https://www.desertcart.it/products/508732618-boombox-b4-cd-player-portable-audio-system-new-am-fm) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-05*
