Review on KLIM CD Boombox Portable Audio Player with FM Radio, Rechargeable Battery, Bluetooth, MP3, AUX, Neodymium Speakers, and Upgraded CD Laser Lens (2021 Edition) by Ronnie Segobiano

Anyway, it's great. Klim has obviously put some thought and quality into this little device. I believe this is the only product of its kind and design at Revain that comes with rechargeable, user-replaceable batteries. This is a much better solution than the proprietary built in, non-removable battery. The device charges batteries when plugged in, which is great. The sound is clean, clear and pleasing to the ear. This is not a BOOMBOX! It's a small, high-quality device with a solid build for a personalized listening experience. With only 4 watts of power, it's not designed to shake pictures off the wall. The headphone jack works very well. You can connect this unit to a larger system for extra volume via the headphone jack if needed, but that's probably not the best use of this port. Bluetooth works fine. AUX is ok. I put a micro SD card with MP3 files in the USB adapter and that worked great too. My only problem is that, at least on my unit, the RBG lights cause very little interference when they're on and I'm listening through headphones. . I just turn them off and everything is fine. Light does not interfere with listening through the device's built-in speakers.
