It looks cool and saves space. It sounds great for radio of this size (slightly larger than a book shelf speaker). Good bang for the buck for $40 you get a good deal. The woofer on the bottom is like 4-5 inches approx. so don't expect super deep base like something you would get from a 10 or 12 in sub. Balanced sound to fill a room or office / garage work area. The FM antennae is good and channels are easy to use. If this were say $150 I would be disappointed in the sound quality.Pros *Price *It looks way cool/digital tuner display, and exterior *Sound 1 woofer on bottom 2 speakers on front *FM radio, portable internal recharging battery. *BluetoothCons *Doesn't sound like hundred dollar plus Boston Acoustic, Polk or Alpine Speakers. *Begins to bottom out at top volume and base *Sound is not as rich as a more expensive stereoIt gets 5 stars because it is good value for what you pay for it. Meets and exceeds my expectations at this price point. ### ⭐ 1.0 out of 5 stars like all the time *by L***K on Reviewed in the United States on April 11, 2017* POS!!! I work over in Africa, so I bout this to have some tunes playing through the day while we work. First hour was ok but every since then.. the speakers are distorting....like all the time! I thought the "bass" speaker was blown so we removed it and had a look. It was not blown, but sounds like it is all the time! I really hate that I spent this money on suck a crapy product! The jam classics were better but i was just trying to get something that was a little bit louder.. Well, NEVER AGAIN! ### ⭐⭐⭐⭐ 4.0 out of 5 stars Hmmm... I like it... I like it a lot ... but...? *by G***R on Reviewed in the United States on October 30, 2015* First off - it's small. About as big as a dictionary... Thought it would be bigger... Feels a bit light and maybe flimsy - like it might not survive a drop. But I'm not planning on dropping it so...The sound is more than decent. It's pretty good, over all. Two speakers on the front plus a pretty decent display - letting you know you're in Bluetooth or radio mode - and displays the station. When you power the unit on, it defaults to the FM radio. You need to hit "MODE" to get to Bluetooth input.There are a USB input and one for the SD card and an AUX in (earphone jack). plus power in. And an assortment of buttons for different functions. There are a few built-in EQ settings - maybe a half dozen presets. There's also a separate bass + and - control, which is nice.The carpet covered box is good and keeps it from being "buzzy" with too much plastic at higher output levels...Good for a smaller space - a room or two, back yard, and the like. Much more and you'll probably not be able to hear clearly. Speakers are not made for high-volume... they get a bit rattled at top volume levels of both the speaker and your device. ## Frequently Bought Together - Sondpex CSF-D45B Portable Bluetooth Speaker System and Music Player - Clear Sound, Deep Bass, 12-Hour Battery, USB/SD Slots, FM Radio - Stream Wireless Music with EQ, AUX Input - MP3/WMA Support - Soundcore by Anker Life A1 True Wireless Earbuds, Powerful Customized Sound, 40H Playtime, Wireless Charging, USB-C Fast Charge, IPX7 Waterproof, Button Control, Bluetooth Earbuds, Commute, Sports - Honeywell Turboforce Fan, Ht-900, 11 inch --- ## 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.ec/products/13319391-csf-d45b-portable-bluetooth-speaker-system-and-music-player-clear](https://www.desertcart.ec/products/13319391-csf-d45b-portable-bluetooth-speaker-system-and-music-player-clear) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-09-18*
