Saiyin Bluetooth Bookshelf Speakers, 30W X 2 Powered TV Speakers with 3.5 Inch Woofer, Turntable Speakers with OpticalAUXRCA Input for PC and TV

The Saiyin Bluetooth Bookshelf Speakers are a great option for those looking for an affordable yet decent quality speaker system. The speakers are self-powered with a total power output of 80W and have a 4-inch woofer for a significant bass boost. The bookshelf speaker size is relatively compact at 5.9*6.7*9.4 inches, and it comes with volume and mode switch controls on the top of the unit. Users can also use the provided remote to control the speaker system. Another significant feature is that these bookshelf speakers will work with a turntable with or without a built-in preamp. With a 3.5mm to RCA cable included, connecting the speakers to turntables with RCA jacks or preamp will be a breeze. Moreover, users can connect this speaker system to TVs and computers through the optical input and auxiliary input. The product has received mostly positive feedback from customers. Users have expressed satisfaction with the sound quality, particularly for the price point. The speakers worked well for vinyl turntables and have a good bass response. However, some users have reported Bluetooth connection issues, but the seller provides great customer support and offers solutions to ensure a better connection. On the downside, the subwoofer tends to overpower the treble, resulting in muffled sound, and there are no clear options in the remote to adjust the treble.
