Review on 🔊 Dual Electronics LU48BTS Wireless Portable Bluetooth Speakers: TruWireless Stereo, 100ft Range, Rich Bass, 12-hour Playtime – IPX4, No Wires – Sold in Pairs by Jason Sullivan

Reading the reviews on Amazon I thought these were good wireless bluetooth speakers. They are sold in pairs. One of the speakers I received makes a humming noise. Subwoofer Another speaker has defective charging and Bluetooth LEDs. A speaker that produced audio without hum sounded clear and loud, but lacked bass. Probably 3dB lower at 90Hz or higher, even with Artificial Bass EQ on. They had no bass, the bass EQ boost just blew the mids more into the sound, they're advertised as having a 44Hz response - no way. These are very light speakers, £3 each, must have used very cheap drivers. Years ago, Dual was used to make high quality turntables and other audio equipment. Equipment I read in the manual that they are powered by 3 18650 in series Over priced Poor sound quality Large size I am very disappointed It could have been great but seems lacking in engineering or sound quality. I'll send them back as soon as possible.
