Review on Esinkin Wireless Bluetooth Receiver with NFC Technology, HD Audio Adapter 4.0 for Home Stereo Music Streaming System with 3.5mm AUX and RCA by Brandon Boones

I've been looking for this handy little bluetooth receiver to upgrade my old stereo to the latest 21st century technology. I just plugged this thing into my receiver's AUX input and my stereo was instantly Bluetooth enabled. The connection was easy and fast. The box includes a power plug, a 3.5mm stereo cable and an RCA cable. Nothing more to say except that it works! Update: The volume has dropped significantly. I didn't know about this for months until I used a different Bluetooth receiver. I was amazed when I turned on the music through the phone. I had to turn down the volume. In both cases, I have full volume on my smartphone and about half volume on my 15-inch Gem Sound-enabled speaker. Esinkin's volume is noticeably lower than the other Bluetooth receiver, or it's just perfect while the other cranks up the volume. In any case, I will keep the other one for myself and give Yesinkin to a friend or family member. A few days ago I sent the DAC back for the same reason, a noticeable drop in volume when plugged in. Better without.
