We are sorry to hear about the disappointing experience you had with your Scosche Bluetooth FM transmitter. The issue you are describing is not normal for a customer to experience with the following product. There is a way to adjust or turn up the volume on the transmitter which is a separate volume control from your Bluetooth streaming device (mobile phone). This will help to get rid of unwanted static or feedback. Once you've paired and connected your phone to the Bluetooth FM transmitter you can turn and hold the Multifunction knob/button on the face of the transmitter to the right. This will ensure the transmitter's volume is turned up all the way. The loudest volume setting on the transmitter is 30 and you should see "V30" on the display of the transmitter. Perhaps we can offer some troubleshooting assistance or provide you with a warranty replacement, if necessary. The following product is backed by Scosche’s 3 Year Limited Warranty and Scosche's Lifetime Tech Support. If you need additional assistance please email our Customer Service Team at customerservice@scosche.com with a link to this review, message us via our chat service or give us a call at 800 363 4490 x1, and we will arrange a swift resolution to your experience.
