New - Open Box
  • An open-box item looks and feels brand new, although may show very minimal signs of use. Open-box products are often unused returns, or demo models from retail locations that just can’t be sold as “brand new” anymore. Some of the products may have never even been powered on, but have merely been removed from their packaging at some point. As a result, these products are heavily discounted even though you can expect them to function as if they were new.

This deal is already so low, it isn’t eligible for additional discounts/coupons.

Okay

Tested this transmitter on a 2007 chevy avalanche and it was some static no matter the FM station. 3D made it sound a little better not much. Also, put this same transmitter on a 2015 dodge and it sounded great no static but the 3d sounded horrible like it was echoing. The hands free call feature is clear. I like the 2 usb ports plus usb c port. Overall it's okay if you don't have an update radio and want BlueTooth.

Good product

This product was so easy to connect and get started with. Connects to my phone eveytime with no issues at all. I received these products for free from the Hey, Bullseye™ sampling program in exchange for my honest review.”

Great Wireless FM transmitter

The Wireless FM Transmitter with 20W USB-C and 3D Surround Sound is a great way of playing music in the car. It is easy to set up and I can transmit my playlist from my phone and charge it at the same time. It also sounds great and lights up.

Great little gadget

Most cars now a days come with some sort of fancy bluetooth connection or carplay feature. This is great for when those are not available in the vehicle/escavator your using! Super easy to use and the sound quality is pretty good too! I wish these were around before i bought my current vehicle.

Works to play music without aux

The Wireless FM Transmitter with 20W USB-C and 3D Surround Sound works well to play music off my phone to the car speakers, since I don’t have an aux outlet. The 3D surround sound is a bit tinny sounding in my car, but in regular mode it works just fine. And I can charge my phone at the same time.

Great product, excellent charger!

Firstly, this is an excellent product! There aren’t many flaws that I could find, and I’ve tried everything I can to my knowledge. I got this product for my car so I could have a fast charger for my phone as well as additional functionality my headunit lacks. My car is a Nissan Leaf, and while it supports Apple CarPlay, it doesn’t work well and sometimes not at all! In addition to the CarPlay flaws, the Bluetooth hands free sounds like garbage! So, I thought I’d try a modern day FM transmitter and it sounds pretty darn good if I do say so myself! I thought phone calls were reasonable, better than my car but still not as good as my Chevy truck that has crystal clear voice calls. The quality of music on this transmitter is about 8/10, I’ve heard better (HD radio and Bluetooth) but it’s not as bad as older radio stations that are really fuzzy, and it is better than my Bluetooth loosing connection every few minutes or so and driving me crazy! So, I can 100% recommend this unit at the least for a very cool charger and the added functionality of the FM transmitter. I will add in closing that one or all photos shows the unit “pinched” against my trim and that’s no fault of this unit, just fault of Nissan putting the 12v outlet in a crappy spot! But be warned if you’re in a similar situation as me and you don’t have much space.
