Scosche BTTRFM-SP1 Portable Bluetooth Transmitter/Receiver, FM Transmitter and Wireless Audio Receiver for TV, Headphones, Home/Car Stereo, Airplane Entertainment and more, up to 7 Hour Battery Life

Just got it today so I can't comment on the battery life but it is very easy to use and works very well. I love that it doesn't need batteries and comes with charging cord and auxiliary cable.

Bought this to play iPhone podcasts and music thru an old car radio since the radio lacks an Aux port or any other input besides the radio antenna.Couldn’t figure out how to change the FM transmit frequency. Called Schosche customer service, who explained that some steps were missing from the instruction manual on the Amazon web page. They emailed me the missing steps: To change the FM transmit frequency, hold the PLAY/PAUSE button until the FM frequency digits flash. Press the Track Forward or Track Back buttons to increment/decrement the FM frequency and match it to the (otherwise unused) FM frequency on your radio receiver. Press PLAY/PAUSE again to lock in the frequency.Had trouble pairing via Bluetooth. Schosche customer service suggested updating the phone to the latest iOS version. That worked.Audio clarity is fine for car audio. A self-adhesive Velcro strip (not included) holds it in place. Recommended.

What a great sounding tiny radio! General coverage shortwave too! I need to run some more tests on it but so far, I had decent selectivity. You will need an external wire for shortwave though but I did receive some strong signals. Not the easiest controls to figure out but you will get used to them. I am not sure on how long the charge lasts on the battery as of yet. The sound through the included earbuds is very good too. Good value and a great value on sale.

Only used for a short time until car traded but worked very well.

Aug 28, 2023: The device worked yesterday for a little while but I started hearing blips and the sound cutting out momentarily. Then the device suddenly stopped playing music altogether. I tried numerous times to turn it off, on, off on and pair. Nothing worked. The little blue light blinked but nothing else. No music. I'm not happy. It was great while it lasted but it's useless now unless someone has a solution.July 12, 2023: Set up for this device was easy-peasy. It's a very small device so doesn't stand out or get in the way of anything. When I replaced my iPhone 6 with the iPhone SE, the SE did not have a port for headphones or an AUX cable. Now with Bluetooth and this device I can listen to my Amazon Music tunes in the car, through my car dashboard speakers. How great is that! I love it. Now I bought the car adapter for charging the device.

I use this with my pipboy 3000 mk V

It's a great idea, but not exactly the best execution. Bluetooth range is fine, whatever, but what it needs is fm range. I'm carrying a handheld radio and it's static depending on if I hold it close to my chest or at arm's length while the transmitter is in my hip pocket. And I still have to hold onto the antenna to use my body for reception.

This transmitter was easy enough to connect and it does perform it's core function of relaying Bluetooth audio to FM radio.Sound quality is sub-par for any audiophile, but I was able to get the volume loud enough to hear over normal road noise.It is very portable, but this is not an ideal solution.The signal strength is VERY weak. Anything more than about 6ft from the antenna results in nearly no reception from the unit at all. While this may be standard, or perhaps even FDC restricted, it is quite inconvenient as my antenna is located along the rear car window.This may be cheap-ish... not sure that equals value here. I'll use it, but with a name like Scosche, I'm not sure there is much better available. The quality of the unit is fine, the quality of the audio is "meh", at best. Consider me content with this purchase, but not happy. I would definitely choose a new stereo head unit over this if I didn't care about keeping factory equipment in my car.
