Retekess PR13 Portable Receiver Mini FM Radio DSP for Tour Guide System Tour Guiding Teaching Travel Simultaneous Translation Meeting Museum Visiting(10 Pack)

These function very well as listening devices for people in our church. Sound is good and they connect well to our FM transmitter in the room. Here's what I don't like: The LOCK function locks all controls including the volume. Elderly users are confused by all the buttons so we keep them locked but it would be good if they could adjust the volume. There's a clock on continuously that is useless. All this does is drain the battery. Price is good and performance is good but we just have to keep an eye on the batteries.

Muy buenos

These FM receivers are very lightweight and easy to program. The only reason I didn't give this unit 5 stars was because of the ear buds that came with each unit. The ear buds are adequate, but a 5 dollar pair of headphones improves the sound 3X. So for our church members that need a receiver, they all loved the receiver and the headsets because they could remove their hearing aids and enjoy a normal service. Aside from happy elderly, great sound and stereo seperation, plus much more bass with a head set.

I just received the 10 pack. The radio is very sensitive, the audio is great. Some things to know. Time set To set the time, instruction book is wrong Note: the clock is 24 hour mode only. Turn off Receiver Push 4+5 keys at the same time Hour blinks Use the Tune Up or Down to set the Hour Push 4+5 keys at the same time Minutes blinks Use the Tune Up or Down to set minutes Push 4+5 keys at the same time to set clock Note: The 5+6 keys at the same time also work like the 4+5 keys described above To store an FM FREQUENCY station in memory Turn on radio Tune by holding Tune+ or Tune- It starts Scanning and will stop at a signal To program the displayed frequency Push MEM then select a memory location: 1 to 5 Do this for each of the five memory locations To overwrite a memory location select the Frequency Then MEM then a memory location The Earphones provided are very poor But the radio audio output itself is very clear Do not judge the quality of the radio by the audio from the ear buds provided. Solution: Use a higher quality ear bud. The S/M button switches from Stereo to Mono Press and hold LOCK to lockout other buttons Or to cancel the button lockout feature I use these with the 1 watt transmitter hooked to TV audio out. Dialog is crystal clear, better than captions Recommend !!

Update: The seller sent us a new system that works great. This seller has excellent customer service and we are very happy with the product we have. I bought these 10 receivers along with the TIVDIO T-300 0.3W Portable Stereo FM Transmitter. We bought this to translate between two languages in our church. We tried it for two Sundays and then had to return the hardware. The sound kept going in and out on every receiver and there was low level static on and off with each receiver. The earbuds provided were not very good. The volume was low and the sound often only worked on one side unless you wiggled the wire. We solved this by switching out the earbuds for a better quality one, but the static and fading in and out were still an issue. Maybe with a more powerful transmitter this system would of worked, but I don't know enough about all the legal issues to buy a more powerful transmitter, so we decided to go with another company that offers a complete package, which of course costs more. I give this review three stars because this was close to working and the seller has excellent customer service. They worked with us and tried to get the system working for us and when we decided to return it they refunded us all our money and paid for the return shipping.
