RetekessPR13 Portable FM Receiver, Mini FM Radio DSP with 24 Hour Clock for Drive-in Church, Teaching, Simultaneous Translation, Meeting, Tour Guide, Correctional Center(Pack of 10)

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.

I just received the 10 pack. The radio is very sensitive, the audio is great.Some things to know.Time setTo set the time, instruction book is wrongNote: the clock is 24 hour mode only.Turn off ReceiverPush 4+5 keys at the same timeHour blinksUse the Tune Up or Down to set the HourPush 4+5 keys at the same timeMinutes blinksUse the Tune Up or Down to set minutesPush 4+5 keys at the same time to set clockNote:The 5+6 keys at the same time also work like the 4+5 keysdescribed aboveTo store an FM FREQUENCY station in memoryTurn on radioTune by holding Tune+ or Tune-It starts Scanning and will stop at a signalTo program the displayed frequencyPush MEM then select a memory location: 1 to 5Do this for each of the five memory locationsTo overwrite a memory location select the FrequencyThen MEM then a memory locationThe Earphones provided are very poorBut the radio audio output itself is very clearDo 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 MonoPress and hold LOCK to lockout other buttonsOr to cancel the button lockout featureI use these with the 1 watt transmitter hooked to TV audio out. Dialog is crystal clear, better than captionsRecommend !!

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.

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.

Bought ten radios, only five worked. Bought another pack of 10 - only two worked. Avoid this junk.

I am impressed with the clear sound quality. It's easy to use as well

Thanks

Easy to use and to explain to users. Light weight. The ability to select and fix a frequency on the receivers (and have the frequency remembered the next time it turns on) is a plus for my application. Much better than the (admittedly old) units that scanned to find the frequency, then lost the lock periodically.One of the 20 units I ordered failed in the first 2 weeks of use. (The frequency on the display was off from the frequency it was actually receiving by 0.3 MHz.) Got a replacement with zero hassle and no challenges. I have great confidence that they did test the unit before it shipped (because the problem showed up on the third or fourth use, not the first). My measure of good customer service is not whether problems occur (nothing is perfect) but how well problems get solved, and this was a good experience.
