Question: Does the ear piece come with a microphone to talk into?
Document: We have had these for over a month now and they work well. We bought them for keeping in touch on the property and at the ball fields etc. They are kid friendly. The battery life is a whole day at least of continuous use and 2 days with light use. They talk to you and tell you which channel it is on and when the power is low. You can use the ear pieces... or not.
We ordered 10 walkie talkies for our staff. We operate a large testing lab, where we need to stay in touch. The ear piece is a little uncomfortable, but better than I expected. The sound quality is good and the units appear to be well made. I expect we will receive years of serviced from these walkie talkies.
I've been using these radios for almost a month now in a ministry setting. I ordered 10 to start, just ordered 5 more. I love them! Great build quality and easy to use. I wanted something that was hard to mess up, dials for power and channels help achieve that simplicity. The ear sets that come with the radios aren't great, I ordered different ones, found one stopped working well the first time I used it. Over they are a fantastic radio and the price is great!
We purchased the radios to keep in communication when setting up and orchestrating a fireworks show. The radios were great, we were able to speak with each other and hear each other regardless of the noise around us. While the MC was speaking I unplugged my headset and turned up the volume and everyone around me was able to hear the speaker through the radio. We had the speaker keep the mic open on the radio so the crew in the back could hear. The ear pieces work great.
I purchased these a few weeks back for our church worship/media and ministry teams. I purchased 10 total and ordered the clear earpieces produced by the same company. The earpieces that come with them aren't worth it. That's why this is a 4 star review. But other than that, no problems, yet. I've been a bit skeptical about these but we'll just see. They work well. Started using them right out of the box. I think these are perfect for single building institutions/businesses.
professional quality: loving it
You cannot beat this deal. Purchased for supervisors in a bakery setting with concrete walls. A little skeptical at first but after we implemented them, the result was phenomenal. So much that we purchased another set of 5. Great product!
We've had other walkie talkies in the past, all supposedly with great range, but this is the first one that delivers on that promise. I bought them for road trips. I have my in-laws visiting from Germany and they would not be able to call me using their cell phone when we are in two different cars driving somewhere. I don't want them to get lost and so the idea of buying walkie talkies with good range came to me. I tested the range recently and was really impressed.
We use the radios 7 days a week and Will need more time to see its performance. A little to early to tell.
These walkie talkies are perfect for our application. Very easy to use. Durability seems more than satisfactory. Would purchase again.
Answer: The microphone is not the best quality, several of ours stopped working after just a few days. But the earpieces and the radios were still well worth the purchase.
