Question: Does it include earpiece?
Document: Bought these to replace 2 junk radios at work in a retail environment. Perfect for what we need in a small 3 story building. Programming can be tricky but with some copy and paste in CHIRP software, had them up and running in 15 minutes. oh, and if you're using these in a business setting with people or customers around, I highly recommend using an earpiece, they can be loud, and co-workers can be embarrasing
The earpiece is comfortable and makes you look like a secret agent. I used the belt clip for using the earpiece. I can't say how good battery life is yet. Overall, these are the best walkie talkies on Amazon (except for the UV-5Rs). If anyone has any questions, leave a comment below.Update (7/10/14):These work great for kayaking. I can honestly say they work over a mile (without line of sight).
they have reasonable range and good sound quality as well as volume good purchase for price, not to big either good for going places.
the radios came as scheduled. was able to test it and it performs as it should. It works right out of the box. small and lightweight.quality wise it doesnt look cheap. my only concern now is product longevity. I hope it will not break anytime soon.
These units were purchased as Christmas present for my three boys. They have outstanding features and quality compared to other units of higher price. We had an issue charging one of the units but , AlwaysOnLine, resolved the problem quickly via email and sent a replacement battery. I would recommend these to anyone looking for units that have good range and sound quality.
The units can be put on the base for charging or you can just put the batteries on the base. It's easier to leave the batteries installed. The belt clip does not interfere with charging. I didn't even bother with the CD. I installed the cable using software, drivers, and instructions I found on Miklor (a website). I didn't have a problem using Windows 8 (64-bit). The installation was pain-free. I used the Prolific driver from the website.
The ear piece is something just now my one son is getting use to. We haven't had any mechanical issues at all. We've even used at sporting events or family gatherings at parks. But, just had to write a rating and comment because these are really great to have.
The battery life is awesome. They have not run out of battery life so far. They are very loud as well. Talking almost sounds like a phone conversation. If you do use these for boating or something like that, don't get them wet as they are not waterproof. Also, don't leave these on the charger if the charger is unplugged. The power will backflow and the battery will drain. The reason these are the best on Amazon is they have lithium-ion batteries.
Im very satisfied with this purchase. I received three radios, good coverage, life battery OK.It worked once I took out from the box.Good size, hands free.I definitely recommend these Walkie Talkies.
If you don't remove this they will be completely non-functional as no power will reach the unit. The handsets are a good size. They are slightly smaller than commercial units. The belt clips are installed by removing two screws on the back and reinstalling them into the belt clip. Remove the battery when you do this. I only did it on one walkie talkie because it adds considerable bulk to them. I didn't install the wrist straps on any of them (yet). I bought these for kayaking.
Answer: Yes it does.
