AURSINC Bluetooth Motorcycle Helmet Headset, Bluetooth Intercom Interphone System for 4 Riders Talking at The Same Time Waterproof IP65 Talking Range 1500m GPS Hands-Free Stereo Music

These are great. Once paired, the work flawlessly. (Read the reviews that tell you how to pair and practice before you go out as it takes a bit, but was quick once I got the hang of it.)Communication is excellent. Wind noise is non existent. Sound is great. We used them skiing and could hear each other perfectly up to 300 yards away. Up to 500 yards with some distortion. The batteries didn't quit for the over 8 hours we used them each day. Charging took maybe an hour.The package contains everything you need with enough velcro for 4 different helmets. They didn't skimp on anything.Overall I'm confidant in a 5 star rating. They are that good. They cost more, but you get what you pay for. I can't wait to try them while riding ATV's.

Bought these for 4 people to be able to talk to each other. Getting them synced is terrible, even with video. Once you turn them off, its awful to get them synced again. Theres a high pitched whine constantly, like feed back on a microphone. You have to stay about 75 meters apart, or you get static & they all turn off.Once they're synced, they work well, if u stick close. You can communicate ok with 4 people.Batteries last 6-8 hours on a full charge.Absolutely HATE the box they came in (see first picture). You pull the plastic tray out, & everything stored underneath falls out. TERRIBLE! We have 2 other v6 sets that came in a different box (see second picture). They're GREAT!!! TO STORE IN & keep them from breaking if they get bumped or dropped.

Setting up 4x V4 VNetphone(no offense to the manufacturers, but many readers have problems with this)This walkthrough will help you set up four V4 VNetphone for use in tandem. The real trick with doing this is performing the Detailed Walkthrough on clean or reset systems. If you have already attempted setup on your radios, pay attention to Step Zero.## Preparation.*Step 1. CHARGE* your radios. I recommend a smart charging system such as the iClever 24W Dual USB AC Adapter. These chargers are good for far more things than this (smartphones, tablets, etc) and will automatically shut off when they sense that your device is at full charge.*Step 2. LABEL* your radios. If your radios are for something other than motorcycle use, you actually need to know which radios are which, not just for this setup, but for every time you bring the radios up. They need to be labeled in such a way that sweat and rain won’t remove the labels.## Step ZeroIf you are in any way using radios that have already been synced at some other time, if you screw up the directions below and and have to start over again, do yourself a favor and just RESET ALL OF THE RADIOS, because none of this will work if any radio has not been reset.*RESET:* While each radio is ON, hold the A & B buttons simultaneously for about 3 seconds to clear its pairing history.## High-Level WalkthroughYou may reach a point in your life where you have done this so many times that the detailed steps are “old hat”. This is the synopsis of what we’re about to do.*Step 1.* Pair #1 & #2 on Channel A, test comms after(Long-press A on both, Press A on #1, wait for blue, Press A again)*Step 2.* Pair #3 & #4 on Channel A, test comms after(Long-press A on both, Press A on #3, wait for blue, Press A again)*Step 3.* Pair #2 & #3 on Channel B, test comms after(Long-press B on both, Press B on #2, wait for blue, Press B again)*Step 4.* Sync All, test comms afterPress A on #1 & #4*Step 5.* (Optional) Pair on BluetoothHold B on #1 & #4 ~ pair both in smartphone bluetooth settings*Step 6.* (Recommended) Turn them all off*Step 7.* Turn them all on*Step 8.* Press A on #1*Step 9.* Press B on #2, #3*Step 10.* Press A on #4*Step 11.* If you only need 3 radios, you can turn off #4, now.## Detailed Walkthrough### Pair #1 and #2 on Channel A*Step 1.* Long-press A on #1 and #2 until the light flashes blue and red*Step 2.* Press A on #1. Wait for both lights to flash only blue in sync*Step 3.* Press A on #1*Step 4.* Test communication between #1 and #2### Pair #3 and #4 on Channel A*Step 1.* Long-press A on #3 and #4 until the light flashes blue and red*Step 2.* Press A on #3. Wait for both lights to flash only blue in sync*Step 3.* Press A on #3*Step 4.* Test communication between #3 and #4### Pair #2 and #3 on Channel B(You’ll temporarily no longer hear #2 with #1, nor #3 with #4. It’s ok!)*Step 1.* Long-press B on #3 and #3 until the light flashes blue and red*Step 2.* Press B on #2. Wait for both lights to flash only blue in sync*Step 3.* Press B on #2*Step 4.* Test communication between #2 and #3### Sync the Daisy Chain*Step 1.* Press A on #1 and #4*Step 2.* Test communications between #1, #2, #3, #4### (Optional) Pair on Bluetooth with Smartphone*Step 1.* Long-press B on #1 and #4 until the light flashes blue and red*Step 2.* In your smartphone, pair with both V4 connections*Step 3.* Upon success, the light on the radios returns to just blue### Feeling Gutsy?We have noticed that there is more battery drain if you take the radios out and use them immediately following the initial sync. This is likely because the pairing chipsets are still active in some way and draining power. So:*Step 1.* Turn all radios off### The Real TestBringing them all up, in this order, is recommended.*Step 1.* Turn all radios on*Step 2.* Press A on #1*Step 3.* Press B on #2, then #3*Step 4.* Press A on #4*Step 5.* Test comms on all 4*Step 6.* If you only need 3 radios, you can turn off #4, now### You Should be Good To GoIf you’re not, see Step Zero, and try again!

Battery powered vox or PTT radios are more dependable.After a handful of uses battery won't last but under 2 hours.Chinese knockoff crap

We just recieved them and played with them last night. When you turn them on to connect the Bluetooth to reach other, don't plug in the ear jack until you Follow instructions, after blue tooth has found each other then plug in Jack for earpiece. Push the A button one last time after you plug in Jack and it works great. We had it all together, Jack plugged in, followed directions and couldn't make it work. Watched a video on line finally and had done everything right except we plugged in the ear jack to soon. The sound was good in the house. We are using them in our snow mobile helmets. Will report back after we use them.

First of all I love using these for refereeing and playing with them with my granddaughter. I have a set of 4 and marked each one with fingernail polish to number them. I started to change the numbering and tried to take the polish off and the acetone started removing some protective coating they put on the device (to keep it water resistant, I think). Very few others would probably do something like this, but if for any reason you want to clean them off, I’m not sure what you should use other than water, but DONT USE ACETONE!

One needs to be right next to the other person. When our snowmobiles started up, we could barely hear each other. We think they would be better for motorcycle riding, when sitting on the same motorcycle!

The sound quality is very poor, can not hear each other talking when my motorcycle is traveling on the roadway
