Great sound quality with simple application
Have an older car that isnโt equipped with all of the new fancy technology. I ordered this Avantree CK11 and it is working for my needs perfectly. Once I charged it and paired it to my phone, I had immediate connectivity. The volume is nice and loud easy to hear and the calls have great quality to understand. It pairs well with my iPhone and Siri. I can even have Siri read my text that I can hear over the speaker and reply if necessary to my text without touching the phone. When necessary I charge it overnight and itโs ready the next morning. I charged it in January. Itโs now April and it is still fully charged.It connects to my phone as soon as I open the door and get into my driver seat. Itโs a handy little device for hands-free cell phone while driving. Connecting and disconnecting with calls is one button function. Iโm very satisfied with my purchase. I wish I had done this sooner.

Easy to Set Up and Works
Live in a handsfree state and needed a hands free device to or faced possible fines for talking on phone in my older car. I tried a cheap device which sort of worked but no one could understand me nor could I understand them. This synched with my phone on the first call and connects with the phone every time I get in the car. People can understand what I am saying with minimal road noise and without it sounding like I am in an echo chamber. They say I don't sound quite like me when I'm on my phone, but I don't care as long as they can understand me. FYI for those new to using the phone, you can turn the sound dial more than one time around to increase volume. First time using it I thought it only turned once and the sound was too soft to hear. I kept turning until and discovered it still got louder beyond 360 degrees. Very easy to adjust volume while driving, turn off or disconnect call. Only reason I'm giving it a 4 is because cord is a little too short for my car. I can't clamp it to the dash like the directions illustrate because the dash ridge is too big. If I attach it to the sun visor it dangled dangerously around the steering wheel. Finally figured out a way to attach to right side of visor, drape power cord over the back of the rearview mirror support and down the right side to the power socket in the front dash panel. When I want to change the position of the visor, I have to move the device because there is not enough slack in the cord which is a pain. Another very minor complaint is that I can't distinguish what the device says when I turn it on and off. Voice for Power On is indistinguishable for Power Off to my ear. Other than a way to attach it better to all dash panels, I am extremely pleased with device.

Great speaker
Picked one of these up in Dec for a 91 Corvette. I've tried several different types of these, and I feel like this probably the best you'll find for this type of bt speaker. The battery life is outstanding. It's on all the time, and as of today, it's down to 80%. The others I've tried, I was charging them every week or 2. It's plenty loud to hear people clearly while I'm driving. The mic picks up my end clearly as well. I've had no complaints or constant "what did you say?". I can actually hold a conversation. The only thing I can knock it for, is the nose cancelling. It's not the best in my car, but my car is rough riding and not quiet over expansion joints and the like. Other than that, I'm very satisfied with it.

Best I've tried so far
I've tried several devices. Once I figured out its quirks, it works pretty good. I wish it had a visual indication to let you know that it is connected. Based on the ones I've tried so far, I would buy this again but it isn't ideal. If the power source connected directly to the car and turn off when the car is off, it would be really good. My only real issues are: It may not connect when I get in the car, I have to connect it manually. It may not disconnect when I get out of the car (This is the worst since I rely on my phone for my business) and it stays connected in the house. I have to disconnect manually. While it does work, I will keep looking.

Easy to set-up, automatically reconnects, loud enough to hear
The Avantree CK11 is an excellent way to enable hands-free interaction with your cell phone in an older car that doesn't have Bluetooth built-in. Just press one button to pair the phone with the CK11 and you're done. The unit turns off a few minutes after you leave the car. It turns back on and instantly reconnects to the phone when you get back in. I've been using it a couple of weeks and I haven't had to recharge it yet. While driving, just press the button and Google Assistant pops up on the phone waiting for voice commands to call contacts, send texts, open applications like Google Maps or Waze, etc. You never have to take your eyes off the road. Best of all, the unit clips to the car's visor and there is a large volume knob that can crank up the speaker sufficiently to hear calls regardless of the amount of road noise. People say they can hear me clearly when I call, and I can hear them. Bottom line: the Avantree CK11 does everything I need it to do with a minimum of effort.

They've changed to type C!
The blue is the old device, which I've had for a little over 5 years now. The black one is the new device. These are awesome, especially since I have a very base car that has little to no creature comforts. The radio has a mic, but it just picks up the road noise. You can see they're identical, apart from 1 great thing....They changed them to USB C! I was willing to deal with the micro USB since the product has been amazing for so long. The only reason I'm replacing it it because the battery swole up and doesn't hold charge anymore. But after 5 years. The batch number shows how long I've had it. 21D1 (old), 25D1 (new). I'm assuming the 21 is for the year 2021, and the 25 is left over from last years batch. You can't go wrong with it.

Save your money ...
I call this product Garbage, but I don't want to offend the Band, or my household refuse. It does what it says. It connects to your phone via Bluetooth, and it is a speaker. Unfortunately, a speaker with sound quality that will remind you of a Fast Food Drive-thru in the 80's.

Great product for the price and excellent customer service
We bought two of these units for our older cars whose bluetooth software was too old to pair to our newer phones. Setup was easy on the first product, and the sound quality is very good for this price product. In fact, the sound quality is better than my (supposedly preimium) car speakers as far as spoken word is concered. We had issues with the second unit, and I emailed customer support on July 3rd. I didn't expect to hear back from them because of the upcoming holiday but got a response within a couple of hours. I had some dialogue with them which continued on the 4th, and the customer service rep Sara offered to set up a phone conference. In the meantime, I did get the unit to work properly. I switch back and forth from listening to books on my phone and making and receiving calls, and everything works very well. One really nice thing about this unit is you can set it to power on when it detects motion, and it will automatically power off after 70 minutes with no activity. It takes a little getting used to in order to properly interact between phone (I have an iphone) and unit, but it is sweet in the end!

This works really well and was straight forward and easy to connect to phone. Bearing in mind that it's not a Bang & Olufsen system, the sound is good during a conversation even when driving on a noisy road surface, and the person you're talking to can hear you clearly. Maybe you could spend more money on something ' fancier' but I honestly can't see why you'd need to.

Finally a winner!
I consider myself an expert on Bluetooth visor speakers. Iโve owned 4 over the years. I decided not to cheap out thus time and went for one over 50 bucks. Let me begin by saying that you get what you pay for. Pros: - Excellent battery life. I last charged this unit over two weeks ago and itโs still showing 90% - Great sound for 2 watts. No complaints. - easy to operate. I send voice texts with this unit and have no problems. Very easy and seamless pairing. Bluetooth pairing with 2 phones is also seamless and I have not experienced my phones dropping out of Bluetooth like I have with others. Peace of mind. Fast pairing as well. No waiting and voice prompt notifies you when phones are paired. All in all an excellent speaker. Cons: The clip could fit tighter on the visor. The placement of clip on one side of the speaker allows the other side of the unit to dip down on bumpy roads. I think the placement of clip is to allow you to replace lithium battery after theyโve run their life out. Would have been better to affix the clip to the battery door. - Pairing light is very dim. Canโt see it during the day too well. That being said... I am a night driver and itโs nice that the light is not flashing brightly which can be distracting. M nit picking. Thatโs it!! I would definitely suggest this speaker unit to friends and family.
