Review: Recommend - 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. Review: Does the job - I've been using this unit now for around 6 weeks. The battery lasted around 5 weeks from a full charge, connected to 2 phones simultaneously for around an average of 6-7 hours per week (with satnav directions running through it) and an average of 30 mins to 1 hour phone calls per week. Not bad going really and better than I had expected. The auto on/off works very well too. Only slight negative is it plays a low battery message when it runs down to 10% battery, which although a good idea it does get a bit annoying that it repeats itself every few minutes. Sounds quality is more than adequate, slightly 'tinny' sometimes when at a louder volume but most of the time perfectly fine. If your car has a fairly quiet drive or you mostly spend time driving at 50mph or less you'll be fine. It's only slightly tinny sounding when I have it turned up loud and that's only needed when I'm driving at 60mph+ and because my car isn't very sound proof! 99% of the time the person on the other end can hear me clearly and the 1% times they can't it's usually poor signal on my mobile which is no fault of the unit. I debated whether to get a Bluetooth unit that played through the car stereo but glad I didn't. I listen to music through the stereo and this unit plays my phone satnav directions. Overall I'm happy with the purchase; does the job well and at a decent price point. ## Features - 【CONVERSE CLEARLY】With our built-in 3W speakers, echo & background noise-reduction feature, and volume controls- your calls will be crystal clear no matter where you are! - 【DISTRACTION FREE DRIVING】Encourages safe driving by using Siri Assistant to make phone calls, send texts or get driving directions. - 【DRIVE WITHOUT DELAY】Our motion sensor enabled CK11 allows you to turn your device to ‘Auto Power On’ so the device turns itself on when your car door opens and off when the Bluetooth disconnects. - 【LONG BATTERY LIFE】Get lost in your calls, music or driving directions with up to 18 hours of battery life!

I am frustrated as I did at one point manage to make the unit play spotify and audible. but only a short while late I couldn't get it to do exactly the same function. I cannot work out why but it does not seem to respond to the "Hey google" voice request any more. Why? Can I make it work? Should I return the unit because it doesn't fulfil its initial promise? **Q: does it tell you who is ringing?** A: No, this unit will ring when a call comes in and will not tell who is calling. **Q: i need a longer lead , can you recommend one ?** A: The lead comes with the product is the common USB cable, if you would like a longer one, it can be found easily at any electronic shop. **Q: Does it work with a none smart phone ie doro** A: Sorry I couldn't say as mine is a smart phone and it works great sorry I was unable to help ## Customer Reviews ### ⭐⭐⭐⭐⭐ Recommend *by A***L on 10 June 2026* This works really well and was straight forward and easy to connect to phone.

I have given this item a 4 star because of its design to sit ontop of your visor, but when I do that the visor won't go up, so I located the clip at the bottom but with vibration it falls off, so I've had to improvise using a strip of rubber for packing, so far so good. A clip on the side would be better. ## Frequently Bought Together - Avantree CK11 Hands Free Bluetooth 5.0 Car Kits, 3W Loud Speakerphone, Support Siri Assistant & Motion Auto On Off, Volume Knob, Wireless in Car Handsfree Speaker with Visor Clip - Titannium - Avantree Roadtrip - Car Bluetooth Speaker & Wireless FM Transmitter Kit 2-in-1 for Streaming Cell Phone Audio to Car Speaker with Hands-Free 6W Speakers, Built-in Mic, and Long 22hr Playtime - Miracase 3-in-1 Cell Phone Holders for Your Car, Universal Car Phone Holder Mount for Car Dashboard Air Vent Windshield Compatible with iPhone 16 15 14 13 12 11 Pro Max Xs XR X, Galaxy Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.br/products/58295341-avantree-ck11-hands-free-bluetooth-5-0-car-kits-quality](https://www.desertcart.com.br/products/58295341-avantree-ck11-hands-free-bluetooth-5-0-car-kits-quality) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-07-13*
