Cubetek Bluetooth V4.1 Audio Receiver, Wireless 3.5mm Adapter with MIC, for Home Audio, Earphones, Car Stereo, Connect 2 Devices at Once, Model: CB-BTI-028

Sound quality is amazing (better than other BT devices I've tested)Battery life is as good as it can get for a device this size.Comes with all essential accessories to charge and use it with multiple device types and the build is good quality matte finish plastic with clean and precise cutouts (unlike other brands within this price range)The bluetooth humming noise too is barely noticeable and completely drowns out once you start playing any audio.

Initial impressions only. Good product. Using only in car till now and the sound quality is very good. U can pick up and disconnect calls without touching your phone. Reception of mic is also good. Might update to 5 stars later, after using for a few more day if I find a good battery back-up.

This device is an excellent product. And excellent battery back up. Don’t waste your time in searching other products. It will connect automatically when switched on at it also shows battery %in our phone.actually I’m using this in my helmet and it doesn’t create any disturbance in sound clarity and mic is also working good with good sound clarity

Product is good but packing was opened

Pros-1.Good quality sound due to CSR chipset.2.Battery backup is good. Getting 7-8hrs of usage on1.5hrs of charge.3. Works even while charging but dont do it often.4.Connects mostly on 1st try or automatically.5.Check battery level on mobile near Bluetooth icon if your android version supports.6.Call quality is good.Cons-None as of now. Does what is meant to do.

Sound quality could have more better. I am also using mpow, this has much better sound quality. Mic is good and people can hear you clearly. The basic functionality is missing like , when device is connected to phone there is no notification sound. Also, when I pick the call, the notification sound is missing.After using it for almost 2 months, I would say just go for it. I tried many devices but, it has everything you want like sound quality, battery backup and most important call quality. One suggestion, please add notification sounds (when connects to phone or when call received) a bit louder.I am charging this device in a slightly different way, using solar panel. And there I found one issue, while charging the device and when it goes from bright sun light to low sun light, Bluetooth gets disconnected. I am not using any interface between device and solar (5 volt)panel. If you guys can solve this problem, it would be great.

After searching so many products and going through their reviews, I finally bought this. From the last 3 days I am using it in my car. Connectivity is very good. On phone, once it's connected through Bluetooth, it shows the battery level of the device, which is a cutting edge feature. As the battery level is low, just charge at that time, instead of plugging all the day. Overall I am happy with this product.

Ease of connectivity, one full recharge can give 2-3 days usage on regular long use, and yes, sound clarity is one huge plus point, been parmanently using it to hook up my phone n laptop to my sound system for the last 1 year or so.
