## Description

Bluetooth car adapter for hands-free calls, music streaming, and customizable settings on large display with powerful microphone for clear voice quality.

Review: Great device - Had a few of these type of devices over the years and they have all been a bit of a let down. Thought I would give this one a go due to the good reviews and wow, what a difference. I have been using it now for over a month and it has worked flawlessly the entire time. No issues with bt connection but the main positive for me is that I have had no problems with interference and the sound quality for streaming music has been excellent. Then you get the bonus of the nice screen with some info on what's playing and a equaliser. Hands free wise, it always works great and I can be heard clearly by callers. I really am very pleased with this device, worth every penny and saved me having to upgrade the head unit on my car.

*by I***B on 8 May 2023*

Before purchasing the Nulaxy, I bought and returned two other offerings from Amazon that proved to be poor quality. However, not so with this one. This device actually exposed the poor quality of the UK analogue FM transmitters, because what it sends to my car radio is actually a massive improvement in clarity. It has such excellent fidelity and stereo separation that music tracks from a flash drive fill the interior of the car. It's also clear and sharp enough for audio-books and language learning. To minimize static noise, the volume on the Nulaxy should be turned up full, and thereafter, the loudness controlled by the radio. In my case, I found signal to noise ratio was best at the 88.3 MHz end of the FM band. Oddly enough, I initially experienced a little static at that frequency, but it eventually faded away after a day or two. As for the telephone hands free facility, I have been told that my voice can be heard clearly. If you have a deeply recessed car socket, as is the case with my British Ford Focus, you will find that the Nulaxy won't reach. However, I overcame this issue by using a hard plastic two-way adapter (https://www.amazon.co.uk/Double-Socket-Cigarette-Lighter-Adapter/dp/B003VP1M5I), which is also now available on Amazon. If I had to make one criticism of this product, it would be that the volume control is pointless because, as I mentioned earlier, to achieve best quality reception with lowest noise it needs to be permanently turned up to maximum. It would therefore be a big improvement to redesign the unit so that the volume control is replaced by a fast-forward and reverse facility for audio playback. Such a design modification would be particularly useful when listening to audio-books and foreign language education files. The best that the current design can do is jump forward and back between files, rather than moving within them. Loudness level could then be included in the settings. *UPDATE*: I'm reducing this from 5 stars to 4 stars because it completely destroys radio reception very near the chosen transmission frequency of the Nulaxy, and causes signal reduction of any stations broadcasting at around 10MHz higher or lower than the chosen frequency on the Nulaxy. Unplugging it would correct this situation, but then by doing that you lose the phone hands-free facility.
