Cygnett GrooveTrip II
Price: £19.99, Type: FM transmitter, Connection: 3.5mm cable
There’s nowhere to store the cable on this FM transmitter, but it was simple to use and had a bright backlight. The Cygnett comes with only four presets and there’s no auto tune. While it’s easy to change channel manually, it couldn’t broadcast on 87.9FM – our favoured frequency because it’s often empty. The 3.5mm cable is a bit short, at 5cm, but the GrooveTrip II isn’t bad for £20.
