I have the older version of this which is great for practising quietly as you are going through headphones. My phone is an iPhone 7 which Apple kindly removed the headphone socket from but this version uses a lightning connector, so once I save my pennies I will get the updated version. I find my practising curtailed by having people constantly in the house, especially at this time.
