This is a bit like 'What's the best coffee?'. Everyone has their preferences, usually discovered by trial and error - not to mention expense. I tried the Ancol/Pure Dog Listeners one and was impressed from day one. Went from small to medium when Jack was big enough. Very well made and holding up well after 18 months, just needs the occasional wash when it gets a bit grubby. There is a learning curve to figure out the best way to put on/take off (there is more than one way) but then super-easy. Takes less than 5 seconds - in total. Oh, and it works!
