@ParachuteBoy - We got the JBL Charge for our D - it is a great little speaker - it worked so well for her for auditions - we got one for our older D who was teaching a tap class (through a college club) and the volume was great in a big room of people all tapping! My girls loved theirs so much - I bought myself one! It’s amazing how much sound the little speaker can put out! My husband did a ton of research before selecting this model for it’s balance of features and price! You can either connect to the speaker with a cord - or with bluetooth - and you can be across the room from the speaker for bluetooth. If you use your phone - be sure to switch to airplane mode before your audition so no texts or notifications come through while your song is playing!
