Love this

Love it - only reason not 5 stars is because it requires some tech savvy skills and I struggle!

Love my h2o

The sound is strong and much better than I ever experienced with other waterproof mp3 players. I can really listen to audio books and not loose a word even when the sea got waves, that's a first ! So I'm very happy with my sonar pro and surely recommend it to all swimmers around the world!

Pairing difficulties

I have an iPhone 11 . I am unable to pair it with the sonar pro. I is completely charged, my phone is in Bluetooth mode . I have other devices paired ( ear pods and a speaker) but I cannot pair sonar pro. I have tried to pair it with my laptop which tuns on windows 10 , unable to pair it to my laptop.
