I bought these about a week ago from Harvey Norman in Narre Warren a suburb of Melbourne, Australia. They have an excellent sound. As a reference I have a set of Quietcomfort Bose 35 II and these JAM are replacing my faulty Series 1 AirPods. Got them at $40 off, so for near 1/2 price. They are comparable in audio quality and ridiculously better value. I needed them to not have Noise Cancelling (for which I have the Bose and BTW I also have a set of Noise Cancelling Headphones from Aldi which about 75% as good as the Bose but much cheaper - mentioned only to indicate I have a decent selection of audio gear to compare these JAMs to. They are super comfortable all day AKA 6 to 8 hours (I find I need to move the Bose around a bit after 2 to 3 hours). Battery life is best in any class and with the charging case unbeatable. So secure. Nice they stay connected even when taken out of my ears. Very handy, whilst I understand less secure buds are best to have the facility to turn off when they fall out as a warning. Connecting is so easy and consistent (tip: only pair one bud to your device and always connect the same one. The second one connects to the first bud. I always connect the left one to my iPhone X. I can’t fault these and am so happy with them. You can’t go wrong. The case is USB type C so the best you can get. Nice solid case. Charge level shown on outside case and also has the level indicated on the IPhone. The documentation was faultless. I have never experienced such complete and thorough documention ever. You can also download digital editions if you prefer that. Thank you. Warrick.
