Before I got the JBL Synchros S200, I got the JBL J33. Basically this was the previous model before the Synchros S200 was released. Take a look at this video where I review the JBL J33. I still have it and it sounds incredible! I currently use these as a backup in case my JBL Synchros S200 break, which has happened once already.
This In-Ear headphone is not Bluetooth, but you can use it with the Avantree Clipper Pro to convert them into Bluetooth.
