I have the Kirkland Signature 10’s, rechargeable. I hate rechargeables, (see thread on are rechargables reliable). I’m upgrading to the Jabra Enhance Pro20 with battery but I loved the fader ability of the KS 10. It allowed you to choose the balance ( fade) between internal and external sound, IE, listening to a book while mowing the lawn was great!! 90% internal sound from the audio book and 10% sound from the mower.
I’ll miss that with the Jabra. They have a preset adjustment but not user adjustable.
