I use and have used my Bose (QC-1 and QC-2) for years on rechargeable AAA batteries. (The QC-3 comes with an internal rechargeable battery.) Work great and most of the time can get an entire contest in on one battery/charge. I keep some spares with me. I can always buy a primary cell if I am caught somewhere without a charged battery, which hasn't happened yet in years of use. Using AC mains is the worst. It could introduce ground loops, hum, tether you to a power source, extra wire tangle, etc. >73, >Erik K7TV > >----- Original Message ----- >From: "Ken Alexander" <[email protected]> >To: "Elecraft_List" <[email protected]>; "dw" <[email protected]> >Sent: Thursday, March 19, 2009 1:08 PM >Subject: Re: [Elecraft] Bose noise canceling headphones > > > > > > I have a pair of Sony noise-canceling headphones that I'm really pleased > > with.
