I used to use Philips H9505 ANC headphones in the office. Loved them but headband broke and I couldn't find replacement for a long time... I'm very picky about sound quality so numerous popular Sony, Bose, JBL ANC headphones just didn't sound good to me especially for the price... Finally totally accidentally I bumped into the Audio-Technica ATH-GL3 review and decided to give them a try. Love them so far:Pros:- Great sound - clean and airy - great for all kinds of music. IMO these sound better than most ANC headphones which are 3 times more expensive...- Good ergonomics - headset is very light and fits perfectly on my (large) head.- Closed design - isolates well in the office environment, once I turn on the music I cannot hear anything else. Doesn't leak sound.- Microphone doesn't pick other conversations going on in the same office (...I have some very loud coworkers...)- Two cables included - long one with 2 connectors and a short one with single connector. Cables have flat surface (not braided) so they don't produce a sound when touching clothing/table.- Wired - don't need to charge anything/anytime, reliable connection.Cons:- Microphone is not foldable into the headset (to hide it when you don't need it)- Connector on the headphones looks wider than standard 3.5mm - not sure how easy to find replacementNotes:- The headphones have high sensitivity/low impedance so they don't require a headphone amp - you can plug them directly into PC/Notebook using the supplied cables and they sound loud and great...- I actually ended up buying a small/cheap headphone DAC/amp (Fosi) and plugging the headset into it. The amp has analog Bass/Treble tone control knobs which allows me to tune sound quality to my taste for different records. And yep those simple analog tone control blocks are IMO by far better than any software equalizers... Total cost of the headset with the amp is still about 1.5-2 times less than most popular Sony/Bose headphones and the sound is better.
