You’ll enjoy full, beaming sounds thanks to the 30mm in size drive units that provide a very very insane sounding deep bass with no distortion and a wider dynamic range for static free listening. For the ultimate comfort, these Sony noise canceling headphones feature a wide headband and soft headphones that fit so snugly around my head and everyone I asked said they felt too comfortable almost lol. While your at it, you should know and take advantage of the other great features such as the easy position mute function, single finger volume control and auto power in-case you forget to turn the wireless stereo headset off or if your just too lazy to hit a button.

You get easy plug and play setup, a nice looking form factor and very user friendly customization options at a surprisingly fair price. Just like my Sony wireless notebook mouse, having the 2.4GHz signal lets the bluetooth stereo headphones be used in any direction and angle within a 30ft area. Technically they can pick up a signal from 100 feet away, but most places you go will have walls or appliances. Which like all bluetooth digital handsets can slowly degrade that 100ft range.

With that said, these Sony MDR-DS6000 2.4GHz wireless digital surround RF headphones can easily for me receive a 5.1 digital signal through three standard walls and up a flight of stairs before showing any signs of static and the only time they have trouble maintaining a digital signal is when the source itself fails to send a signal for five minutes and the stereo handset can lose signal. Re-syncing though is simply a matter of pressing the a button on the units but be warned that it can take a few presses and up to a minute for the signal to come back and the unit to turn back on. It really shouldn’t cause a problem for anyone unless you are a gadget lover and must have total perfection! (I always feel with any product that you get what you pay for).

The Sony 2.4GHz wireless 5.1 digital headphones work by a rechargeable battery pack in one earpiece that can be recharged simply by placing the MDR-DS6000 set on the base – sounds easy enough. The base you have to plug in with the included but very small AC adapter and then connect to any digital audio source… and just like that, you’re up and running.

When the batteries die down, simply place the bluetooth device back on the base for two hours and you’re up and running again (or if it’s an emergency, you can just insert two standard AA batteries which Sony gets a big thumbs up on). An amazing audio tool for those who can’t afford a full blown surround sound setup or just if you need to listen at a high volume during quiet times like your room in the middle of the night.

I was also really impressed and shocked with the range I get in the gym, home, car – basically the Sony DRBT50 bluetooth stereo headphones had no problem regardless of what I was doing. If you have tried other bluetooth stereo headphones and they didn’t meet your needs, these Sony bluetooth headphones are top of the line quality and built to list. In my opinion, I can say these are the best you will get for the price and I definitely recommend it to everyone.
