Accurate reviews for a good product
I read a lot of reviews before purchasing this and I'm happy to write that the positive reviews were accurate.<br /><br />I accidently ordered the 580A instead of the 980A, but decided not to return after reading that the low speed on the 980A was not very useful and few ever used it.  The 580A gives off a mixed sound of static and fan sound and does an excellent job of blocking and minimizing the noise from the TV when my partner is in her office.  I'm only about 20 feet away from her and with the door closed I can crank the TV up to over 17 on the volume meter.  Way louder than I usually turn it up (12 or 13 is normal for me).<br /><br />The only things it doesn't block well are distinctive noises, like talking on the phone, although I do have a rather loud and projecting voice.<br /><br />I would definitely recommend this and will probably buy another one for the bedroom when one of us goes to bed while the TV is still on.
