Summary: How to waste $100.00
Review: I purchased the phone in the hope I had found a wonderful product w/some of the features I had wanted. It's just not it and am contemplating returning it...but I am not sure for what. I loved the size and weight of it BUT that's it! A lot of money for very little.

Summary: NOT really headset compatible
Review: I specifically purchased the AT&T 9520 to use with a headset. I even bought the "recommended" (by Amazon.com) AT&T headset. When I received the phone, I discovered that there was inadequate headset microphone amplification resulting in callers not being able to hear me speaking. And this is NOT a headset problem. I tried several different headsets (Jabra, Plantronics, Radio Shack) and they all had the same problem. All of these headsets worked fine with a Northwestern Bell 39512 2-line 900MHz phone that I bought AFTER I gave up on the AT&T 9520. The only good point to this phone is the phenomenal range, but this is typical of 900MHz DSS phones. Bottom line - good phone for the money if you're not going to use a headset.

Summary: Not a good buy
Review: The quality of sound is terrible. When I plugged in the headset, it didn't get any better - especially for the other party. There's some kind of an echo. I also bought AT&T H8500 which is almost exactly the same phone and it has the same problems.I like the size. I also like the fact that it charges a spare battery. When power goes out, the spare battery temporarily powers the base so that you don't lose the use of your phone.

Summary: If not for the battery...
Review: Theoretically, this is a great phone. It looks nice, feels good (solid and not too bulky), has reasonable sound quality and range, and a headset jack. As a bonus, it has a compartment with an extra battery in the back of the base, for those long conference calls. Perfect. Unfortunately, it suffers from one fatal flaw - the battery. When we bought the phone, we immediately noticed that the battery life wasn't exactly long; if we didn't always return the handset to the base, it would run out. Now, less than a year later, both batteries die suddenly a few minutes into the first call, no matter how long we leave it on the charger. To make matters worse, the replacement battery doesn't appear to be one of the standard ones available at local stores (which have a wide selection), so we can't replace the batteries; we're forced to buy a new phone. Don't buy this phone; it's unusable. A pity, because in every other respect this is a great product.

Summary: Great phone - if you want to sound like you are talking in a
Review: This is the worse piece of junk I have ever bought, AT&T should be ashamed of themselves!!!!! The battery life is really short, it disconnects the call when you answer but worse than all that I feel like I am talking in a tunnel. I am now searching to replace this phone!

Summary: Hurts my ear
Review: This phone has great range and clarity. It's also very small and light, making it quite portable. However, it doesn't have many features, the volume is low and not adjustable, and the dang thing is so small that someone with stubby fingers would have trouble dialing. Also, it's uncomfortable to use. The phone wasn't right for me and I returned it for the ATT 9400. But it's good at what it's designed for.

Summary: Goes where no conventional cordless has gone before
Review: This phone is my first excursion into the world of 900 MHz telephones. I am quite pleased with this product. It has at least two times the range of my old AT&T 5470 which it replaced. The battery back-up for the base station is a useful feature, especially if you are stuck with an unreliable electric utility company. The handset is noticeably smaller than a conventional cordless and is very portable. A user will find the keypad difficult to use only if he has fingers the size of bananas. I also purchased the AT&T 90800 headset for use with this phone and recommend it as a useful accessory. Overall, this phone has proven to be as advertised.

Summary: Great phone
Review: This telephone has outstanding range and clarity. It's at least double the earlier 900 Mhz phones. Compact and very light, fully recharges in 4 hours and comes with a spare battery. This phone has a 4 step volume adjustment and the button is right on the handset.

Summary: Too small for it's own good
Review: We thought that a small cordless phone would be a great idea. Boy were we wrong. It's like having to talk on your cell-phone at home. The phone is unomfortable to hold for long periods of time and it has that same tin-can like sound-quality that you get from the tiny speakers they put in cell phones. Also, for a products that cost $100 it looks and feels cheap.
