Summary: For its size and portability, this speaker is a very solid purchase. This speaker is LOUD with very "party-like" bass. It is near ridiculous how loud this thing can get while battery-powered, and it will be sure to impress people.
Summary: If you're looking for a way to take some tunes with you to the park, by the pool, or anywhere that requires a more punch than the typical portable bluetooth speaker form factor provides, there's not much else in the market segment that can touch the A73.
Summary: Good sound quality, issues with Bluetooth connection and battery. The battery does not last very long. Sometimes as short as 45 minutes. The Bluetooth connection randomly drops out on the iphone 5. Having said all that this speaker really has no rivals in terms of sound quality in this space.
Summary: Bought this for my wife for her birthday party. It connected with her cell phone via bluetooth without any problems. It puts out some serious sound. Turns out I liked it more than she did and since it was her birthday; she didn't like it so it had to be returned. I want one for my birthday!!
Summary: This speaker has a great sound but just goes off every ten minutes. It does not matter if the bluetooth device is setting right beside it or a ways off. Then you have to turn it off and then back on and wait for it to connect again. A real pain.
Battery Life issues etc... but GREAT sound system worth the purchase price even used!!!

Summary: Just 2 quick posts: 1. I recently purchased a "used" TDK A73 and initially was having an issue with the battery not wanting to charge. After several days plugged in directly into the outlet no power strip at all.
Summary: Sounds very good. In fact, amazingly good for a box of its size. Plus I'm charmed by its design as an obvious reference to the classic cassette tape, a product to which TDK's history is indelibly linked. The criticisms: I had a very difficult time getting the built-in battery to accept a charge.
Summary: pros: This is really a beast. In this price canegory you can't find anything better. I tryed a big viriity on portable speakers but this one is the best for that price and dimensions. Deep base crisp sound loud!(much better than anything portable from Bose!
Summary: This bluetooth speaker has really nice sound. The battery does NOT last as long as promised. We took it camping for a weekend and it lasted a mere couple of hours which was a huge disappointment. I wish the battery could last longer!
