Sony SRS-A27 Desktop Personal Speakers with 2-Way Power Supply

First of all, this speaker is for the office and not for music or entertainment. It has poor sound quality, and it sounds worse than the $10 dollar speakers I got from my brother. If you're going to be using these speakers for entertainment, do not buy these.

If you are looking for entertainment speakers, buy the 2.1 or above. Don't buy one like these.

...and that's how they get you. The Sony brand adapter is listed at $39. You can buy an universal adapter for under $20(the sony is rated at 9v and 800mA), but there is a catch. The universal adapter's plug is too long! It won't make the proper contact with these speakers. But there is a way to make them work. Find the right adapter plug and put a little piece of tinfoil in the hole of the adapter---don't put it in the speaker hole.

So, Sony uses a shorter adapter so you think you can't use the universal adapter and charges you $39 for their adapter.

You could try using a spring from a ballpoint pen or any small springs; or, cut a piece off a paper clip or copper wire, but the tinfoil is easy to use---just stuff enough into the whole to make contact. It can be scraped out if you need that plug for another device.

I had Sony speakers before, but they did not have the option of adding batteries or plugging it in...so the output was minimal. I decided that I needed speakers with more power. I looked everywhere and bought these...they seemed to be one of only a handful of speakers that would let me use either batteries or plug into an outlet (adapter not included). They were fantastic. I have read other reviews about the noise not being that good, but I have no complaints. They are not "tingy" and get very loud for such a small speaker.
My only issue is that the pair I had, the speaker not connected to my IPOD (you connect one line into the IPOD, and the line from the other speaker plugs into the first speaker, the one plugged into the IPOD) would cut in and out.
I opened up the speaker and saw that the connection came off, so I soldered it back on, but it just did not perform the way it did at first for over 2 years. I am not sure if I was too rough with them, or if it was a product flaw. This is my 2nd pair...I will give them another shot, so they were at least good enough for me to give them the benefit of the doubt. Maybe I just threw them around too much. If the same issue happens again, I know it is a Sony issue as opposed to my fault.

I use these at work and they are handy, and don't sound bad at all. They are almost indestructible as far as dropping them, I have many times, and they keep working. Amazing!

Initially I bought these speakers because they looked really nice, were made by Sony and were cheap. I guess none of that made any sense when I initally used them for music. These speakers are just bad for music. However, I got a job as a teacher a few years back and I used these speakers for audio books and they worked great.
