I am somewhat rekindling my interest in HD radio. I have often thought about a Best Buy Insignia NS-HDRAD. As I was doing a bit of searching, I ran across this article. I knew that there was two different version of this radio, but now I realize that there are actually three different versions of this radio.
I have the version A of the Insignia. Sound quality isn't great over the speaker but it's OK with headphones.
The Sangean HDR-14 in the same price range has better FM reception, adds the AM band and decodes AM HD Radio stations, at least the few that remain. The small speaker doesn't sound any better than the one in the Insignia but the build quality and controls feel better.
Just to possibly broaden your search, there's also the Sangean HDR-16 which is more expensive and quite a bit bigger, but technically still portable. If you want something that sounds good without using headphones, the HDR-16 has much better sounding built-in stereo speakers.
The HDR-14 is closer in size to the Insignia you originally posted about, though. It's the one you can most easily carry around.
That is also a great point. I did have one of the Sangean HDR-1 radios years ago. I ended up selling it to a friend because I didn't use it very much. It is/was a great radio. Part of me might want to get one with an external antenna jack.
I have an HDR-16 and an HDR-18. I find the 16 to be an excellent portable radio. As was said, it is not nearly as small as something like the 14 or the Insignia you're looking at, but the tuner is _very_ good and it's still _much_ smaller than a 'boombox' of any sort. I use the 16 as a nightstand radio and an around-the-house portable all the time.
