Summary: I thought this might work good with my 5.1 computer sound system. It does okay but with limited HD station reception. Other reviews at other sites say with a good power adapter and/or FM antenna modification this unit works great. Neither solution worked for me. Disappointing, but I guess I'll keep it and find a workaround. I get great!
Summary: It was not clear from the description that there is no provision to connect the tuner to an external antenna system. For FM, the unit uses a single 2 foot internally connected antenna wire. I tried the unit in the intended location using the antenna wire and while it was able to tune the base FM station, it was unable to locate the associated HD stations - the reason I bought it. My Sony XDR-F-HD unit does a wonderful job connected to my external antenna system.
Summary: The HDR-650 fails to adequately perform its only function, tuning FM and AM radio stations. The FM tuner will receive only strong signal FM stations and will decode HD FM from only very strong signal stations. It performs much worse than the least expensive component FM tuner. The AM tuner performance is substantially worse, failing to clearly receive even strong AM signals. The fixed FM wire antenna is typical of table radios.
Pros: Easy To Set Up
Cons: Extremely Weak AM Tuner, Small LCD, Weak FM Tuner
Summary: First let me say that I am no expert in the field and this is my first HD radio; with that said, I am really happy with my purchase. The unit is small (5" X 3" X 2") and works well. I purchased this unit to replace my portable CD player/radio that I used at work. I just plugged my computer speakers into the headset jack and wellah, an HD radio! I am bummed that hdradio.com advertised a bunch of HD stations that I just can't get.....I think b/c they aren't up yet.
Pros: Clean Sound, Durable, Easy To Set Up, Good Power
Summary: The 650 HD Coby Tuner is a special few high performance tuner you can get. Who need a radiowhen a comp tuner will do. Out of the box it exudes quality. If you own a big powered boombox with a media aux your in for an audio treet to your ears! Alot of choices out there but coby used to be known for cheap electronics. Now they have matured. Now they shed the stigma & have innovative well made electronic devices. I got one of their radios. A CX-90! COOL DUDES!
Pros: Accurate Controls, Clean Sound, Durable, Easy To Set Up, This is a tuner Dudes
