pocketnow reviewed Sony Ericsson HBH-610a and gave the headset rating of 3.5 out of possible 5, and concluded that “The HBH-610a rectifies some of the main problems with Bluetooth headsets. Namely, this headset is good-looking and the echo cancellation and noise reduction work well. It is held back somewhat due to the soft volume on both ends of the call and the odd way it sits on your ear. I deducted 2 points from the Ease of Use rating because of the slightly uncomfortable fit, so it’s tough to get used to. As I mentioned, you should definitely try this headset on before you buy one.
At $85-100 this headset is an average value. It is certainly cheaper than many others that do not have echo cancellation and noise reduction. Plus, you are getting a Bluetooth 2.0 product. I’d be curious to test how much better the sound quality would be using Bluetooth 2.0. If you are looking for a good-looking headset that is somewhat future-proof, then the Sony Ericsson HBH-610a could be a good choice… provided you find it comfortable to wear.”
