At first I was skeptical becuase of the Logitech brand. I associate it with mostly computer peripherals (mice, keyboards etc.). I figured, what would they know about building bluetooth headsets. Then I read some of the reviews and went ahead and bought it. Before this, I tried a several other bluetooth headsets that I either bought and returned, or my friends had. I have to say that this one fits the bill for me.Here's the good:1. The fit of this headset is very secure. It stays in place and doesn't hurt the ear. I have worn it for over two hours at a stretch. The earphone speaker feels very comfortable with a sponge jacket (and the headset comes with a couple of spares too). I have tried the motorola HS-820 headset and while that was a good headset overall, it always felt like it was going to fall off my ear. So I went and returned it.2. The phone is very easy to setup and charges fairly quickly. I was able to pair it up with my phone without any problems. The battery life of this phone is excellent (with 10 days of standby time and 7 hours of talk time).3. The voice quality of this phone is unbeatable. I have tried my friends Jabra 250 and my earlier Motorola...the sound quality on this one is superior to both. The other side is always able to hear me clearly and I am able hear them clearly too. There is no static, unless I go greater than 10 feet away from my phone. I guess the clarity is because of the "windstop" technology, but honestly, I don't care how they do it...it ends up sounding pretty good.4. You can't beat the price. At $40 (or so), it is less expensive than most headsets with similar features, on the market.Here's the bad (or "nice to haves"):1. This is somewhat heavier than the other headsets I have tried, but like I said earlier, I have never had a problem keeping it on for long hours because of the secure and very comfortable fit.2. It does not look as nice the motorolas, but hey I would rather have a headset that does not feel like it going fall off any moment.3. I have setup different ringtones for different people in my contacts list. This headset does not support these ringtones. It always play the same ringtone, not matter what. This is again, a nice to have feature. You would pay substantially more on another phone with a feature like this.All-in-all, this one of the best headsets I have found at a very reasonable price. I must say I am impressed with the overall line of Logitech products. They seem to produce some high-quality stuff.
