When you turn the headset over, you'll find a simple, small earpiece that sits just at the opening of the ear. There's a rubber coating around it so it feels comfortable. We would have appreciated different sizes of ear bud covers for different-size ears. Even though the Samsung WEP470 does fit comfortably, it doesn't feel very secure. We definitely recommend using the included optional ear hook for additional stability.
We paired the Samsung WEP470 with the Apple iPhone 3G. The pairing process was very smooth and we didn't even need to enter the PIN-pairing code--this may depend on your phone, though. The call quality was quite good for the most part. On our end, we heard our callers just fine, but we did encounter intermittent static buzz. Still, their voices sounded natural and volume was good.
On their end, callers could hear us loud and clear most of the time. This was especially true in a quiet office environment, where background noise was minimal. In a moving vehicle, though, callers said they could hear a bit of background hum. Similarly, it didn't cut out all the environmental noise when we were in a busy cafe. The WEP470 also does not do well with wind noise; conversations were close to impossible in particularly windy conditions. However, in most normal everyday situations, the WEP470 did just fine with noise and echo canceling. Callers also said voice quality was natural and almost of landline quality in the best situations.
The Samsung WEP470 features the normal capabilities to answer, end, and reject calls, as well as last number redial, call mute, and the option to transfer calls from the headset to the phone and vice versa. It has a rated battery life of 6 hours talk time and 8.3 days standby time.
