PC-Mobile Retractable Hands-Free Audio Adapter
In the Box
The kit contains a retractable cable with a Samsung 2.5mm connector at one end, and a multipurpose connector at the other. The connector includes a microphone, answer/end button, volume dial, and a 3.5mm socket that will accept stereo mini jacks commonly found on headphones. The kit also includes a single earpiece with a 3.5mm jack to make a complete handsfree kit when you just want mono phone usage rather than stereo music usage. The earpiece can be worn as bare rubber-wrapped metal, or with a foam cover. The earpiece is round, unlike the included Samsung earphones which have a pimple at 2 o’clock that disagrees with my ear’s shape and causes pain within 30 minutes.
Answer/End Button
The answer/end button works perfectly with the i700, it will awaken a sleeping phone to make a call if you haven’t locked your i700 down to the power-on button only. It brings up the dialer if the phone is awake. Incoming calls can be answered with a single click even when the phone is locked. A single click also ends calls. Due to Samsung design, there is no way to make the answer/end button trigger VoiceSignal.
Volume Knob
While easy to locate and move, the volume knob does produce the static typical of 10 cent pots while being turned. The signal is solid without crackle once the knob rests.
Microphone
PC-Mobile’s microphone seems to passively suppress background noise, as callers reported less background noise with the PC-Mobile kit than with the i700 directly or Samsung’s earphones. Yet, PC-Mobile makes no claim that the microphone is noise-canceling. It appears that this limiting occurs merely through the reduced frequency response of the components in the PC-Mobile kit. When I switched between the phone directly, the Samsung earphones, and the PC-Mobile kit, callers found the PC-Mobile kit to produce the most muffled and distant output when worn casually. When the PC-Mobile microphone was lifted directly to my mouth, callers reported a clearer and louder sound than the phone itself. Unfortunately, it’s not in our nature to fuss with headset microphones that way. However, these comments are from callers who were asked to be specifically critical of the sound quality of our call, as opposed to callers who were unaware of what I was using to speak to them. I have never needed to repeat myself or heard any complaints of low volumes from any casual callers. The Samsung microphone from the earphones produces a hissy white noise, but offers slightly more volume. Talking directly into the phone produced sharply higher volumes, but background noise was similar to the Samsung earphones. That said, the microphone does perform well within reason without making the PC-Mobile adapter useless as a handsfree kit.
