Motorola Razr2 V9m On Sprint Cell Phone Review - Audio Quality
General Audio
Sound Receive Frequency Response (7.48)
The chart above shows the frequency response of the sound received by the Razr2 V9m. This is how other people sound to you while on a call. The blue line shows the Razr2 V9m's performance, while the two red lines indicate the limits against which we test. As you can see, the Razr2 V9m generally stayed within the limits, with just slight deviations along the mid ranges and falling off a little too quickly at the high end. This means voices should sound generally clear and accurate, although they might be slightly clipped. Overall, the incoming audio performance is good.

Sound Send Frequency Response (7.16)
Sound send frequency response is a measure of how well the Razr2 V9m transmits your voice to those on the other end of the line. The chart above indicates the Razr2 V9m's performance with a blue line, while the two red lines show the limits we test against. As you can see, the Razr2 V9m has some issues, with lower frequencies being somewhat suppressed and high-end frequencies exaggerated. If you have a deeper voice, people on the other end of the line may have trouble hearing you, while the exaggerated upper frequencies could make your voice sound overly reedy. As you can see from the table below the Razr2 V9m comes in at the low end compared to other devices; it is adequate, but not particularly good.

Handset Side Tone (9.31)
Side tone is the small amount of your own voice piped back into your ear so you can judge how loud you are speaking. The chart above measures the side tone of the Razr2 V9m across a range of frequencies. We were pleased to see the Razr2 V9m averaged 17.31 decibels, which is very close to the 18 decibel ideal against which we score. As is illustrated below, the Razr2 V9m put up one of the best side tone scores compared to other phones. The Razr V3m also put up a very good score in this area.
