All four members of this group have contradicting vocal ranges to complement each other when harmonizing.

Wu Zun's voice ranges from within the bass-baritone to the upper-baritone. Therefore, Wu usually harmonizes as the supporting voice but sings more in songs when they are intended for a lower key. Wu's voice can be easily distinguished from his accent.

Jiro Wang's vocal ranges are less wider than Wu's, but Wang has a higher voice, closer to a more tenor approach with vocal belting techniques. His voice is the easiest to distinguish out of the four because of its nasal sound.

Calvin Chen and Aaron Yan are the baritone to tenor vocalists of the group, and therefore are the predominant voices in most of their songs. Although their voices are difficult to distinguish at times, Yan's voice has a richer and higher voice and usually does the harmonizing with a vibrato while Chen's deeper and clearer voice usually does the supporting vocals. Ultimately, Yan has been acknowledged as the member with the most impressive vocal ability.

Despite having only one album release, Fahrenheit's songs mainly fall into the bubblegum pop and pop ballad category. However, songs like "Teachable Child" and "Loved" are intended for a light R&B approach. Songs similar to "The Secret of Immortality" are leaning toward the pop rock and rap genre, where they displayed their ability to rap and harmonize well.

Their much anticipated 2nd album is estimated to be released around August of 2007.
