Headphones
 
Audio Technica ATH-M30 (w/ 1/4 in. adapter) = $4.00/day
Sony MDR-V150 (w/ 1/4 in. adapter) = $1.00/day

We recommend the ATH-M30 headphones for professionals for their excellent frequency response and sensitivity.  They fit over the entire ear.  

The MDR-V150 headphones are for high-end consumers.  They’re great, but not nearly as good as the ATH-M30.  They also don’t fit over the entire ear. Audio Technica ATH-M30 (left) and Sony MDR-V150 (right)
