The ability to monitor and evaluate the quality of your recordings in the field is absolutely essential. The loudspeaker incorporated in the recorder (if present) is not adequate because it can only be used in the playback mode. Good quality headphones allow you to monitor the incoming signal while the machine is in the record mode, thereby facilitating proper aiming of the microphone.

Additionally, by using a pair of headphones you will know if there is a problem with your equipment. A bad cable, A recorder that is not turned on and other problems can be identified and maybe fixable at the time of the recording. This is generally better than dealing with the disappointment of a flawed recording discovered hours or days later.  

The choice of headphones is highly personal as to style, isolation, and comfort. The model selected should also offer some degree of isolation from ambient noises so you can listen accurately to your sound source.

A few of our favorite headphones are the following:

• AKG K-240 Studio (high isolation rating and good output) $159
• Sony MDR-7506 (good isolation rating and high output) $95
• Sennheiser HD-25SP (lightweight with medium isolation rating) $113

It is important to note that with many cushion-styled headphones, some insect repellents can disintegrate the foam cushion material.
