MP3 players

The 605 WiFi (30 GB) is part of the MP3 player test program at Consumer Reports. In our lab tests, MP3 player models like the 605 WiFi (30 GB) are rated on multiple criteria, such as those listed below.

Ease of use:

Ease of use mainly covers player characteristics that aid in convenience, versatility, and portability. These primarily include navigation and scrolling features; the accessibility and readability of the controls; and the readability and breadth of the information in the display (such as music-track data and battery-life indicator); size and weight; and ease of use while walking or jogging. Some features and capabilities considered include the presence of an FM radio, built-in microphone, upgradeable firmware, equalizer, data storage, software assessment, and the player's ability to be recognized as a hard drive by the computer without the installation of additional drivers.

Headphone quality:

Headphone quality reflects judgments from a listening panel comparing the player and its supplied headphone to a test audio CD and a high-fidelity headphone. All uncompressed (audio CD or WAV) test music sources were ripped (encoded) to MP3 format (128, 192, and 256 kbps CBR rate) using a high-quality encoder.

Audio quality:

Audio quality reflects judgments from a listening panel comparing the player to a test audio CD, using the high-fidelity headphone for both. All uncompressed (audio CD or WAV) test music sources were ripped (encoded) to MP3 format (192, and 256 kbps CBR rate) using a high quality encoder.
