Just searching for some ear buds and stumbled across the Sony site where these have been heavily reduced.
Fire up your training with a 16GB music player and fitness tracker in one. Thanks to the built-in memory which stores your training program and six different sensors including GPS and heart rate monitor, you can leave your phone at home and still receive updates about your workout performance in real time. The B-Trainer for Running app has pre-set training programs or manually set your own program, plus store your results to review your progress.
Six built-in sensors including heart rate monitor, GPS and accelerometer
16GB music storage (3900 songs) with auto music selection based on your running performance
Pre-select a training program and log your workout results with the B-Trainer app
Provides customised training menus with set goals (running time, distance, calories burned, average pace etc.)
Vocal Guidance/Audio Coaching periodically provides information such as current heart rate and distance run
Automatic music selection and playback according to your heart rate.
Having to use a Sony app to sync the data…no thanks.
