The Sony SSE-BTR1 Smart Trainer 16 GB Waterproof All in One MP3 Player can be your very own personal trainer, as well as working as a traditional all-round MP3 player.

Efficient personal training

Listen to music whilst receiving regular, informed voice guidance and encouragements, in a compact, stylish and comfortable body.

Using the app, simply select a training menu according to what you want to achieve. Whether you want to lose weight, build endurance or prepare for an important race, the Sony Smart Trainer has a specially researched option for you.

Let your heart rate dictate the track

Whilst training, the SSEBTR1 Smart Trainer headphones take careful recordings of your real-time heart rate and if it is too high, it will automatically select and play a more chilled out piece of music or song. If your heart-rate is a little low and your Smart Trainer feels like you have the capacity to push yourself harder, an upbeat, heart rate rising track will automatically come on, giving you the final push you need to beat your record or reach your goal.

11 types of running logs

When you have completed your run, your GPS recorded running log can be viewed graphically. You can check your summary data through graphs, lap times and even your music playback list so you can evaluate what was working for you, and what wasn't.

It measures heart rate, calories burned, distance, time, pace, pitch, strides, running route and altitude – you really do have a rounded training system in the Sony Smart Trainer headphones.

Comfortable and secure

With five different size ear-pieces that come in each pack, you can really find the one that fits your ears. It is important you find the right fit, not only so you can run easily, without having the distraction of a loose headphone, but because your heart rate is monitored through these clever little ear pieces.

The Sony SSE-BTR1 Smart Trainer is even sweat resistant and waterproof (meaning you can wash them and use them underwater).

If you fancy using them out when you're not running, these headphones have you covered. You can choose the audio playback function for listening without the regular training updates. In this function, with GPS and Bluetooth switched off, the Smart Trainer has an excellent battery life.

For a fun, new way to train and see impressive results whilst listening to your favourite tracks, consider the Sony SSE-BTR1 Smart Trainer 16 GB Waterproof All in One MP3 Player.
