(Pocket-lint) - Samsung has officially announced its Level range of mobile audio products for international release. These "premium audio products" include Bluetooth speakers and headphones.

The new categories comprise: Level Over headphones, Level On headphones, Level In earphones and Level Box Bluetooth speaker.

We got a try of Samsung's new over-ear cans back at Mobile World Congress 2014 and were comfortably impressed. These, we've now learned, are called Level Over which pack 50mm Dynamic Drivers into the over-ear Neodymium design. They use wireless Bluetooth connectivity and have an S Voice friendly built-in microphone.

The Level On is a slightly more compact, wired version of these cans packing a 40mm dual layer diaphragm and microphone.

Level In is a set of in-earphones with three-way sound that lets "users enjoy rich sounds that cover all the low, mid, and high sound naturally and with clear sound separation," says Samsung.

Level Box is a compact Bluetooth speaker with a 56mm speaker and passive radiator with built-in microphone for calls and noise cancellation for echo reduction. The Box works with NFC to pair and features a 15-hour battery life, according to Samsung.

The Samsung Level series of products will be available internationally from mid-May when pricing should be confirmed.
