Completely wireless earbuds don't just look futuristic - they are the future. The advanced technology that allows your cable-free lifestyle works in milliseconds. The digital signals of the audio source are decompressed and converted into sound waves and vibrations. Based on how these audio signals are handled, we can differentiate between two different types of true-wireless earbuds:
-
Conventional earbuds: these models have one primary earbud that acts as a bridge between the audio source and the secondary earbud.
-
High-quality true wireless earbuds: these models are equipped with a signal system for each earbud, thus ensuring a stable connection wherever you are.
With Sennheiser, both earbuds of the in-ear true wireless earphone come with the advanced technology to connect with the signal system. Aside from the touch controls for volume and calls easily accessible readily on the earpieces, what really improves the listening experience is the earbuds case, which functions both as a practical storage case and a charger.
Sennheiser true wireless earbuds have an integrated battery that is charged via the earbuds case when you put your earbuds away. This, in turn, can be charged via the supplied cable just like any smartphone. When you are not using your earbuds, remember to store them in the case and they will automatically recharge and be ready to use at any time.
