The functioning prototypes have already been developed at this point and the shipping will begin from January 2015.
The team of engineers behind the Earin has claimed that they are world’s smallest wireless earbuds. This team was led by mechanical and design engineer Olle Lindén and their main mission was not just to produce something that would just get rid of the messy and tangled wires but would also fit as if they were designed for every ear perfectly. All this bundled together inside the Earin helps it to deliver the finest quality of listening experiences of all times.
The buds merely weigh 5 g (0.17 oz) and have a plastic casing with a silicon tip on the end which creates the highly desired snug, noise-isolating fit inside the ear. They are 14 mm (0.55 in) in diameter and 20 mm (0.78 in) in length and with these measurements, you can also bet that they are smaller than the rest of the earbuds which you have tried in your life. The Earin connects with Bluetooth 3.0 and 4.0 and then wirelessly streams audio from a paired device. The balanced armature speaker featured on these buds has the same capacity as those of the hearing aids. This allows them to achieve higher outputs while staying energy efficient and small at the same time.
They earbuds feature a 50 mAh rechargeable Li-Ion battery which is going to last for a good 3 hours at a stretch. The best part is that their storage capsule (which weighs 25 g (0.9 oz) and is recharged via a USB cable) has been equipped with a 100 mAh Li-Ion battery that can recharge the earbuds when they're placed inside.
The functioning prototypes have already been developed at this point and the shipping will begin from January 2015. The Earin buds and wireless charging capsules would be available for early pledges of £99 (US$168) on Kickstarter.
