Kabelloser In-Ear Bluetooth-Kopfhörer für Läufer, schweißresistent, sicherer Sitz und High-Fidelity-Sound. Ideal für Sportler.

Wonderful, I suggest.

They conform to the ear like a mold. The ends are exceptionally comfortable and soft.

The sound quality is excellent and they are very comfortable to wear; they connect automatically as soon as the charging case is opened.

The seller shipped fast but the delivery was slow. The product is good. I haven't tested all functions yet but it seems to be working as advertised and very quickly. When watching a video there is very little to no delay with the sound. They are light and fit in ears well. Sound: bass lacks depth and power but is very accurate. Highs are also a bit on the low side and not very distinctive. Mids are quite good but can get a little harsh on higher volumes. With some phone app you can just tone the Mids down a bit and have a pretty decent sound (without much bass). Overall for the price they are very well working and sounding earbuds. It seems to be working very well and the sound is good. You probably can't get better wireless earbuds from Finland for around 20 euros.
