The in-ears make a useful impression as the cable which even a ribbon cable is causing this should not tie it so quickly. The control unit is only slightly adhesive plastic. Paaring with my iPhone went smoothly and quickly.
We come to the seat, TaoTronics advertises itself these in-ears as jogging / Sport useful, this I can agree conditionally. They sit quite well in my ears but less firm than earphones which have led a cable behind the ear (as have many sports in-Ears). Nevertheless, the seat is fixed than most in 0815-Ears. The weight is not relevant.
Finally, the most important as they sound? For 29 I have to admit I was expecting not much also, I am spoiled by my Sennheiser IE80, but I was surprised. The TaoTronics sound good! Heights are absolutely clear and well resolved, the same applies to the centers which are not fully covered, to my surprise by Bass as is often the case with Cheaper in-ears.
The bass may be for some a weak point because the Tao is tuned fairly neutral, which according to the bass is more restrained (cautious does not mean bad!). So if you seek the greatest possible bass beats of all searches on;).
In general, I would say in the sound-Ears quite harmonious and fits.
Bottom line 29 a really good price for these in-ears and it's amazing how good and cheap, the Bluetooth technology has become today.
