As someone with no experience with wireless earphones, I was allowed to test the Teufel Airy TWS Pro. The packaging looks solid and clear, which gives a good first impression. The manual is available both on paper and digitally and the description is clearly arranged and logical. What is noted is that the time indications are very small and therefore slightly more difficult to read. However, you do need this information for correct use. The digital manual is a nice addition to the entire package and also a solution for the elderly reader who has difficulty with small letters and numbers.
The sound quality is very good: clear and full, with a nice balance between high and low tones. The earphones are comfortable and stay in place, even when moving.
