Beat QPR !!

These are intras for TOP 1/2 and their qualities / to the sale price that make it one of the best in the market today QPR (hence my rating of 5 *). Comparing with much higher prices of ITE and reputed brand (hifiman, Sennheiser, Philips), the price difference is not justified. The quality will be better but it's REALLY not proportional. The TX1 is top for portable use / leisure and even a little more.
The sound is clear, precise, pretty well balanced and very warm.
The insulation is pretty good although it should be noted that friction cables (flat) is heard during playback. But it's really not very difficult.
Ergonomics is fine for me (specific to each cf other review on the product) and many different tips to help the suitable adaptation.
Very happy with my purchase, I do not regret even if I was quite ready to spend more initially.
