Synchros E10 has a good sound quality with a good mid range and the highs are also fair, it has a decent bass . The sound wont distort even at 90% volume and voice clarity during calls and of the mic is also good. One can use the headsets for long duration without getting your ears strained which is the best thing I love about this product.
Overall build quality is decent, but its wire quality is not that good. The white variant attracts dirt very easily though it is the best-looking as well.
One gets three ear piece sizes which can be used accordingly as per one's comfort but a carry pouch is missing which is usually expected for earphones in this price range.
The best sound quality in this price range was the deciding factor for me to buy this product.
I bought this from Amazon as it offered the best deal.
Overall it proved to be a great buy for me at this price as none of the competitors stand in the line.
I would give 5 stars for the sound alone at this price range for this earphone but overall its 4 star.
