Searching for a good earphone is very difficult nowadays due to large options available in market which gives us hard time and oflenly confuse us. Here are some tips for buying good earphones, Quality matters a lot- It is no matter what, is the chief deciding factor and you should go for an earphone with balanced combination of sound and bass. The sound should be crystal clear and bass must be strong and rich but earphones of such type are hard to find because extra bass earphones are in trend now. I have used skullcandy and jbl but I am using now sennheiser cx 180 as my main and flipkart smartbuy earphones as part time use and as they have balanced combination of music and bass.Extraa bass is not recommended for long run. Specially if you are using Dolby atmos( in lenovo handsets) balanced bass is just perfect and give best output with it.Durability - Durability is definitely going to matter a lot in this decision making and I have broken a lot of them just by mistake. I have broken my custom lenovo a 7000 earphones which were in the box but, those were good only for normal listening and were not good to feel the real digital sound which comes in some sound enhancers especially dolby.Go through customer reviews for durability and paying a little much is fairly okay if you are going for a recommended earphone.
