I purchased JBL T110 In ear earphone from amazon for inr 600 sometime back.
The sound was really good when I first time listened to them but within a week time the sound started to get pathetic. The base was really good in the starting but after just a week The base was all damaged and the sound became just pathetic and the lyrics was not clear.
I could not use them and I complained on amazon as they were in warranty period and amazon agreed to return them and I ordered boat earphones for nearly the same price which are working perfectly fine and it has been a month now that I am using them.
Overall the sound quality of jbl is already really good but the built quality of these earphones is not very good as a good earphone sound wont get spoiled in just a week time.
I have also JBL bluetooth speaker which are working really fine after 2 years I have no bad feelings for this brand but just for this product as it didnt worked well for me.
I also do not recommend to buy this product as it may get damaged really soon!
