Recently I am buy this product Mivi collar classic from flipkart but when I check the website all features are displayed like this is the perfect under budget earphone that give best quality results.My main intention to buy this earphone is calling & battery life & this earphone support fast charging have great battery life but if you talk on call where is the noise cancellation I thin Mivi Forgot to give that feature in the earphone call answered person always told me turn off your earphone and then make call or use handset speaker to talk with me getting lot of noise form your background.This product quality-wise really good work form Mivi earphone wire quality is good also built quality is also great but disappoint on the noise cancellation.If Mivi fix this issue then this is the great product in the online market list.Also my right side earphone speaker is also not working sometime am get sound sometime not now am talking with customer care to change my earphone because its in under warranty.literally dont buy this product I am never suggest to my viewers t buy this product.
