Here is the boAt Nirvanaa Tres review this is a triple drive earphone that makes use of dual dynamic 6mm x 6mm drivers and one balanced armature driver – a total of 3 drivers.
This is a wired earphone (1.2m length), the ear buds are easy to wear and comfortable for long term use. There is In-Line Mic with Integrated controls (3 buttons + built in noise isolation mic). You can make / receive calls and also control the media.
Inside the box you will get the earphone, extra ear plug caps, pouch, card (support details). The earphone is using red and black color combination, that looks really good, especially the red cable. Cable length is 1.2m.
The L shape audio pin helps prevent cable damage. Ear buds looks different, glossy finishing black color. There are two circular patterns on the sides with red vents that look cool. The ear plugs are placed at 45 degree angle for a comfortable fit.
Now good quality triple driver earphones usually come for a premium price, this one is priced at under Rs. 3,000. Quality is too good, you get rich bass, articulate mids and sparkling highs.
You can buy from Amazon (Rs. 2,990) – http://amzn.to/2HMmBKS
