## Description

From the manufacturer

Review: Best in Budget - Very good product. I purchased it 6 months ago, and it is still working smoothly without any issues. The battery backup is impressive, it lasts for a long time on a single charge. The sound quality is also amazing for this price range. The bass is clear, and the calling quality is good with clear voice output. Overall, it is a value for money product. I would definitely recommend it to anyone looking for good earphones within a budget product
Review: Review - I thought It will be worth for the money but nope but comparing to other model it's good with performance and durability with strong build and a good look and good sound clarity with Enc so it's a good product but not up the price and Main thing is it's not working in their own goboult Amp and even while scanning it's not visible so better to choose some other models for better performance but under 1000rs range this k40 is ok
