These lightweight earphones will stay put, while you exercise vigorously.
I am a rather late convert to exercise machines and straightaway, I had a bone to pick with people who talk glibly about 'music while you workout', using the earpieces supplied with most smartphones. Spoiler Alert: They don't stay in place. They pop out from your earlobes, get sucked into the treadmill or otherwise prove to be a nuisance. I have been using Digitek's DBE-001 and 002 earphones for a few days now during my hour in the gym and yes, they understand and address my pain points. Of the two the DBE-002 costs just a hundred rupees more than the 001, at Rs 995 and the extra money buys an extra firm grip on the ears.
Being Bluetooth, you can sync to your phone, while it is stashed away safely in your kit bag -- or as I prefer, in the receptacle they thoughtfully provide on treadmills. Both earphones belt out 18 MW of power and on a full charge can work for around 2 hours as a music player and 5 hours as a phone accessory. The controls are easily accessible along the generous 80 cm cord. With St Valentine's Day coming up in a few days, I can see people seeing in these earphones an affordable, yet thoughtful gift.
