Frequently Asked Questions
How often should I use CoreTrim™?
Yes!
Cloudbuds™ was specially designed with small ear canals in mind.
They're ultra-slim, super lightweight, and sit gently in the ear, without bulky stems or tips that cause pressure.
Perfect if regular earbuds like AirPods just don’t work for you.
Will it actually help with belly fat?
CoreTrim™ is designed to stimulate and engage your core muscles. Used consistently with light activity, many customers report an improved waist appearance over time — it works best as part of an active routine, not a standalone fix.
Is it comfortable for beginners?
Yes. Start on the lowest of 6 intensity levels and increase gradually as you get comfortable.
Is it rechargeable?
Yes — built-in rechargeable battery with USB-C charging, good for up to 2 hours of cordless use.
Is Cash on Delivery available?
Yes. Cash on Delivery works across most pin codes in India. You can also pay via UPI, debit card, or credit card at checkout. 7-day returns, no questions asked.

Pooja BhVerified BuyerFits perfectly and stays put. The sound is great too!

SalmanVerified BuyerI work in a call center and have to use an over the ear headset, these earphones are so small and so comfortable that I can use them UNDER my headset and literally have NO pain or discomfort while listening to music or audio books, I have used them for phone calls, perfect sound quality! I got the by-one-get-one, so I got one set for when I am working at hone and one set for the office.
-
MansiVerified BuyerI never leave reviews but I’m honestly so impressed especially for the price! I’m a true Apple girl and religiously use AirPods however they fall out of my ears alot so I’ve gone through several pairs. I decided to try these and they are so much better. They are small, don’t fall out, don’t hurt my ears, and I can lay down on my side with them in! Definitely will be buying more.

DeekshaVerified BuyerIf I could, I would give them 10 stars ! Trust me when I say I have drawer full of earbud fails. Friends need earbuds, I just tell them to come over and take their pick. Bose. JBL, Apple, and every off brand you can name. They either don’t go in my ear, don’t stay in my ear or my ear starts itching within a minute.I got in on the BOGO deal with these. They arrived in ten days which I thought was pretty good. They did everything they said they would! Came 85% charged, paired right out of the box and delivered awesome, crisp, clear sound. No falling, no itching best purchase I’ve made in a while !

RiyaVerified BuyerI have small ears, plus sensitivity to different things. These are the only earbuds I’ve ever found that fit my ears, don’t hurt or annoy me even laying down on them and they sound great! They don’t fall out either. I keep a pair under my pillow so I can watch videos in bed while my husband sleeps, or fall asleep to audio.
