Downgrade on Redmi 3 Pro

Interface: Bluetooth | Colour: White

Just bought these as a replacement for my old Redmi 3 Pro buds that got lost. Unfortunately this is a big downgrade. Really miss the QI charging of the case. The fit and balance of these are quite different making them very prone to fall out of your ears.
Sound wise they are much the same, although my subjective preference is for the 3s.
If you are looking for some good value buds, do yourself a favour and pick up the 3 Pro instead of these.

Disappointed

Interface: Bluetooth | Colour: White

After reading lots of reviews of this product I thought I had made a great decision. Unfortunately, have been disappointed from the outset for comfort and microphone. They are uncomfortable in my ear and continuously fall out no matter what I do. i use headphones for making calls a lot and every single person said I sounded muffled and underwater and have had to go back to just holding the phone like the old days.
On a positive when they stay in the sound quality is fine.
Cannot say I would recommend but from the online reviews I am in a disappointed minority.

Good sound, easy to exercise and sleep with

Interface: Bluetooth | Colour: White

quite powerful, good sound across the spectrum, they're never going to be Apple Airpods and they don't try to be. For the price and quality they make a good pair of ear buds that don't mind if you sweat or get rained on.

Best 100 I've spent on headphones in a good while

Interface: Bluetooth | Colour: White

Positives:
+ Great sound quality, nice even sound and nice soundstage for the money paid
+ I've never had an issue with battery life, but having said that I don't have these in for more than 2 hours at a time.
+ Never had issues with BT connection
+ Comfy as, they never fall out of my ears
+ The NC is really good, I ride a bike in traffic and it really cuts down the sound.

Negatives:
- The microphone is really muffled so I have to put my phone on speaker when calling
- These are loud so if I'm listening at night, the lowest volume is still a bit much for my young ears
