Great sound!
I use these at the gym and while walking, the sound is excellent and the noise cancelling feature is a huge plus. They also fit perfectly in the ear.

One of my favorite earbuds
This is my 3rd earbuds from Sennheis. Battery life is really good and sound is fantastic. When I talk on the phone through earbuds , the person on otter side hear me perfectly. Nice earbuds for the price. Will buy again.

Great product
Good sound quality. Only drawback is that it connects to one device at a time.

Great for the price. Great sound quality
I bought these on sale and used some Store Cash so I paid very little for these. The sound quality is fantastic and it's easy to connect to my phone via Bluetooth and manage via the Smart Control app. I sleep with them in as I listen to podcasts/meditation music overnight. They are a little clunky in my ears, hence the 4 stars, but I'm getting used to them. I'd buy them again. The battery lasts approx 9 hours and they are easy to charge with the case and the charging cord included. You will need a wall charger plug to plug into a socket or a USB socket.
