Arrela Bluetooth 4.1 Headphones are a great set of headphones, I love music and I love to have the ability to listen to music,when and where I want to. These headphones have a great clear sound and also they are noise cancelling as well. Also I can use these earbuds with a phone for when I am on the go, they have a microphone in them. I like that these are Bluetooth as well, and they have a great battery life. They also come with extra pads, in different sizes. I really recommend these to anyone who loves music, they are a great find. I would have liked it, if they had came with a carrying case though . These are a great find. I received this product for free or discounted prices,for my unbiased opinion and my opinion is solely my own.
