dodocool In-ear Virtual 5.1 Surround Sound Stereo Earphone with Remote Control & Mic Gaming Headphone for Xbox One PC Tablet Laptop Smartphone and More Black

Its very big in ear for normal ears!!! Bass is really good,, as mentioned can hear upto 10 hz and low frequesncy....bass response is mind blowing,.. very loud and durable as well!!!

The earbuds is put in a small wallet with plastic earbuds replacement and a cable. The sound is good. It is very convenient for travelers. RECOMMENDED FOR TRAVELERS.

For the price these are some amazing sounding earbuds. Rich full range and deep bass response. They come with a miriad of earbud sizes for all types of ears. The only fault is the loop that sits in your ear. When you tug on the wires, the loops shrink. For the most-part that's not an issue but I could see this happening while running or doing other sports.

I like these headphones. They fit quite nicely in my ear - secure but not squeezed in. There are a few different size coverings for the buds, so you can find a bud that is comfortable in your ear. They work well with my iPhone 6s. No connectivity issues. I think the sound quality is good. The sound is solid, crisp and clear. It looks quality made as I have not had any issues with the headphones themselves. The wiring isn't fraying or losing connections - all good. I love the little case that they come in. It makes it easy to travel with them All plugs, along with the headphones, fit nicely into the case. I believe you will be happy with your decision to purchase these.

These have some of the best sound I've heard in a $20-$30 pair of headphones.
