Great. well, almost - ISOtunes Sport OPMOD CALIBER True Wireless Tactical Earbuds With Bluetooth, 25 NRR

I like them. They fit great in my ears, very comfortable. Are Bluetooth compatible. The block sounds really well while shooting. The only thing I might say negative is that they are very sensitive as to when the noise canceling engages. Even a loud voice or strong wind will engage the noise canceling. Just something to consider before buying. Overall I like them for the cost.
