    Great Value!

    from Lancaster, CA – Verified Buyer

    This headphone from Hamilton Buhl is a great solution if you are looking for a durable headphone with a microphone. I've used other 'higher end' headphones with mics and have found that in a classroom setting they are not nearly as durable as this one. It is designed with the long-term solution in mind. Even the wrapping on the cord is designed for less breakage. The headphone is also light-weight, which is another plus. I find that the windscreen on the mic tends to impact the sound just a bit, but is not bothersome, and can be removed if needed. I highly recommend it for your piano lab or other situations where you need a headphone with a mic that will get lots of use.

    Better quality than other headsets with mics.

    from Campbell River, BC – Verified Buyer

    I have purchased numerous pairs of headsets with mics from other brands. These hamilton ones look by far to be the best quality yet. My students are sure to love them.
