HD 350BT

good basic headphones

great headphones for just straight forward listening, bit lacking in the bass department but fine for the price

Love the headphones

Over the ear, soft cups and extremely comfortable!

A good headset indeed

Even though this headset is not the most professional one, of course, it is a good choice for those who need a headset to use on trains, at work, at the train station and so on.

It has no noise cancellation, which is good because I don't need nor want to get isolated at work or on a train, but it actually isolate a bit the user from external noise. You won't feel deep silence, but I feel isolated enough to keep music and podcasts at a low volume. With the ear pods I had before, I had to keep volume near maximum.

About the bluetooth, the headset may be connected to a maximum of two devices. Only one device at a time will be able to stream audio.

It has a microphone, and an audio feedback, no problem to report on that.

Audio quality is also good, both lower and higher frequencies are not distorted at all. That is very good indeed, most of cheap headsets would get rusty on lower and/or higher frequencies.

If you are not a professional, it is a best buy.
