Need a easy drive speaker while I am traveling

Would closed headphone, in-ear monitors, or open headphones work?

or a car stereo?

I do  not use headphone, I will use it in the hotel room.

Be better to have small horn speaker or any other speaker.

I would just look into a good Bluetooth speaker like the offerings from Marshall, B&O or the B&W Zeppelin. 

That's the easy way, and just like directly from phone.

Second the Marshall Bluetooth speakers.

they are exceptional in the Bluetooth category

Also look at Klipsch The One. This is a great sounding bluetooth speaker for small rooms. We use it at our mountain condo and it fills that small space easily.

 

 

@ozzy62  Thanks for your information. I will use klipsch bookshelf speakers instead.    Most of time,I do not like the active speakers, I do not know why, but I just do not want to listen.

         Maybe  it is class D amplifier inside.

Do you really care if it has a class-D amp?
 

I use a 400 dollar Sony Walkman and top Grado in ear phones....couldn't be happier
