Need a easy drive speaker while I am traveling

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

Maybe  it is class D amplifier inside.

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

@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.

 

 

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.

 

 

Second the Marshall Bluetooth speakers.

they are exceptional in the Bluetooth category

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

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

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

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

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

or a car stereo?
