Super Bass an Clarity, thks to flipkart for th help

Nice clarity. Bass is okay. CX 3.00 is smoother and sets up the bass more, is darker. Fun fact. This and the 275s with mic sound almost exactly the same. But those don't have L shaped jack. What's up with that Sennheiser.

This is my 3rd Sennheiser model. And as usual the performance is just AWESOME!!!!.
The silicone eartips is not properly insulating the outside noise unlike in Sennheiser cx275S model. So I have replaced them with my Sony xb50ap eartips. Now the outside noise is decently insulated.
Also it doesn't have mic.
Good sound stage. Nice bass effect. Clear sound.

This one has a good sound quality and comes with a very handy pouch for safe storage. Only thing missing is the mic.

Very Nice Product , Great Bass Great Quality of sound, Absolutely Brilliant.

And Thanks To Flipkart For quick Delivery and Good Packing Through

I've tried too many headphones, such as sony mdr-ex15ap,g45lp,zx110 & xb450 series,philips shp1900,shq1200,she3590,sho3300,jbl t250si,t100a and old one (forgot the model no and its cost was around 2000),mi(piston 3),audio technica clr100, sennheiser cx180 and lots of others.
So after one day of use ill say this headphone(CX300ii) is the best to me till now.

About its sound- look, if you are more of a music lover than a basshead then you just cant deny this headphone.
the mids are surprisingl...

Awesome product.

Sound quality is good an awesome product bt wire cables are not equal in length little disappointed with dis overall .. It is best must buy it I later bought cx180 version that was also gud. .

really good one.....
