## Questions & Answers

**Q: I have had these for a few months and the ear cup is already becoming worn. They are used daily but handled with care. Can the ear cups be replaced?**
A: There are replacement earpads for both the HD660 S and its predecessor the HD650 available from the makers Sennheiser, the replacement is straightforward and videos exist on the internet for those uncertain as to how to do it.  I found them easily here on Amazon but I imagine there are many sources.

**Q: Are these good for baroque music? do they need an amp? shall i get this model or hd 600?**
A: The HD 660S are excellent headphones and they will play any music well.  Great allrounder open, dynamic and very detailed so make sure you match them up will a decent system as they will expose a poor setup.
They need a week or so to burn in so don't be disappointed when they show up and they are a bit light weight.  They will sound great after a few weeks. They are also very comfortable to wear so you can't really go wrong at the price.  Highly recommended.

**Q: Do these have good bass extension, including sub bass (like the open back audio-technica ath-r70x)?**
A: These are monitoring headphones meaning they will have a flat response as we want this to sound as natural as possible however these start from 10Hz meaning it will be able to handle lower end frequencies well.

**Q: If i am using with a hi res dap, is headphone amp still required to drive these to get best out? and would dragonfly cobalt suit?**
A: Do you mean DAC? ? The HD660s have a fairly reasonable impedance at 150 ohms but still require a headphone amp to give them more control.
The Dragonfly cobolt is a fairly good portable amp/Dac but the build quality isn’t great in some reviews I’ve heard. I use mine with a Topping D50s Dac & a JDS Labs Atom headphone amp. It isn’t portable but sounds superb for the price point
