The HD560s works very well with my topping dx1. This headphone is very neutral with a moderate soundstage.

This Topping DX1 works well with my DT880 250 Ohm. The DX1 cancels the bass distortion which I heard from directly plug into my laptop. A very compact but powerful portable DAC with just fine AMP.

It seems that drive the DT880 to 110 dB at 1 kHz needs https://www.headphonesty.com/headphone-power-calculator/?q=eyJpbXBlZGFuY2UiOiIyNTAiLCJsb3VkbmVzcyI6MTEwLCJzZW5zaXRpdml0eSI6Ijk2Iiwic2Vuc2l0aXZpdHlNZWFzdXJlbWVudCI6IndhdHQifQ== 26 mW power, I think 50 mW @ 300 Ohm should be OK for DT880

Why DX1 attract me than DX3pro+ is because it take only 79 dollars in China's Taobao, while DX3 pro+ is 173 dollors.

Thanks for your comment on it. The DT880 is 250 Ohm and 96 dB/mW. Maybe I could buy some amp in the future. I suppose that if I don't equalize DT880 Ohm, the power should be enough, right?

Hi, all. I'm using the bayerdynamic DT880 250 Ohm and my budget is no larger than $200. I got a Topping DX1, is it powerful enough to drive the DT880?

Hi, for my own experience on HD660s, IE40 pro, Fiio FD5, Cx80s, ER4SR, HD660S & ER4SR are the most not fatiguing and natural of them. Both HD660s and ER4SR are smooth, and almost no sibilance!

It looks good, excatly. This is a good IEM after such failure product, from ie 400 pro to 600pro or the newest ie 300. But for 1300 Dollars? Too expensive maybe~~~

1699 Yuan in China, about 262 dollars

For my side, Hd58X is similar to HD660s, is a more proper comment. The release date of them is HD 580X after HD660s, and 660s after 700

I dont think it worthy. HD58X is similar to hd660s, they share a same energy transducer techniques. Of course they are not the same, but consider the cost of them, dont bought both of them. In my opinion, for HD600, 650, 660s, one is enough. But if you are a new ethusiast in Hifi, buy HD660s...

Hi, have you try HD660s?

It will cost about 50 dollars, I dont want to pay for it now.:L3000: It is really lucky that hd660s is easy to drive.

I got my ifi zen dac just now. The build quality is exellent. The power is enought，for balanced cable. I am not so sure it is far more better than dc04 or just plug in the computer

It seems that Focal Clear is a good headphone. But the price of Focal's product is too high for me!
