Thanks for the info.   Since I travel a lot, I plan to buy a case for the headphone : http://www.amazon.ca/gp/product/B00PDEZIPA?psc=1&redirect=true&ref_=ox_sc_act_title_1&smid=A2OPUAQVSPCTA3   Any suggestion for a good case that I can put in my backpack ?

Any brand or model  for the cable ?

What kind of cable do you use with your O2.   That's not the original cable that comes with the HD 650.

Yeah, I bought about it a lot and I think I will prefer the HD650 over the HD600.   I plan to try both models before buying one.

I bought a JDS O2 last week and I'm waiting to buy me second pair of Sennheiser(I'm from the HD555), the HD650.   Looking forward to buy one of the Sennheiser flagships.

One funny thing about the 770 : I don't hear my coworkers but I don't hear my telephone and it's a problem. I missed 3 importants call yesterday :) About the 880 they don't leak that much. I must said that between me and my coworker we have 6 foots between us and I added a 6x4 division wall so...

Hi everyone, I received my Fiio E12 and my 2 pairs of headsets.   I'm still burning them and actually I'm switching them every hours or so when I'm at work.   Which one should I keep as my primary headset ?   I don't plan right now to keep them both.   Thanks :P

Yeah, I hope to check that one day too.   The DT 1770 seems to be one of the best and it's an upgraded version of the DT 770 AFAIK.

I saw that JDS labs is building the O2 model too.   On those models, I can choose the standard gain : 2.5x - 6.5x gain, the medium gain 1.0x - 3.0x and the low gain option.   Which one is the best for my headphones :   BeyerDynamics DT 770 Pro 250 ohms BeyerDynamic DT 880 Premium 250 ohms...

Which one sound the best ? The fiio e12 or the o2 ? Thanks :)

I changed my fiio e12a for a e12 just to be sure. I bought also the dt 770 pro 250 ohms. Any comments on the mayflower o2 amp only ?

Hi everyone, I would like to know which impedance I should buy for the DT-770 PRO ?   Is the E12a is able to run the 250 ohms version of it's way too weak  ?   About the amp Fiio E12a, should I buy something else to pair with the Dt-770 pro ?   Thanks for your inputs.

Can I try the 770 PRO 250ohms with the Fiio E12a ?   Or I should get the 80 ohms model ?   Thanks :P

Hi everyone, I can have a decent deal for a Sennheiser HD 598 for less then 200 $ canadian brand new.   How do they compare to the HD 555 ?

Hi, how's the sound leakge of the HD 598 compare to the HD 555 ?   I don't have any problems with my 555 at work and I really plan to buy the HD 598.   I'm using a Fiio E12A with my 555 right now.

Hi everyone, I have an old pair of HD 555 and I'm using a Fiio E12A. I didn't notice any difference in the sound beside the added bass when I enable the switch.   I have the opportunity to buy a pair of HD 598 at a really good price.   Will I notice a difference or not ?

I bought the E12a.

So in term of quality built and overall sound I should go with the p7 or one of the beyer ?

Hi everyone, is there any great deal on those :   Right now, a lot of Beyerdynamic are on sale in Canada.   Should I check for them or the B&W P7 are better then those that I found with great discount :   DT 770 PRO 250 ohms  ...

The dt1770 needs a driver for sure. FIIO e12 or e12a I guess is a good choice ?

I hear some great things about the NAD Viso HP50, but they look a little weird on top.

So I should get the e12 instead of the e12a ? I'm gonna check for a E12 then :P Also, that E12 will be useful even at lower volume I guess ? Since I use them at work only, I don't want to bother my coworkers and I don't want to become deaf. If I understand the device, it's a device that...

Hi everyone, I read somewhere that using an Ipod with some really nice headphone can be hard sometimes.   I also read that some preamp and DAC are there to gain up the signal and help to have better performance.   So, I would like to know which unit is the best with a Ipod Touch 5th...

I would like to know if the Sony MDR1ADACB Premium High Resolution Headphone w/ Built In DAC and Amplifier are good or not ?   http://www.sony.ca/en/electronics/headband-headphones/mdr-1adac   I found a big discount right now in Canada.     Instead of 350$, they are less then 250$...

Thanks for the input :P   Are they good those : Sony MDR1ADACB   http://www.ncix.com/products/?sku=106034&promoid=1111   I just found a big discount on those this morning.
