The headphone comes with two cables, 1.5m and 3m length, but they are both single ended, you have to buy an extra one if you want to go balanced. The HD650 is modded with the Custom Cans, copper - weight mod that only affects bass technicalities without altering the frequency response.

I was taken by your super review of the FIIO Q7,so had decided to go for that Dac amp,Possibly I need to look at other partnering Headphones?I was not going to go down the tube amp route but if you could possibly give me a couple of alternatives would be very much obliged The second movement of Rachmaninoff's second piano concerto opens with a series of slow chords in the strings, then the piano enters playing a simple arpeggiated figure and then the main theme is initially introduced by the flute, before being developed by an extensive clarinet solo.

What’s it like to use the Sennheiser HD 660S2?

I advise against third-party earpads since all of them, without exception, ruin the sound. Comfort and isolation

The 660S2 is drawing me to everything. In a similar way the ZMF Caldera does. Nothing is missing in my opinion. Nothing is too much. The timbre is there. The musicality is there. It is detailed. The bass is there. There is not an annoying V shape. 80% of the music is in the mid-range and the mid-range of the 660S2 is exactly what it should be. The bass and treble act as accoutrements. The top and bottom frequencies are super well integrated with the mids. They add color to the mids. Not too much and not too little. Siegfried: Getting access to your playlist reminds me so much of the cassette playlists you would make for me. I did not know what the words meant but I enjoyed the music. I remember you asking me to stop singing “Walk on the Wild Side” in public. Seeing you blush was worth whatever I was saying. On that note, MM it is time to compare the 660S2 to the 660S.It is not harsh or fatiguing but it is not as smooth and controlled as the 660S2 while it has the tendency to sound thinner, a little metallic and artificial with a rushed decay over time so percussion instruments don't sound that naturally shimmering. The mids are the bread and butter of the HD 6xx series of headphones. The HD 660S2 are no exception. There is no right or wrong here and as always, listening habits and preferences will help you to choose the right headphone for you. At just 260g, the HD 660S2 aren’t exactly heavy (Beyerdynamic’s Amiron headphones are 340g) and they don’t weigh us down during testing. Out of the box, it’s worth noting the clamping weight is a little on the firm side, but there isn’t too much pressure and over time we’d expect this to relax a little.

The way the HD 606S2 handle the midrange and voices is a real highlight. Vocals sound super-smooth and ooze refinement. Play A-Ha’s MTV Unplugged version of Take On Me at 24-bit/94kHz and the Sennheisers paint a beautifully intimate picture. Morten Harket’s smooth tone is both captivating yet gentle with it. The accompanying instruments such as the guitar and piano are extra ingredients that add to this soothing rendition. Let me reiterate, that I have no skin in the game. I do this for the cognitive brain orgasm I get out of analyzing what I enjoy. This is a joy to write, and I hope informative for the listener. As a whole the timbre on the 660S2 is more natural and realistic throughout the whole frequency range, this is a more serious sounding headphone when the 109 PRO is more youthful, fun, dancing and partying.

Treat them with consideration where your source of music is concerned, and the Sennheiser HD 660S2 have plenty going for them

Main: Roon -> iFi ZEN Stream -> Musician Draco ->Feliks Elise MK1 -> ZMF Aeolus (Sapele), Atrium (Aged Cherry) The HD660S2’s mids are clear from the middle of the mids, like 300hz-ish, all the way up to the 3.5khz area and are linear like the HD560S.
