Product Information

But then it has a slightly different tuning than its older brothers which is not necessarily better or worse, it is just new and different. The non-fatiguing HD 660S2 gives people who love music an intimate way to connect more deeply with their favorite songs and artists. Breath-takingresolution and precision take you closer than ever to instruments and vocalists. Yet the sound is natural and balanced, never harsh or brash. This warm, inviting signature combined with extended sub bass makes listening uniquely pleasant and rewarding.” Unfortunately, the price is higher than I consider “apt.” The MSRP is exaggerated for a product that is a slight upgrade over the last model – primarily offering improvement in the bass for existing HD 600 and HD 650 owners.

Additionally the texture is weighty and rounded, not as dry and thin as the HD660S while it decays in a more relaxed way helping instruments to sound full bodied and realistic in their reverberation in time and space. The other thing I’ve noticed is that the HD660S2’s have a shorter cable than the HD660S’s, and I’ve grown fond of bringing the S2’s with me everywhere I go now. The HD660S’ longer cable 3m cable was great for walking around, but the HD660S2’ 1.8m cable I felt was a lot more manageable to have instead. Outside the Sennheiser ecosystem, the HD660S2 is an undeniably excellent sounding headphone with supreme technicalities and a balanced, realistic tuning that offers plenty of musicality and emotional involvement and as such it directly compares with similar or slightly more expensive headphones like the HiFiMan Ananda Stealth or the Meze 109 PRO. Below you will find some useful information about the design principles and the technological innovations of the HD660S2 as provided in the Sennheiser product brochure.On a technical level, the HD660 S2 also scores well. The smoother tonality doesn’t stand in the way of the precision, extension , and overall detail retrieval. As expected from Sennheiser, the dynamics are excellent as well. Also impressive is the left-right balance and stereo imaging, it’s a joy to the ears. You get a perfect mix of body, cleanness , and precision and that combined with the smooth and dynamic delivery makes it a very musical high-end headphone. This is the first HD6xx series headphone with real sub-bass extension and not merely harmonics that pretend to act like one. measures result in even greater precision, speed, and resolution - with double the sound pressure at the The bass on the 109 PRO will just slightly bleed into the mids but it can't be said that it is overlapping the rest of the frequencies or clouding the mid-range.

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. The S2 has a deeper, richer, more textured bass compared to the 600. The treble is more forward with S2. Smooth forward rather than sparkly. The female vocals of S2 are a little richer and more forward. Everything seems more forward with the S2. But, upon a longer listen it is not that the S2 is more forward. There is a sheen of glass taken away compared to the 600. There is for sure an increase in clarity and dynamics. This adds a richness to the sound.

S2 and S time it is: Easy to cut to the chase on this one. I am truly amazed how the S2 is a better version of the S with some serious lineage going on with 600 timbre and 650 rounder notes and bass bump. All 6 series HPs have mids that are sublime. IMO most of the notes I want to hear are in the mid range. That is where the maturity of the music is at. The 6 series keeps the mids as the meat. The S2 bass is very similar to the S bass except the S2 bass has more texture. It is simply a better version of the same bass. I am not the best at talking about treble and I hear a very similar treble between S2 and S. I am not hearing any harshness with S2 nor S. But I have not met a treble I did not like. Especially after a drink or two. Not much more is changed about the midrange on the 660S2. It appears that Sennheiser didn’t put as much focus into tuning up some of the frequency response here, but that isn’t much of a complaint for me. The low-mid warmth is still persistent on the 660S2, as is the flatness and neutrality of the fundamental mid-bands. Highs However, the market has grown so competitive that the HD 660S2 do not offer everything they should at that price. For one, I expect better staging, and the bass slam could be improved. I am a fan of keeping all 6XX series HPs with the same frame and cups. Other companies like ZMF and DCA and Audeze for example do a lot of sharing of chassis and cups. The lightness of the 6XX series HPs is wonderful. The clamp can be tight for some, but it does loosen up over time or can be loosened through bending of the strap. The good news is that the HD 600S2 come bundled with balanced and single-ended cables, making it easy to connect them to various sources without having to buy an aftermarket cable. Design

Microdynamics (gradual shifts in volume) are excellent, on the other hand. Separation is also above average, but some mid-range planars (e.g., the Hifiman Ananda Nano) are better. The HD660S2 benefit from a dedicated amp that can drive high-impedance loads. Comparisons Vs Sennheiser HD 650At 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. It is not that you can't listen to classical music but the instruments sound slightly out of tune and emphasized compared to, the already slightly colored, 660S2 which comparatively is more in-tune sounding.
