Deal insights

The Sennheiser HD 660S2 Open-Back Headphones are a Good Deal, offering audiophile-leaning open-back sound and premium build at a price notably under recent typical levels. The listening-focused audio characteristics and solid comfort materials match expectations for a higher-tier model, while the lack of ANC and wireless connectivity aligns with an audiophile open-back design rather than a mainstream wireless premium set.

Here is why

When selecting over-ear headphones, compare audio quality, noise handling, connectivity, and comfort/build. Here is how this product performs:

Audio Quality (42 mm drivers; open-back tuning; 300 ohm impedance) : This aligns with premium-tier audio expectations: driver size, open-back design and tuning are typical for audiophile models. Given the price band, the stated detail and control are in line with higher-end headphones rather than mid-range consumer sets.

Noise Handling (open-back design; no ANC) : Open-back with no ANC is common among premium audiophile headphones and is weaker for isolation compared with closed-back premium ANC models. This is typical for its segment when the priority is soundstage and natural timbre rather than noise rejection.

Battery & Connectivity (wired connectivity; no Bluetooth) : Wired-only operation is normal for audiophile/open-back premium models and consistent with premium benchmarks that favor lossless wired sound. It is noticeably different from wireless-focused premium cans but typical for this listening-focused use case.

Comfort & Build (0.3 kg; aluminum enclosure; plush earpads; detachable cable) : Materials and plush pads match premium comfort and build expectations and are better than typical mid-range builds. Detachable cable and metal elements are in line with higher-tier benchmarks and support long-term use and repairability.

Deal price at $360.95: sits in the premium band for over-ear headphones but below many flagship price points. It is priced below its recent 30-day average of about $481.93, which improves the value case for a known premium audio brand.

Overall, this Good Deal suits listeners seeking a wired, open-back, high-fidelity listening experience and who prioritize sound quality and comfort over wireless features or active noise cancelling. Great for home or desktop listening paired with a good amplifier or DAC; double-check return policy and warranty when buying at a discount to a known premium price.
