Though with a heavy focus on wireless tech now days, I think it is easy to overlook the benefits of wired technology. Yes, wireless devices are way more convenient but you cannot defeat the stability and quality that a wired connection offers. Enter the Sennheiser HD 620S headphones. Certainly, it is primary aimed at a slightly younger audience who may not understand the benefits of wired audio — these headphones virtually manage to convince you that being connected (literally) might still be worth your while.

Design and Build: Durability Meets Comfort
Design and build The Sennheiser HD 620S is an over-the-ear style headphone which has a robust shell… It makes the watch feel comfortable on your wrist for an extended period of time, despite its imposing size. The closed-back design of the SR850 helps replicate an open, natural sound profile like doing without a voice coil cover which gives wired headphones their immersive listening experience loved by true audiophiles. You can forget that you even have them on your head, with those plush ear cups and cushioned band feel like heaven during extended listening sessions.
The Wired Advantage: Quality Over Convenience
Nowadays, wired headphones seem like a rare breed in the increasingly wireless world and it can be difficult to source an appropriate device with 3.5mm connection Especially given that many new smartphones no longer support this input format at all! For this particular review, I pulled out my MacBook and streamed high-res audio files on Apple Music. The adapter is a small price to pay for great sound if your headphone jack-less device. Luckily, the HD 620s is bundled with a 6.3mm adapter which should work well if you plan on using it in headphones without an impedance problem and home music system that have regular headphone jacks only.
Audio Performance: Immersive and Balanced
Impressed in like 3 seconds when I hit play on Santana's Evil Ways. That balanced sound profile is married to an open-back headphone design in the HD 620S and it produced a sense of spaciousness from our music listening that sounded quite unlike you might expect while wearing headphones. This sense of air is not common in closed back designs, which gives the sound a bit more natural feel.
But magic truly occurred when I heard Perşembe’nin Düzleri (Canlı). The string instruments and vocals on this track were the perfect blend which showcased these headphones amazing sound stage. I even wondered for a moment if the earbuds and wireless headphones I have been using were trash due to how well-balanced that audio sounded! It's not simply that the HD 620S sound great; they escape from your head completely.
Creating a Personal Soundspace
In recent years, I’ve grown accustomed to noise-cancelling headphones that drown out the world around me. The HD 620S takes a different approach. While it doesn’t block out ambient noise, it creates a personal space where the music takes center stage. You remain aware of your surroundings, but the music is so engaging that everything else fades away. It’s like sinking into an audio bliss.
Bass and Beyond: Balanced Sound for All Genres
The HD 620S handles bass beautifully, offering depth without overwhelming the music. I tested it with some techno tracks and found the bass to be punchy but controlled. When I switched to an audiophile version of Spanish Harlem, the headphones continued to impress, solidifying their place among the best I’ve ever used.
A Worthy Investment for Music Lovers
Priced at ₹32,990, the Sennheiser HD 620S is an investment in your love for music. These headphones are built to last, and their superior sound quality will likely lead you to explore even higher-quality music sources. Over time, the cost of ownership becomes more justifiable, especially when you consider how long these headphones will serve you.
For me, the HD 620S has sparked a reevaluation of my audio preferences. After years of relying on wireless earbuds, I’m ready to return to the purity of wired sound, enjoying music the way it was meant to be heard.
