Last month, Sennheiser introduced the HD 620S headphones to the Indian market. The audio gadget has a closed-back, over-the-ear style. The headphones bear a striking resemblance to their HD 600 series. It also features 38mm diaphragms and a 42mm dynamic transducer. Furthermore, they have a nominal impedance of 150 Ohms and a frequency response range of 6 Hz to 30,000 Hz. The sound is expected to be highly airy and open with its closed-back design. The device cost Rs 32,990 when it was first released in India. At this price, are they worth purchasing? After using it for a few days, here’s our review of the Sennheiser HD 620S.

Sennheiser HD 620S Review: Design
A typical cardboard box was sent to us, and we opened it to discover what was inside. A drawstring bag containing the headphones and a stock cable is located within the box. Only a manual and a cable tie were among the few other accessories that we saw.
When considering a new headphone purchase, the sound quality is the primary consideration, followed by comfort in second place and design in third. First, let’s talk about the design. The gadget was sent to us in the black colour variant for review, and this is the only colour option. We have to say, they have a good weight.
While the headphones may be basic in their design, their aesthetic appeal persists. If you choose minimalist device designs over flashier ones, then you might enjoy these. This style of earcups and headband hasn’t been seen in a while.

Soft cushioning and deeper earcups are features of the Sennheiser HD 620S. An even greater visual is provided by the angled drivers within. The earcups swivel a little bit, but they don’t lay flat.
To determine how comfy they were, we first tried them on. The memory foam cushioning inside the PU leatherette earcups is what gives them their structure. These may be utilised for extended periods due to the earcups’ plush padding. On the upper inside portion of the rim area, there is also additional padding. The padding is sweat-resistant, too. Those who use glasses may find the HD 620S uncomfortable for prolonged use, which is especially problematic.
The headphones’ metallic extenders allow you to adjust the device; however, the majority of the device’s body is composed of plastic with a matte finish. The metal extenders remain mostly concealed below the headphones’ headband and are only noticeable when you make certain adjustments.
The headband with metal bracing maintains a firm hold on your head, preventing it from slipping over time. However, in our case, even the smallest head movement would cause them to fall off. Not even with the tightest grip could it stay on. We believe a person with a larger head size would find it to fit nicely. If they don’t fit right, you can also lengthen the rim, but they fell off our small head when we moved around.
Although the HD 620s offer less breathability, they do offer good isolation. Consequently, you will likely feel a little more uncomfortable/claustrophobic in these if the room is heated or you build up a lot of heat.
Large earcups give the headphones a weighty appearance. How we wish these could be folded inwards. If they had that capability, they could have been carried around more easily than they are now. Even though they aren’t foldable, we can at least expect a travel hard case for the price it comes in.
In the box, you also get a 1.8-meter detachable cable with a 3.5mm plug and a 3.5mm to 6.3mm adapter to support most of the available mobile devices, laptops, and speakers. Interested users can get an optional 4.4mm cable for pairing with hi-fi devices.
Sennheiser HD 620S Review: Performance
The Sennheiser HD 620S has 42mm dynamic transducers with a 38mm diaphragm that have been specially tuned. With a 150-ohm aluminium voice coil, the headphones’ closed-back construction is supposed to enhance the audio quality. With a nominal impedance of 150 Ohm, they provide a frequency response range of 6 Hz to 30,000 Hz. The sound pressure level of the over-the-ear headphones is 110 dB.
The Sennheiser HD 620S lacks several latest features, such as touch controls and ANC, just like a lot of other wired headphones. Which in the price bracket, we feel are a must as makers like Sony are giving them.
When it comes to sound quality, we must listen to familiar music to assess the sound quality. Some of the tracks we heard on these headphones were “Same Old Love” by Selena Gomez, “How Do You Sleep?” by Sam Smith, and “Do Lafzon ki hai Dil ki Kahani” by Asha Bhosle.
Finding spots where the sound is better, different, or less bright was easy for us to do quickly. Listening to these tracks while at work or at night sounded soothing. It truly depends on the record you are listening to, but we generally want something a little warmer during that period. On these headphones, for example, Half Moon Run’s “Full Circle” sounded amazing.

It doesn’t have any punch; it sounds predominantly warm. This is acceptable, but the HD 620S falls short of what is expected of closed-back headphones, which are meant to fully use their sealed environment and provide heavier bass with greater impact than open-back headphones.
If you are a bass-head, we wouldn’t suggest these headphones, even with their decent bass quality. In our opinion, the female vocals and instruments lacked the fire and richness of sudden strikes in the piano, drums, or guitars. While it may sound accurate and nice to many, we didn’t find it all that great considering the money one will pay for these. For a more relaxed listening experience, this is a fantastic addition. Since many of the songs we listen to are bass and mid-heavy, how we wish we could also have a rich, exciting, and explosive sound experience.
Voice assistant support, ANC, and touch controls were a few other features we were missing; perhaps we expect them to be included in the next iteration.
Verdict
The Sennheiser HD 620S comes with earcup housings and a headband reinforced with metal. One thing that we did notice might be uncomfortable for some people. When the user bends their head forward or backwards, the headphones have a propensity to slide a little. The device’s grip could be improved. Although most people’s ears can accommodate Sennheisers, if your head is very huge, the device will simply fit you better.
It sounds better than most even without instrument separation and soft edges around instruments; you just get a more comfortable listening experience. We think the company decided against going with a dynamic and explosive sound in favour of a soothing, uninterrupted music performance.
It is a great option if you enjoy listening to music at ease with headphones, but in the end, personal preferences will determine which is the ideal option. We believe that fans of old-school rock will likely enjoy this one slightly less. In terms of closed-back sound quality, we would rate this headset as good—not fantastic, but not terrible either.
