If you want closed-back isolation and a more contained listening space for your computer, choose Sennheiser HD 620S; if you need an open-back planar design with a wide lateral soundstage, choose FiiO FT1.
That’s the main dividing line. The HD 620S is the more focused fit for a desk where you want to limit distractions, while the FT1 Pro is built around an open presentation and planar drivers. Both are wired, over-ear headphones with a 3.5 mm connection, but they serve different listening environments.
• Sennheiser HD 620S strength: Closed-back isolation paired with angled 42 mm dynamic drivers; trade-off: its 150-ohm impedance makes it a more demanding match than the FT1 Pro’s listed 20 ohms.
• FiiO FT1 Pro strength: A planar magnetic driver and open-back design aimed at a wide soundstage; trade-off: it has no noise control, so it is less suited to blocking nearby sounds.
• HD 620S connection: Wired 3.5 mm cable, with a 6.3 mm adapter included.
• FT1 Pro connection: Wired 3.5 mm jack, with volume control listed.
• Choose the HD 620S if you want a more private, distraction-conscious setup for work, music, or gaming.
• Choose the FT1 Pro if you mainly listen in a quiet room and want an open-back planar headphone.
The HD 620S is the clearer choice for someone who wants over-ear headphones that help create a more secluded listening space. Its closed-back design provides sound isolation, while Sennheiser’s open-baffle approach is intended to preserve a spacious, natural character. That combination makes it an interesting option for a home desk: you can reduce some surrounding distractions without choosing a design focused solely on a sealed-in sound.
Its 42 mm dynamic drivers use 38 mm diaphragms and are angled to support stereo imaging. That gives the HD 620S a useful case for computer gaming and multimedia, where locating sounds across a stereo field matters. The headphones are also positioned for music and everyday listening, with a detachable 1.8 m cable and a 3.5 mm-to-6.3 mm adapter for compatible desktop or audio equipment.

FiiO FT1: Who It's For
The FiiO FT1 Pro takes the opposite approach. It is an open-back, wired over-ear headphone with a planar magnetic driver, rather than a closed-back dynamic model. FiiO describes its 95 × 86 mm flat unit as designed for a broad lateral soundstage, and lists a frequency range of 20 Hz to 40 kHz. Those are the most relevant features for listeners drawn to an open presentation and planar-driver design.
The FT1 Pro makes the most sense for a quiet home or studio space where you are not relying on the headphones to keep nearby sound out. It may suit music listening at a computer when your surroundings are calm and you want the design and driver type to be central to the choice. Its listed impedance is 20 ohms, and it uses a 3.5 mm jack. Volume control is also listed.
The trade-off is straightforward: the FT1 Pro has no noise control, so it is not the better pick for a noisy shared workspace or a room where you need isolation. Its open-back design also makes it a less natural fit for someone looking for closed-back privacy. The product information lists its weight at about 374 g, another practical detail to weigh if you are choosing headphones for long stretches at a computer.
• Best for a more isolated computer setup → Sennheiser HD 620S. Its closed-back design offers sound isolation; the FT1 Pro lists no noise control.
• Best for a quiet room and an open-back design → FiiO FT1 Pro. Its open construction is central to its wide-lateral-soundstage design.
• Best fit for gaming headphones for computer → Sennheiser HD 620S. Its angled dynamic drivers are designed to support stereo imaging, and the closed-back build helps limit distractions.
• Best fit if planar magnetic drivers are your priority → FiiO FT1 Pro. It uses a planar magnetic driver rather than the HD 620S’s dynamic driver.
• Best for a 6.3 mm audio connection option → Sennheiser HD 620S. It includes a 3.5 mm-to-6.3 mm adapter alongside its detachable 1.8 m cable.
• Best for the lower listed impedance → FiiO FT1 Pro. Its listed 20 ohms compare with 150 ohms for the HD 620S; actual suitability still depends on your audio source.
• Best for someone who wants no noise-control feature → FiiO FT1 Pro. It lists no noise control, while the HD 620S is specified with sound isolation.
• Best for combining isolation with a spacious design goal → Sennheiser HD 620S. Its closed-back construction and open-baffle approach aim to balance those characteristics.
One search phrase worth clarifying is “best active noise cancelling true wireless earbuds for computer.” Neither of these headphones is a true wireless earbud, and neither is described as having active noise cancellation. They are both wired, over-ear headphones. The HD 620S offers sound isolation through its closed-back design; that is not the same thing as active noise cancellation. Likewise, neither product is an IPX7 waterproof true wireless earbud, so shoppers searching for waterproof earbuds should look at a different category.
I’d choose the Sennheiser HD 620S for my computer setup because its closed-back design, sound isolation, and angled dynamic drivers make it the more versatile fit for focused listening and gaming. The FT1 Pro is compelling if an open-back planar headphone is specifically what you want, but it gives up isolation. For a computer shared with everyday household noise, I’d rather have the HD 620S’s more contained design.
For a computer in a shared or distracting space, the HD 620S is the more suitable choice because it is closed-back and offers sound isolation. The FT1 Pro is better matched to a quiet room where its open-back design is a priority.
The product information lists no noise control for the FT1 Pro. It is an open-back wired headphone, not an active noise-cancelling model.
No. Both are wired, over-ear headphones with a 3.5 mm connection. The provided product details do not specify an IPX7 rating or waterproofing for either model.
The HD 620S has the more direct gaming case in the provided features: its angled dynamic drivers are designed for stereo imaging, and its closed-back construction helps reduce distractions. The FT1 Pro may suit a quiet-room listener who prefers an open-back planar design.
