If you want open-back headphones with a relaxed, detailed sound for PC listening, choose Sennheiser HD 599; if you need wood ear cups, a detachable cable, and included connection options, choose okcsc R11. For a PC setup, I’d lean toward the Sennheiser for its stated strengths in spatial detail and everyday versatility, while the R11 makes more sense if its materials and hardware are your priorities.
Both are wired, open-back, over-ear headphones, so neither is designed to keep sound in or block outside noise. That matters at a shared desk, but it can be a plus for airy listening at home.
• Sennheiser HD 599: Its open design is described as delivering a wide, relaxed soundstage suited to music, work, and gaming; the trade-off is that the open construction does not isolate you from your surroundings.
• okcsc R11: Solid wood ear cups, a detachable dual 3.5 mm cable, and an included adapter give it distinctive physical features; it also needs basic wood care.
• Sennheiser HD 599: A straightforward fit for someone who wants one wired pair for a computer and other compatible devices.
• okcsc R11: A better match for someone who wants wood construction, adjustable metal hardware, and cable flexibility.
• Who should choose which? Pick the HD 599 for a versatile, spacious listening experience; pick the R11 if the wood cups and detachable-cable setup matter more to you.
The HD 599 is an open, wired over-ear headphone built around a spacious listening presentation. Its description emphasizes relaxed, detailed sound and clear spatial placement, with music, voices, instruments, and in-game cues all part of the intended use. For PC listening, that makes it an appealing option for someone who moves between music, work calls or media, and games rather than buying a headset for one narrow task.
It is also described as compatible with computers, phones, tablets, and most audio devices. That versatility is useful if you want a wired pair that can move between a desktop and other listening setups. Sennheiser also highlights its materials and durable design, though the available product information does not specify construction details beyond that general description.
I’d skip it if your main need is sound isolation or a closed-back fit. The open design is meant to create a natural, spacious presentation, not to shut out a busy room. It is also not the pick for someone who specifically wants wood ear cups, a detachable dual-plug cable, or a supplied adapter and storage case; those are stated R11 features, not HD 599 features.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
The R11 is an open-back wired headphone with solid wood ear cups and a 53 mm dynamic driver. Its listed frequency response is 18 Hz to 25 kHz, and its impedance is 32 ohms. Those figures give a buyer useful technical context, but they don’t establish how it will sound to any individual listener. The product description presents it as suited to music listening, home audio, and studio-oriented use.
The physical setup is one of its clearest distinctions. It includes a 1.5-meter detachable cable with dual 3.5 mm plugs, plus an adapter, ear cushions, and a protective case. Protein-leather earmuffs and an adjustable metal lever are also listed. For a PC desk, the detachable cable may be welcome if you prefer a cable that can be removed from the headphones for storage or handling.
The R11 has some practical obligations, too. Its wooden ear cups need protection from direct sunlight and prolonged moisture, and the product information recommends periodic olive-oil care. I’d pass if you want a low-maintenance pair or need noise control: the R11 is open-back and lists no noise control. Its described design also makes it a wired listening headphone, not a substitute for a wireless or microphone-equipped gaming headset.
• Best for a versatile PC-and-device setup → Sennheiser HD 599. Its stated compatibility includes computers, phones, tablets, and most audio devices.
• Best if you want solid wood ear cups → okcsc R11. The wood construction is a defining part of its design, but it calls for basic care.
• Best for a detachable cable → okcsc R11. Its included 1.5-meter cable detaches and uses dual 3.5 mm plugs.
• Best for an open, spacious gaming presentation → Sennheiser HD 599. Its product description specifically points to spatial representation that helps keep game cues clear.
• Best if you want an included adapter and protective case → okcsc R11. Both are listed among the supplied items.
• Best for low-maintenance ownership → Sennheiser HD 599, by the information provided. The R11’s wood-care guidance adds a task that the HD 599 information does not mention.
• Best for blocking room noise → Neither. Both are open-back designs, and the R11 explicitly lists no noise control.
• Best for a PC gaming headset with a mic → Neither based on the listed features. The provided information does not specify a microphone for either model.
A search for “hifi stereo gaming headphones for pc” often points shoppers toward soundstage and positional clarity. The HD 599’s description speaks directly to that use, but neither model’s listed details establish microphone support or game-chat controls. If you need those, treat these as listening headphones and check for a separate microphone solution.
My Verdict
In my opinion, I’d choose the Sennheiser HD 599 for PC use because its stated strengths line up with a broad mix of music, work, and gaming, and it is described as compatible with computers and other devices. The okcsc R11 has the more distinctive materials and a useful detachable-cable package, but its wood-care requirements make it a more particular choice. For an everyday wired PC listening pair, I’d take the HD 599.
Both are wired, over-ear, open-back headphones, and the HD 599 is specifically listed as compatible with computers. The R11 lists desktops and laptops among compatible devices and includes a 3.5 mm cable setup.
The HD 599 is the clearer fit from the stated information because its description highlights spatial representation and audible in-game cues. Neither product sheet lists a microphone, so don’t assume either is a complete voice-chat headset.
Neither is presented as a noise-isolating option. The HD 599 and R11 are open-back designs, and the R11 explicitly lists no noise control.
The HD 599 is described as using quality materials and being designed for durability, without a specific care routine listed. The R11 has solid wood ear cups that should be kept away from direct sunlight and prolonged moisture, with periodic olive-oil care recommended.
