If you want open-back listening and broad compatibility, choose Sennheiser HD 599; if you need a semi-open design with a planar magnetic driver, choose Amazon Renewed Fostex T50RP. For jogging, neither is an obvious first pick: both are wired over-ear headphones, and the Sennheiser’s open design is especially suited to quieter settings.
Sennheiser HD 599 vs Amazon Renewed Fostex T50RP at a Glance
• Sennheiser HD 599: Open over-ear design and a wide soundstage; trade-off: its open construction is not geared toward keeping sound isolated.
• Amazon Renewed Fostex T50RP: Semi-open design, planar magnetic driver, and a 4-pole 3.5 mm connector that supports balanced connections; trade-off: the supplied information does not establish broad device compatibility.
• HD 599 is for listeners who want an open, airy style for music, games, or work in a relatively calm environment.
• T50RP is for listeners drawn to planar magnetic technology and a semi-open headphone with a wired connection.
• For jogging: neither is specifically described as a sports headphone, and neither offers a wireless connection in the supplied specifications.
The HD 599 is an open, over-ear wired headphone built around a dynamic driver. Its defining feature is the open construction: rather than enclosing the ear in a closed-back shell, it is designed to create a broad soundstage and a relaxed, detailed listening experience. That makes it a natural fit for listening at home, working in an office, or playing games where a sense of space and clearly placed voices or in-game cues matter.
Its stated compatibility is a practical advantage. It is described as working with phones, tablets, computers, and most audio devices, so it can serve as a single wired headset across several everyday setups. The product information also points to music listening, remote or hybrid work, gaming, and mixing as use cases. The open design is described as helping the ears stay cool, which may appeal during longer listening sessions. Its passive noise control, however, is not a promise of strong isolation; an open design is better considered for spaces where some sound leakage and outside noise are acceptable.
The HD 599 is the more straightforward choice if you want a familiar wired headphone for varied devices and value spacious, natural-sounding presentation over isolation. Its listed weight is 0.61 kg, so I would not choose it specifically for jogging based on the available details. It also has no stated wireless connection or sport-focused feature. That does not make it unsuitable for ordinary movement around the house, but it does make it a less convincing option for a run.

The T50RP is a wired, semi-open headphone with a redesigned RP planar magnetic driver. That driver technology is its clearest distinction from the HD 599’s dynamic driver. If you are specifically comparing driver designs or want to explore a planar magnetic model, the Fostex gives you a concrete reason to consider it. Its semi-open enclosure also places it between the fully open style associated with the Sennheiser and a closed-back design, though the supplied information does not quantify how much sound it blocks or leaks.
The connector is a 4-pole 3.5 mm type and is described as supporting balanced connections. That gives the T50RP potential flexibility in a compatible wired setup, but a balanced connection is only useful if the rest of the audio equipment supports it. The cable is specified as using OFC conductors. The thicker, low-resilience, around-ear pads are intended to make extended listening more comfortable, which is relevant if you plan to use the headphones for longer stretches at a desk or during focused listening.
There are limits to what can be concluded from the listed details. The T50RP is described as wired, and the product information identifies a cable as its built-in media; it does not establish a wireless operating mode. Its weight is listed as 0.52 kg. The supplied specifications also do not give a broad compatibility statement like the one provided for the HD 599, so check that the intended source and any balanced connection match your setup. As an Amazon Renewed listing with a stated 90-day limited warranty, it also has a different purchase context from a standard new-product description.
Who should skip it: Skip the T50RP if you specifically need a wireless headset for running or want clearly documented compatibility across phones, tablets, and computers.
• Best for a wide, open presentation → Sennheiser HD 599. Its open over-ear design is described as producing a broad soundstage and a relaxed, detailed listening experience.
• Best if planar magnetic technology matters to you → Amazon Renewed Fostex T50RP. Its redesigned RP planar magnetic driver is the defining hardware difference.
• Best for stated device versatility → Sennheiser HD 599. Its listed compatibility includes phones, tablets, computers, and most audio devices.
• Best for a balanced wired setup → Amazon Renewed Fostex T50RP. Its 4-pole 3.5 mm connector supports balanced connections when paired with compatible equipment.
• Best for long listening sessions where around-ear padding is a priority → Amazon Renewed Fostex T50RP. Its thicker, low-resilience pads are described as an around-ear style intended for comfort over extended use.
• Best for gaming or work where spatial cues matter → Sennheiser HD 599. Its product description calls out precise spatial representation for voices, instruments, and game clues.
• Best for jogging → neither is a clear match. Both are wired over-ear models, and the supplied details do not describe a sports fit or wireless operation.
• Best if you want a stated 90-day limited warranty → Amazon Renewed Fostex T50RP. That warranty is listed for the Renewed product; compare the terms relevant to your purchase before deciding.
In my opinion, I would choose the Sennheiser HD 599 for everyday listening across devices, especially for music, games, and work in a quiet setting. Its open presentation and stated compatibility make its role easier to understand.
For jogging, I would choose neither as my first option: both are wired over-ear headphones, and the available specifications do not establish a jogging-focused design. If I had to pick between these two for a desk setup, I would take the HD 599 for versatility; I would choose the T50RP instead if planar magnetic technology and balanced connectivity were the deciding priorities.
Before choosing, think about where you will listen and what equipment you already own. An open or semi-open construction is not the same as a closed headphone designed around isolation. The HD 599 is explicitly open, while the T50RP is semi-open. Neither specification establishes how much sound will reach people nearby or how much outside noise you will hear, so these are better candidates for settings where that is not a major concern.
Next, check the source connection. Both models are wired, but the T50RP’s 4-pole 3.5 mm connector has a particular benefit only when the audio source and cable arrangement support balanced connections. The HD 599 has the clearer stated compatibility range, covering phones, tablets, computers, and most audio devices. If your main goal is a simple headset for jogging, the supplied facts do not identify either one as a sports model, and neither is described as wireless. Shoppers seeking the best ANC headphone for jogging should note that neither product is listed with active noise cancellation; the HD 599’s stated noise control is passive. Likewise, someone searching for a foldable kids headset for jogging or earbuds for jogging is looking for a different kind of product than either of these over-ear headphones.
Finally, consider the wearing experience and intended session length. The HD 599’s open design is described as helping ears stay cool, and the T50RP’s thicker around-ear pads are described as supporting comfort during longer listening. Those are different design considerations, not a direct guarantee that one will feel better on every listener. For a purchase decision, check the current price on Amazon using the page’s button, and review the product and warranty details there before ordering.
Neither is specifically described as a jogging headphone. Both are wired over-ear models, and the available details do not establish a sports fit or wireless operation. I would choose a purpose-designed sports option if running is the main use.
