If you want a wired over-ear headset with a dedicated microphone for clear conversation, choose beyerdynamic 718300; if you need open-back headphones for relaxed, spacious listening, choose Sennheiser HD 599. For TV watching, the key difference is whether you want an attached mic and sound-isolating design or an open presentation that lets more of your surroundings remain audible.
• beyerdynamic 718300: Its over-ear design, wired connection, and high-quality microphone suit gaming and dialogue-heavy listening; the trade-off is that it is a headset built around a microphone rather than an open-back listening design.
• Sennheiser HD 599: Its open over-ear design and wide soundstage suit music, films, and spatial listening; the trade-off is that an open design does not isolate you from nearby sounds.
• Choose beyerdynamic 718300 if you want a headset with a microphone, volume control, and a fit designed to stay put.
• Choose Sennheiser HD 599 if you want open headphones for a more spacious, relaxed listening experience.
The beyerdynamic 718300, also called the MMX 300 Second Generation, is a wired, over-ear headset with a 3.5 mm connection and a high-quality microphone intended to make speech intelligible. That combination makes it a natural fit for gaming, video calls, and TV sessions where you may also want to talk with someone. Its volume control gives you a direct way to adjust listening without turning the headset into a wireless setup.
Its listed 32-ohm impedance and dynamic drivers describe the headphone side of the design, while the stated 5 Hz–35 kHz frequency range gives a technical snapshot of its audio coverage. Those numbers do not, by themselves, tell you how it will sound with every TV or device. The 3.5 mm wired connection is the practical detail to check first: your television or other source needs a compatible headphone output, or another suitable connection method.
The headset is described as lightweight and intended for extended wear, with higher clamping pressure to help keep it in place during long gaming sessions. That secure fit could also appeal to someone who moves around while watching or playing. The product information lists an 11.68-ounce weight. Its sound-isolation control is another point in its favor if you would rather reduce some outside distraction than hear the room freely.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Who should skip it: Skip the beyerdynamic 718300 if an open, airy listening design is your priority or you do not need a microphone; its defining strengths are headset-focused.
The Sennheiser HD 599 is a wired, open-over-ear headphone for listeners who value spacious presentation. Its open construction is described as helping keep ears cool and supporting a wide soundstage, with voices, instruments, and game cues placed clearly in the listening space. For TV watching, that suggests a more natural, roomy style of listening rather than a design focused on sealing you off from the room.
The product information emphasizes compatibility with phones, tablets, computers, and most audio devices. It is also described as suitable for home, office, travel, remote work, music listening, and gaming. That versatility makes it a plausible choice if the same headphones will move between a television and other devices, though the listed connection is wired. Check that your TV has a compatible headphone connection before choosing it.
Its central trade-off follows directly from its open design: sound can pass between the headphones and the room. That can be pleasant when you want a less enclosed feel, but it is not the direction to take if you need strong isolation from household noise or want to keep your own audio contained. The product data lists passive noise cancellation, but the open construction remains the defining design choice and should guide expectations.
Who should skip it: Skip the HD 599 if you need an attached microphone or want an enclosed, sound-isolating headset for a noisy room.

For TV watching, neither model is wireless, so your television’s connection matters. Confirm what your TV supports before buying either one. Also consider the room: if you want to remain aware of family members or hear the door, an open design may be useful. If you would rather reduce outside distraction, the beyerdynamic’s sound-isolation feature points in the opposite direction.
In my opinion, I would choose the Sennheiser HD 599 for TV watching when a relaxed, open soundstage matters more than isolation or a microphone. Its design is clearly suited to spacious listening, with broad use across music, films, and other devices. I would choose the beyerdynamic 718300 instead for gaming and conversation, where its microphone, volume control, and secure fit are more relevant. The right pick is the one whose design matches how you actually listen.
Before choosing, decide whether you want to hear the room or reduce its presence. The HD 599 is open, which supports a less enclosed listening experience but also allows more interaction with surrounding sound. The beyerdynamic 718300 lists sound isolation, so it is the more suitable direction if reducing distraction is part of your goal. Neither design is a universal answer: an open headphone can feel more natural in a quiet room, while an isolating headset can suit a space where other sounds compete with the program.
Next, think about whether you will speak through the headphones. The beyerdynamic includes a microphone, which gives it a practical advantage for multiplayer games or calls. The HD 599’s supplied details do not list a microphone, so do not choose it on the assumption that it can serve as a headset for voice chat. For ordinary TV viewing, that may not matter; for gaming with teammates, it can change the decision.
Fit and wearing style also deserve attention. The beyerdynamic is described as lightweight, with higher clamping pressure intended to keep it secure during extended gaming. That secure fit may appeal if you want the headset to stay in place, but a snug hold is not the same as the airy character of an open headphone. The Sennheiser’s open construction is described as helping ears stay cool. Consider which quality you value more during a long film or a full evening of gaming.
Finally, match the wired connection to your setup. The beyerdynamic lists a 3.5 mm jack. The HD 599 is wired and described as compatible with a range of devices, but the information provided does not specify its connector type. Check the connection available on your TV, console, or other source, and confirm any adapter needs before deciding. For a shopper searching for the best sports earbuds for TV watching, neither of these is an earbud; they are both over-ear wired headphones. Likewise, the best open ear headphones for TV watching and the best spatial audio headband headphones for TV watching are different searches: the HD 599 is open-over-ear, while the beyerdynamic is a microphone-equipped headset. Those distinctions matter more than broad labels.
