If you want an open, wired listening setup for a TV connected to a suitable headphone output, choose beyerdynamic DT 990; if you need wireless convenience, noise cancellation, and long battery life, choose Sennheiser Consumer Audio Momentum. For TV watching, the key difference is straightforward: the DT 990 is built around open-back listening, while the Momentum 4 adds Bluetooth, adaptive noise cancellation, and up to 60 hours of battery life.
beyerdynamic DT 990 vs Sennheiser Consumer Audio Momentum at a Glance
• beyerdynamic DT 990 strength: Open-back construction and a wide, natural soundstage for a more spacious listening presentation. Trade-off: It is wired, has no noise control, and its 250-ohm impedance suits a capable headphone output.
• Sennheiser Consumer Audio Momentum strength: Bluetooth, adaptive noise cancellation, transparency mode, and up to 60 hours of battery life. Trade-off: It relies on a battery for wireless use and uses closed-back over-ear design rather than the DT 990’s open-back approach.
• For TV watching with a suitable wired audio source: Choose the DT 990 if open-back listening matters more than wireless convenience.
• For a flexible wireless setup: Choose the Momentum 4 if Bluetooth, noise control, and app-based sound adjustment matter more.
• Who each pick is for: DT 990 suits listeners with a compatible headphone output; Momentum 4 suits listeners who want wireless headphones that can also handle travel, calls, and everyday listening.
The DT 990 is an over-ear, open-back headphone designed for wired listening. Its stated frequency range is 5 Hz–35,000 Hz, and beyerdynamic describes its soundstage as wide and natural. For TV, that design may appeal if you want a more open presentation while listening from a source with a suitable headphone output.

The important practical detail is its 250-ohm impedance. The product is positioned for studio interfaces, dedicated headphone amplifiers, home hi-fi equipment, and audiophile systems. That makes the audio connection worth checking before you choose it for a television: the headphone itself is wired, with 3.5 mm and 6.35 mm jack connections listed, but the TV or audio system must provide a compatible output.
The DT 990 has soft, circumaural, replaceable ear pads and weighs 1.2 pounds. Its open-back design offers no noise control, so it is a poor match if you need to block household sounds or keep your audio contained around other people. I’d skip it for a simple, cable-free setup or a TV whose headphone output is not suited to a 250-ohm headphone. Its strongest fit is a listener who already has the right wired equipment and prefers the open-back approach.
The Momentum 4 is an over-ear Bluetooth headphone with adaptive noise cancellation and a transparency mode. Its 42 mm transducers, app-based equalizer and sound modes, and aptX Adaptive support give you more ways to tailor wireless listening than the DT 990 offers. For TV watching, Bluetooth is convenient if your TV or an attached device can transmit compatible Bluetooth audio; confirm that connection path before buying.
Its listed battery life is up to 60 hours. The headphones also fold, come with a carrying case, and include a USB-C charging cable and a 3.5 mm-to-2.5 mm audio cable. That combination makes them more adaptable to travel and everyday use than a purely wired model, though Bluetooth listening still depends on keeping the headphones charged.
For calls, Sennheiser lists four digital beamforming microphones, along with wind-noise suppression and voice-assistant access. Those are useful extras if you want one headphone for TV, music, commuting, and calls. The trade-off is that it is not an open-back design: listeners specifically drawn to the DT 990’s open presentation should not assume the Momentum 4 provides the same experience. I’d choose it when wireless flexibility and noise-control options matter more than open-back listening.

The phrase “best sports earbuds for TV watching” describes a different category from either of these products. Both models are over-ear headphones, not earbuds. Likewise, neither is an open-ear headphone, and the provided details do not describe either as a spatial-audio headband. If those specific formats are your priority, these two are not direct matches.
For TV watching, I’d choose the beyerdynamic DT 990 if I had a compatible headphone output and wanted the open-back presentation. Its wired, 250-ohm design makes the source connection a real consideration, not a minor detail.
If I wanted one headphone for wireless TV listening, travel, and calls, I’d choose the Sennheiser Consumer Audio Momentum instead. My overall recommendation is the DT 990 for a properly equipped home setup; the Momentum 4 is the more flexible choice when convenience leads.
The DT 990 fits a wired TV or audio setup with a suitable headphone output. The Momentum 4 fits a compatible Bluetooth setup and offers adaptive noise cancellation and transparency mode. Check your TV’s connection options before deciding.
The listed 250-ohm impedance is intended for sources such as dedicated headphone amplifiers, studio interfaces, and home hi-fi equipment. Whether a particular TV can drive it appropriately depends on that TV’s headphone output.
It includes adaptive noise cancellation and a transparency mode. The DT 990 has no noise-control feature, and its open-back construction is a different design intended for open listening rather than isolating sound.
The Momentum 4 is wireless, foldable, includes a carry case, and has up to 60 hours of stated battery life. The DT 990 is wired and is positioned more toward a home or studio setup.
