If you want a wired, open-back reference headphone that spreads a film's score and dialogue across a genuinely wide stage, choose beyerdynamic DT 1990; if you need wireless freedom, adaptive noise cancellation and up to 60 hours of battery for tv watching anywhere in the house, choose Sennheiser M4.
beyerdynamic DT 1990 vs Sennheiser M4 at a Glance
• Biggest strength, DT 1990: A true open-back studio reference — 45 mm Tesla neodymium drivers, 5 Hz–40 kHz response, 102 dB SPL — with a wide, natural stereo image that makes movie soundtracks feel three-dimensional.
• Biggest trade-off, DT 1990: Wired only, 250 ohms, and open cups that leak sound in both directions. It wants an amplifier and a quiet room.
• Biggest strength, M4: Adaptive noise cancellation plus a transparency mode, Bluetooth 5 with aptX Adaptive, app-based EQ and sound personalization, and up to 60 hours of playback.
• Biggest trade-off, M4: It is a closed-back wireless headphone that depends on its battery and its app. It will never be the neutral reference the DT 1990 is.
• Buy the DT 1990 if you watch in one fixed seat, you can wire into a receiver or headphone amp, and you care about imaging and detail above convenience.
• Buy the M4 if you want to move around, block out the room, and treat a TV like just another Bluetooth source — with a cable in the box as a backup.
The DT 1990 is billed as an open studio reference headphone for mixing and mastering, and that origin story explains everything about how it behaves in a living room. The 45 mm Tesla drivers, the 5 Hz–40 kHz range and the open-back cup design are all aimed at one goal: a wide, dynamic stereo image with no sense of a closed-in box around your ears. For tv watching, that translates into something specific. A score sits around you instead of on top of you. Dialogue has air around it. Effects pan across the stage in a way closed headphones struggle to match.

If you have been hunting for the best open ear headphones for tv watching, and you have also been drawn to the idea of the best spatial audio headband headphones for tv watching, this is the closest thing in this comparison to either description — open cups, over-ear fit, deliberately spatial presentation. Just go in knowing the trade-offs: the open design leaks sound outward, so it is a poor choice for a shared room or a late-night apartment, and the listed 1.5-pound weight is real. It is not a headphone you forget you're wearing after four hours.
Who should skip it: commuters, travelers, anyone who wants noise cancellation, anyone who wants to walk to the kitchen mid-episode, and anyone unwilling to add an amplifier to the chain.
The M4 is the opposite philosophy executed well. Adaptive noise cancellation that adjusts to the room, a transparency mode you toggle when someone talks to you, Bluetooth 5 with aptX Adaptive, and a battery rated at up to 60 hours with a fast-charge claim of six more hours from a ten-minute top-up. A full charge takes about two hours. The Smart Control Plus app adds an equalizer, presets, sound modes and a sound personalization routine, and there is a touchpad you can switch off if you keep brushing it by accident.
For tv watching, the practical details are what sell it. The listed Bluetooth range is 10 meters, which comfortably covers a sofa, a kitchen counter and a hallway. Audio latency is listed at 20 milliseconds — low enough that most viewers won't notice lip-sync drift, and if you do, Sennheiser includes a 3.5 mm and a 2.5 mm audio cable plus an airplane adapter in the box, so you can run it passive and wired with zero wireless delay. The design is fold-flat with a padded headband and deep cushioned ear pads at 293 g, and it ships with a carry case. Adaptive noise cancellation is the piece that matters most for TV: it lets you hear quiet dialogue over a fan, traffic or an open-plan kitchen.
The trade-offs are equally clear. This is a closed-back wireless headphone, so the soundstage is naturally narrower than an open design, and it leans on its app and firmware for features rather than on pure acoustics. The warranty is listed as one year, against two for the beyerdynamic when bought from an authorized dealer. And if your TV has no Bluetooth at all, you'll need a transmitter or the included cable — the headphone can't invent a wireless connection that isn't there.
Who should skip it: anyone mixing or mastering audio, anyone who wants a headphone that works identically in ten years with no battery inside, and anyone who resents app-based setup.
Side-by-Side: Which Should You Choose?
• Best for blocking out the room → Sennheiser M4. Adaptive noise cancellation is something the DT 1990 simply doesn't have, by design.
• Best for battery life → Sennheiser M4. Up to 60 hours, plus a fast-charge top-up of six hours in ten minutes.
• Best for late-night viewing without disturbing anyone → Sennheiser M4. The DT 1990's open cups leak sound outward.
• Best for critical listening and soundtrack work → beyerdynamic DT 1990. Neutral reference tuning, two pad sets, 5 Hz–40 kHz.
• Best for moving around the house → Sennheiser M4. Bluetooth with a 10 m listed range and a fold-flat 293 g body.
• Best for tuning the sound to your taste → a tie, different tools. Two physical pad sets on the DT 1990 versus app EQ, presets and sound personalization on the M4.
• Best for easy TV hookup → Sennheiser M4, with a caveat. It needs Bluetooth or the included cable; the DT 1990 needs an amp to drive its 250 ohms properly.
• Best for long-term ownership → beyerdynamic DT 1990. Replaceable pads and headband, detachable mini-XLR cable, two-year manufacturer warranty from an authorized dealer.
For most people watching TV, I would buy the Sennheiser M4. It handles the messy reality of a living room — noise, movement, a source that may or may not be Bluetooth — and the included cable removes the lip-sync worry when wireless misbehaves. In my opinion, the DT 1990 is the better headphone for the specific job of sitting still in a quiet room and letting a film's soundtrack fill the space, and it is the one I'd choose for serious listening. But for tv watching as most households actually do it, the M4's flexibility wins.
FAQ
Not wirelessly. You would need a Bluetooth transmitter, or you can use the 3.5 mm or 2.5 mm cable included in the box and run it wired, which also eliminates the 20 ms wireless latency entirely.
The Sennheiser M4. Its closed-back cups and adaptive noise cancellation keep sound in and room noise out, while the DT 1990's open design deliberately lets sound escape in both directions.
Up to 60 hours of playback on a full charge, with roughly two hours needed for a full charge and a ten-minute top-up adding about six hours of listening.
