If you want comfortable, wired sound for TV watching, choose Sennheiser HD 599; if you need wireless listening with active noise cancelling, choose Technics Hi-Res. For a living-room setup, the HD 599’s two detachable cables make its wired connection straightforward, while the Technics adds Bluetooth and adjustable noise control for listening in noisier surroundings.
Sennheiser HD 599 vs Technics Hi-Res at a Glance
• Sennheiser HD 599 strength: Open-back design and padded, velour-covered earcups for a spacious presentation and long listening sessions. Trade-off: It is wired and does not have noise control.
• Technics Hi-Res strength: Bluetooth, three active noise-cancelling modes, and ambient sound enhancement. Trade-off: It is a more feature-focused wireless choice, rather than an open-back wired design.
• Sennheiser HD 599 is for: Home listeners who want a wired over-ear headphone with two cable options and a comfort-oriented fit.
• Technics Hi-Res is for: Listeners who want wireless playback, active noise cancelling, and a way to let surrounding sound in when needed.
• For TV watching: Choose based on your setup: the Sennheiser includes a long cable with a 6.3 mm jack, while the Technics offers Bluetooth and also includes a detachable audio cord.
The HD 599 is an around-ear, open-back wired headphone. Its central appeal is a roomy, natural listening presentation paired with large velour ear cushions and a padded headband. Sennheiser also specifies transducers with aluminum voice coils, designed for high efficiency, dynamic response, and low distortion. Those details make it a considered option for music and home listening, not a compact or wireless one.

The padded headband and velour-covered ear pads are aimed at extended wear, but the HD 599 is described for adults, not as a children’s headset. I would consider it for an adult who prioritizes an open presentation, cable options, and comfort-focused design. I would skip it if you need Bluetooth, active noise cancelling, or sound isolation: its open-back construction and lack of noise control do not match those needs.
The Technics Hi-Res is an over-ear Bluetooth headphone with 40 mm dynamic drivers and active noise cancelling. Its three-mode selector is intended to adjust noise reduction for different surroundings. A touch feature on the right earcup enhances ambient sound, which can be useful when you want to hear nearby announcements or traffic without treating the headphones as fully isolating.
For TV watching, Bluetooth may appeal if your television supports a compatible connection, but the product information does not specify TV compatibility or promise a particular wireless delay. It also comes with a detachable audio cord, giving you a wired option when the setup calls for one. The included USB charging cord supports charging, but these are not in-ear headphones: the search phrase “USB C charging in ear headphones for tv watching” describes a different kind of product, and the listed information does not identify the charging connector as USB-C.
This is the more natural fit for someone who wants wireless listening and noise control beyond the living room. Technics lists Bluetooth 4.2 and support for LDAC and apt-X HD, alongside a playback pause sensor that stops music when the headphones are removed and resumes it when they are put back on. I would skip this model if your priority is an explicitly open-back design or a long included cable for a home system. The supplied audio cord is listed as 3.9 feet, much shorter than the Sennheiser’s 3-meter cable.
Side-by-Side: Which Should You Choose?
• Best fit for wired TV listening → Sennheiser HD 599. Its 3-meter cable and 6.3 mm jack are geared toward a home entertainment connection, assuming your equipment has a compatible output.
• Best for an open-back listening presentation → Sennheiser HD 599. The open-back design is its defining distinction; it does not provide active noise cancelling.
• Best for adjustable noise reduction → Technics Hi-Res. Its three ANC modes are intended for different levels of surrounding noise.
• Best for hearing some surroundings on demand → Technics Hi-Res. Touching the right earcup activates ambient sound enhancement.
• Best for multiple included wired connections → Sennheiser HD 599. It comes with detachable 3-meter and 1.2-meter cables with different jack sizes.
• Best for automatic pause behavior → Technics Hi-Res. Its sensor pauses playback when the headphones come off and resumes when they are put back on.
• Best ear clip headphones for TV watching → Neither. Both are over-ear designs, so someone specifically seeking ear clips should compare a different style rather than treating either of these as a match.
One distinction worth keeping clear: noise cancelling is not the same as an open-back sound. The Technics is built to reduce external noise, while the Sennheiser’s open-back construction emphasizes a more open spatial presentation. For a shared room, either choice has practical limitations: the Technics’ features do not guarantee that you will hear every sound around you, and the Sennheiser’s open-back design is not intended to block the environment.
I’d choose the Sennheiser HD 599 for TV watching if my setup supports its wired connection. The longer cable, two detachable cable options, open-back design, and velour-covered ear pads make it the more convincing home-listening pick for me. I’d choose the Technics instead when wireless playback and active noise cancelling matter more than an open-back presentation.
No. Both are over-ear headphones, with earcups that fit around the ears. Neither is an earbud or an ear-clip design.
For a compatible wired home setup, the HD 599’s 3-meter cable and 6.3 mm jack are a practical advantage. The Technics offers Bluetooth and a detachable audio cord, but check that your TV supports the connection you plan to use.
Yes. It has hybrid active noise cancelling with a three-mode selector. It also offers ambient sound enhancement through a touch control on the right earcup.
The HD 599 is specifically described with a padded headband and velour-covered ear cushions for extended listening. The Technics is also described as comfortable, with ear pads that move on a ball joint, but the available product details do not establish a direct comfort winner.
