If you want wireless TV listening for study breaks and the freedom to move around, choose Retekess TA005; if you need wired, studio-style headphones for focused study listening, choose Linsoul Kiwi Ears Division.
For study, the deciding difference is simple: the TA005 is built around a transmitter and TV connections, while the Division is a wired pair tuned for music monitoring. Neither is an open-ear design, and neither is specifically described as a sleep or call headset.
• Retekess TA005: Its biggest strength is wireless TV listening with a stated range of up to 100 feet and support for optical, AUX, and RCA audio outputs. Its trade-off is that it depends on a transmitter and a compatible TV output.
• Linsoul Kiwi Ears Division: Its biggest strength is a wired, over-ear design with a 40 mm dynamic driver and a sound profile aimed at monitoring. Its trade-off is that the cable ties you to your playback device.
• Choose the TA005 if you want to listen to a compatible TV while moving around the room or keeping TV audio separate from the speakers.
• Choose the Division if your study routine centers on music, a wired connection, and a headphone sound profile designed for listening to instruments and vocals.
The Retekess TA005 is a wireless TV headphone system, not simply a conventional set of headphones. A transmitter connects to a TV’s optical, AUX, or RCA audio output, then sends sound to the over-ear headphones. The listed range is up to 100 feet, which may suit someone who wants to move around a home without being tethered to the television. Its stated battery life is 10 hours, with a three-hour charge time.
That setup could be useful for study when a television is playing a lecture, educational program, or other relevant audio and you want to listen privately. The product description emphasizes synchronized audio and reduced delay, a practical consideration when following spoken material or watching a speaker on screen. It also has two transmitter channels, with the stated option to use two transmitters in the same room.

Linsoul Kiwi Ears Division: Who It's For
The Linsoul Kiwi Ears Division is a wired, over-ear headphone made with music monitoring and DJ use in mind. Its 40 mm dynamic driver and stated frequency range of 20 Hz to 20 kHz give it a clearly defined music-listening role. The tuning is described as bass-forward in impact, neutral through the midrange, and clear in the treble. That balance may appeal to a student who studies with music and wants vocals and instruments to remain easy to distinguish.
The Division connects by cable and includes 3.5 mm and 6.35 mm connectivity, according to its product details. That makes it a more direct fit for compatible audio sources and equipment than the TA005’s TV transmitter arrangement. It is also described as lightweight, with vegan-leather wrapping on the headband and ear cushions. Passive noise cancellation is listed, though no degree of noise reduction is specified.
• Best for wireless TV listening → Retekess TA005. Its transmitter is made to connect to a TV’s optical, AUX, or RCA audio output.
• Best for moving around while listening to TV → Retekess TA005. Its stated wireless range reaches up to 100 feet, though actual use depends on the setup and surroundings.
• Best for wired study listening → Linsoul Kiwi Ears Division. Its cable-based design suits a compatible device or audio setup without requiring the TA005 transmitter.
• Best for a music-monitoring sound profile → Linsoul Kiwi Ears Division. It is described with strong bass impact, a neutral midrange, and clear treble for music and studio use.
• Best for TV audio synchronization → Retekess TA005. Its design emphasizes low delay and synchronized sound, which can matter when watching a speaker or following a program.
• Best if you want to avoid a transmitter setup → Linsoul Kiwi Ears Division. It is wired, so there is no separate wireless TV transmitter to connect.
• Best for a longer stated listening window between charges → Retekess TA005. Its battery life is listed as 10 hours; the Division is wired and has no battery figures listed.
• Best for crystal clear calls in ear earbuds for study → neither, based on the listed details. These are both over-ear headphones, and neither product information specifies a microphone or call-focused features.
• Best for open ear earbuds for study → neither. Both products are over-ear, so shoppers seeking an open-ear fit should look at a different category.
• Best for sweatproof sleep headphones for study → neither is established by the available product details. Neither is described as sweatproof or designed for sleep.
My Verdict
In my opinion, I’d choose the Linsoul Kiwi Ears Division for study if my main activity were listening to music through a compatible device: its wired connection and monitoring-oriented tuning make its purpose straightforward.
For study with music, the Division is the more direct fit: it is wired and tuned for monitoring-style listening. For a TV-based lecture or program, the TA005 is designed for wireless TV audio and emphasizes low delay.
It supports TVs with optical, AUX, or RCA audio output ports. A coaxial output is not supported without an additional converter, and some TVs may need their audio output configured to a compatible format such as PCM or stereo.
No wireless connection is listed. The Division is wired and includes 3.5 mm and 6.35 mm connectivity, so check that your playback device or setup accepts the relevant connection.
The listed details do not specify a microphone, sleep-focused construction, or sweatproof protection for either product. Both are over-ear headphones, so neither should be treated as an in-ear call headset, an open-ear design, or a verified sweatproof sleep option.
