If you want a featherweight, all-day wearable for music and travel that prioritizes pure comfort and portability, choose RETRADEKING Headphones Over Ear; if you need a dedicated home theater system with long-range RF transmission, zero-latency syncing, and the ability to share audio with a soundbar, choose SIMOLIO TV Headphones.
• RETRADEKING Headphones Over Ear: Its greatest strength is an ultra-light 137g build with memory protein foam designed for extended wear, but it trades off specialized TV latency handling in favor of general Bluetooth versatility.
• SIMOLIO TV Headphones: It offers a massive 20-hour battery life and a unique "bypass" feature for simultaneous soundbar use, yet it is significantly heavier at 1.7 pounds and requires a dedicated transmitter setup.
• Who this is for: RETRADEKING is ideal for travelers and commuters who need a discreet, comfortable companion for planes and trains, while SIMOLIO is built specifically for the living room couch and seniors needing volume control.
The RETRADEKING headset is engineered with a singular focus on weight reduction and physical comfort, making it a standout choice for anyone who wears headphones for long stretches without wanting the pressure of heavy plastic or metal frames. Weighing in at just 137 grams, or roughly 0.3 pounds, this is one of the lightest wireless headsets available on the market. The earcups utilize soft memory protein foam, which molds gently to your ears, and the adjustable headband ensures a secure fit without clamping down too tightly. This design philosophy makes it particularly suitable for people who find standard over-ear models too heavy or hot during long sessions.
In terms of connectivity, this unit shines as a versatile bridge between various devices rather than a dedicated TV dongle. It features Bluetooth 5.3 technology, which provides a stable connection up to 10–15 meters (roughly 33–49 feet) from your source. While it includes a USB transmitter for connecting to PCs or TVs via a 3.5mm or RCA cable, its primary strength lies in its ability to pair directly with smartphones, tablets, and computers wirelessly. The inclusion of a built-in microphone allows for hands-free calling, adding a layer of utility for those who need to take calls while listening to music or watching content.

However, this product is not a magic bullet for every scenario. If you are looking for a device specifically optimized for low-latency video synchronization on non-Bluetooth TVs, you might find the standard Bluetooth connection introduces a slight delay depending on your source device. Furthermore, the battery life, while decent at 6 to 8 hours, falls short of what heavy users might need for marathon viewing sessions without a recharge break. This headphone is best suited for the mobile user, the frequent flyer, or the student who needs a lightweight, high-quality stereo experience for music and movies on the go, rather than a stationary home entertainment hub.
The SIMOLIO JH-737D is a powerhouse designed explicitly for the living room environment, where reliability, range, and audio customization are paramount. Unlike generic Bluetooth headphones, these units operate on a robust 2.4GHz RF connection when paired with their included transmitter, delivering a staggering range of up to 164 feet (50 meters). This means you can walk from your bedroom to the garage, garden, or kitchen without losing a second of dialogue or missing a scene. The system is pre-paired, eliminating the frustrating manual pairing process common with other wireless setups, ensuring you can simply plug in the transmitter and start listening immediately.
One of the most compelling features for families is the innovative "bypass" functionality. This allows the headphones to work simultaneously with an existing soundbar or AV receiver. You can adjust the volume to your specific hearing needs—boosting clarity or dialing it down—while family members continue to watch the movie through the main speakers at their preferred level. Additionally, the three distinct EQ modes (Clear Dialogue, Standard, and Cinema) allow you to tailor the sound profile to the content. For seniors or those with hearing difficulties, the "Clear Voice" mode is a game-changer, enhancing speech frequencies without requiring complex equalizer adjustments.
The battery performance here is exceptional, boasting an average life of 20 hours on a single charge. The charging dock doubles as the transmitter base, so you never have to hunt for cables; you simply set the headphones back down when you are done. However, this performance comes with a trade-off in portability. At 1.7 pounds, these are substantial headphones compared to the featherweight RETRADEKING. They are not designed for carrying in a small pocket or wearing on a plane for eight hours straight due to their bulk and the presence of a large external transmitter. This product is the ultimate choice for the home enthusiast, the avid TV watcher, and anyone who values uninterrupted, long-duration listening without the anxiety of a dying battery.

I would personally buy the RETRADEKING Headphones Over Ear for my own needs because I prioritize portability and comfort above all else. As someone who travels frequently by air, the 1.7-pound weight of the SIMOLIO would be unbearable on a long-haul flight, whereas the 137g RETRADEKING feels almost nonexistent against my ears. The memory foam padding and lack of a tethered transmitter make it the superior choice for moving around freely, whether I am on a plane or just walking through a busy airport. While the SIMOLIO is undeniably powerful for the living room, the RETRADEKING offers the kind of freedom and lightweight engineering that transforms daily audio consumption into a truly pleasant experience.
Both options offer solid value, but the SIMOLIO is purpose-built for TV with a dedicated transmitter and 20-hour battery, while the RETRADEKING works well for TV via its USB adapter but excels more as a multi-device Bluetooth headset.
