• ULTECHNOVO Retractable Earbuds — biggest strength: the retractable winder. The cable rolls back into a compact white body measuring roughly 12 x 3 x 1.2 cm, so there is no loose wire knotting up in a bag.
• ULTECHNOVO Retractable Earbuds — biggest trade-off: it is a wired 3.5 mm in-ear only. No Bluetooth, and it will not work with a phone that has dropped the headphone jack.
• ESSGUO Over-Ear — biggest strength: wireless freedom plus flexibility. Bluetooth 5.0 with roughly 10 m of range, and a 3.5 mm jack as a wired fallback.
• ESSGUO Over-Ear — biggest trade-off: it is a full-size over-ear you have to carry and store, not something that disappears into a pocket.
• Who each is for: ULTECHNOVO suits the minimalist traveler with an MP3 player, CD player or older device; ESSGUO suits the traveler who wants one headphone for music, calls, gaming and desk work.
This is a deliberately simple product, and that is the point. It is a wired in-ear earphone with cushioned earplugs and a telescopic cable mechanism built into the housing. You pull the cable out to listen, and the winder takes it back in when you are done. The stated trick is to pull both sides of the retractable cord at the same time for a cleaner retraction.
The shell is ABS with PVC elements, the finish is white, and the whole thing is built around portability. It fits in a pocket, a jacket zip, or the small front pouch of a travel bag. Frequency range is listed at 20 Hz to 20,000 Hz, which is the standard full-range band for everyday listening, and the earpiece shape is rounded tips with in-ear cushions for a seated fit.
Who should skip it? If your phone has no headphone jack, or you want to move around untethered, this is the wrong tool. It is also a single-item package — one earphone — so there is no case, no adapter and no dongle in the box. And because the cable retracts mechanically, it rewards gentle handling rather than yanking.
ESSGUO Over-Ear: Who It's For
The ESSGUO Over-Ear is the opposite philosophy: one headphone that tries to cover everything. It runs Bluetooth 5.0, which the listing positions against older 4.2 for lower delay, better anti-interference and faster transmission — that low-latency angle is exactly what matters when you are watching video on a plane or gaming, where audio lag is the thing that ruins the experience.
The driver is a 40 mm dynamic coil paired with what the brand calls a precision sound chamber, and the frequency range covers 20 Hz to 20,000 Hz with 32 ohm impedance. Impedance that low means it is easy to drive from a phone or laptop without extra gear. The design is on-ear with circular earcups, a black ABS shell, and skin-friendly memory-protein earmuffs and headband padding — the part that actually decides whether you can wear these through a long-haul flight.
Two features stand out for travel specifically. First, the foldable build: it collapses for packing, which is the difference between a headphone that goes in your carry-on and one that stays home. Second, the connectivity options. Bluetooth for wireless, a 3.5 mm AUX cable for when the battery is not an option or when you are plugging into an in-flight system, and TF card playback support as a third path (the card itself is not included). The listing also mentions LED lighting on both earcups that reacts to the music — a style choice that will delight some buyers and feel like overkill to others.
The built-in mic and voice control method make it a workable headset for calls and meetings, not just music. Sound isolation, rather than active cancellation, is the listed noise control, so it reduces rather than erases cabin noise.
Who should buy it? Travelers who want one headphone for the plane, the hotel, the desk and the game. Anyone who wants wireless for most of the day but keeps a cable as a safety net. And anyone who prefers an over-ear fit over something pushed into the ear canal.
Side-by-Side: Which Should You Choose?
• Best for wireless travel → ESSGUO Over-Ear. Bluetooth 5.0 with roughly 10 m of range, no cable required.
• Best for tangle-free packing → ULTECHNOVO Retractable Earbuds. The retractable winder is the entire design premise.
• Best for older or wired-only devices → ULTECHNOVO Retractable Earbuds. Any device with a 3.5 mm socket, including MP3 and CD players.
• Best for calls and meetings → ESSGUO Over-Ear. Built-in mic plus voice control; ULTECHNOVO has no listed microphone.
• Best for long listening sessions → ESSGUO Over-Ear. Memory-protein earcups and headband padding are made for extended wear.
• Best for low-latency video and gaming → ESSGUO Over-Ear. The Bluetooth 5.0 low-delay claim is aimed squarely at this.
• Best as a pocket spare → ULTECHNOVO Retractable Earbuds. Compact, lightweight, one-piece, no charging involved.
• Best for flexible sources → ESSGUO Over-Ear. Bluetooth, 3.5 mm AUX and TF card playback in one headphone.
If I were packing for a trip and could only take one, I would take the ESSGUO Over-Ear. In my opinion the combination of Bluetooth 5.0, a 40 mm driver, the foldable frame, the memory-protein padding and the wired AUX fallback covers far more real travel situations — the plane, the hotel room, the airport desk, the game. The ULTECHNOVO Retractable Earbuds are genuinely clever at one narrow job: keeping a wired connection tidy for devices that still have a 3.5 mm socket, and they are the pick if that is your world. But as a single do-everything travel headphone, the ESSGUO does more. Check the current price on Amazon before you commit, since both sit in very different budget brackets.
FAQ
No. It is a wired in-ear earphone with a 3.5 mm jack. It connects directly to MP3 players, CD players, personal stereos and any device with a 3.5 mm sound socket.
The ESSGUO Over-Ear, in my opinion. Over-ear memory-protein cushions, a foldable frame, low-latency Bluetooth 5.0 and an AUX cable for in-flight systems make it the more versatile travel companion. The ULTECHNOVO is the lighter, more packable option if you only need wired listening.
That is what it is built for. The low-latency Bluetooth 5.0 connection targets sync-sensitive use like gaming and video, and the built-in mic with voice control handles calls and meetings.
