If you want one pair of earbuds that translates live conversations, cancels noise and runs for days, choose Relxhome NE20; if you need a simple wired retro-looking headphone that just plugs in and plays, choose ULTECHNOVO Retro Over Ear.

Relxhome NE20 vs ULTECHNOVO Retro Over Ear at a Glance

• Relxhome NE20 – biggest strength: it is a genuine multi-tool. AI translation across roughly 140 languages, 48dB active noise cancellation, an LCD touchscreen and up to 60 hours of total playtime in one small white in-ear package.

• Relxhome NE20 – biggest trade-off: it is app-dependent for translation, needs a stable Bluetooth and network connection, and it is very much a tech gadget rather than a classic headphone.

• ULTECHNOVO Retro Over Ear – biggest strength: zero friction. A wired plug-and-play headphone in a vintage black look that never needs charging.

• ULTECHNOVO Retro Over Ear – biggest trade-off: no Bluetooth, no noise cancelling, no microphone features spelled out in the spec sheet, and no warranty listed.

• Pick the Relxhome NE20 if you travel, take calls, work in noisy spaces or deal with people who speak other languages.

• Pick the ULTECHNOVO Retro Over Ear if you want cheap-looking-good simplicity, a costume or photo prop, or a desk headphone that just works when you plug it in.

Relxhome NE20: Who It's For

The NE20 is best understood as a travel and work companion rather than a plain music earbud. Its headline feature is real-time AI translation across roughly 140 languages, which the sheet describes as working for face-to-face conversation, business meetings and multilingual families. That is a genuinely unusual capability for an in-ear product, and it is the reason most people would even consider this model.

Around that core, the specs stack up well. Active noise cancellation rated at 48dB is listed as blocking about 97.69% of background distraction, which points at commutes, open offices and study sessions. Battery life is quoted as up to 60 hours total with roughly 6–8 hours per charge, so a long-haul flight or a week of short commutes is not a problem. Latency is listed at 45ms, which matters for gaming and video, and a six-microphone array is there to keep calls clear in windy outdoor conditions. The LCD touchscreen handles music, calls, alarms, noise modes and even small stress-relief games.

Who should buy it: frequent travellers, remote workers on constant calls, students in noisy dorms or libraries, gamers who want low-latency wireless, and anyone who regularly talks with people across a language barrier. Who should skip it: people who want a no-fuss analog headphone, anyone unwilling to install and use a companion app, and buyers who dislike touch controls. Translation only works through the app, and it needs a stable network plus Bluetooth, so it is not a magic offline box. If the connection is poor, expect delays. Also worth knowing: the earbuds can run independently, and there is a 10-second power-button reboot trick if pairing or charging misbehaves. Check the current price on Amazon before deciding, since value here depends heavily on what you pay for that feature set.

ULTECHNOVO Retro Over Ear: Who It's For

This is a different animal entirely, and it makes no apology for it. The ULTECHNOVO Retro Over Ear is a wired headphone with a standard jack plug, a vintage black look and a PVC sponge build. You plug it into a computer, phone or audio player and it plays. No charging, no pairing, no app, no firmware.

The pitch is aesthetic and practical at once. The sheet frames it as suitable for studio and travel use, photography, costumes and personal music listening, and describes the sound as detailed stereo reproduction with clear vocals and instruments. The ergonomic design is claimed to reduce ear pressure for longer sessions, and the fit is described as snug and adjustable so it stays put while you move. Weight is listed at just 27.22g and the size is roughly 15 x 11 x 4cm, so this is a light, compact headphone rather than a bulky studio can.

Who should buy it: someone who wants a retro-looking headphone for photos, cosplay, a themed desk setup, or a simple wired backup for a laptop. Also anyone who finds charging and Bluetooth pairing annoying. Who should skip it: commuters who need noise cancelling, frequent flyers, gamers chasing low latency, and anyone who relies on wireless freedom or a warranty. There is no warranty listed, the connectivity is described as hybrid, and the ear placement field says in-ear even though the product name says over-ear, which is worth being aware of before you buy. In my opinion, treat this as a style-first, convenience-first headphone and judge it on that basis.

Side-by-Side: Which Should You Choose?

• Best for translation and multilingual use → Relxhome NE20. Around 140 languages, real-time, face-to-face.

• Best for noise cancelling → Relxhome NE20. 48dB ANC is a real feature here; the ULTECHNOVO lists none.

• Best for battery life → Relxhome NE20. Up to 60 hours total, 6–8 hours per charge.

• Best for calls and meetings → Relxhome NE20. Six microphones and 45ms low latency.

• Best for zero setup and no charging → ULTECHNOVO Retro Over Ear. Wired, plug and play.

• Best for retro style, photos and costumes → ULTECHNOVO Retro Over Ear. That is clearly its lane.

• Best for light weight → ULTECHNOVO Retro Over Ear. 27.22g versus a 0.12kg earbud set with case.

• Best all-rounder for a tech-forward buyer → Relxhome NE20, provided you are comfortable with an app-driven product.

My Verdict

I would buy the Relxhome NE20. In my opinion, the translation modes, 48dB noise cancelling, 60-hour battery and 45ms latency make it the far more capable product for real daily life — travel, work, study and gaming all in one. The ULTECHNOVO Retro Over Ear is a charming, simple wired headphone, and I would recommend it specifically for style, props or a no-charge desk setup. But if you only buy one, the NE20 does more, and it does it wirelessly.

FAQ

Is the Relxhome NE20 better than the ULTECHNOVO Retro Over Ear?

For features, yes. In my opinion the NE20 wins on translation, noise cancelling, battery and call quality. The ULTECHNOVO wins only on simplicity and retro looks.

Do I need an app to use the Relxhome NE20 translation feature?

Yes. Translation works only through the companion app, and it needs a stable network and Bluetooth connection. Weak connectivity can cause delays or failed translations.

Does the ULTECHNOVO Retro Over Ear need charging?

No. It is wired and needs no charging, which is its main practical advantage. It also has no listed noise cancelling and no listed warranty.

Which one is the better value?

That depends on what you need. If you want translation and ANC, the NE20 justifies itself. If you just want a wired retro headphone, the ULTECHNOVO is the simpler spend. Check the current price on Amazon for both before you commit.
