If you want a wired, zero-latency connection for TV and PC listening that never needs charging, choose Avantree HF039; if you need a fully wireless, pocket-sized earbud set for music and calls on the go, choose Yeforu Black Long Battery.
• Avantree HF039 — biggest strength: a 16.4 ft / 5 m coiled cable with in-line volume and stereo/mono switching, so you get unlimited, lag-free listening without ever worrying about battery.
• Avantree HF039 — biggest trade-off: it's wired and has no microphone, so it can't be used for calls or moving around the room freely.
• Yeforu Black Long Battery — biggest strength: true wireless Bluetooth earbuds with a semi in-ear fit, two sound modes and a long-battery design aimed at all-day, cable-free use.
• Yeforu Black Long Battery — biggest trade-off: it's positioned by the brand itself as a budget spare set, so it prioritizes value and comfort over premium sound.
• Who each pick is for: Avantree HF039 for a fixed seat in front of a TV or desktop; Yeforu Black Long Battery for someone who wants cheap, comfortable wireless earbuds for phone and tablet use.
The HF039 is a specialist, and it knows it. This is an over-ear wired headphone built around one problem: watching TV from across the room without a cable that yanks the set off the shelf. The 16.4 ft / 5 m coiled cord is measured fully extended, and the coil gives you slack rather than the tight, snag-prone pull of a straight wire — in practice Avantree says you get well over 10 ft / 3 m of effective distance before anything tugs. The in-line volume control sits on the cable, so you adjust loudness at your fingertips instead of hunting for a remote. There's also a stereo/mono switch, which matters more than it sounds: if you only hear sound in one ear with stereo mode on, flipping to mono fixes it.
On the audio side, the 40 mm dynamic drivers, 32 ohm impedance, 20Hz–20kHz range, 101 dB sensitivity and sound-isolation design point to a big, easy-to-drive over-ear sound that a TV headphone jack can handle without extra amplification. The whole thing weighs 155 g / 5.5 oz, and the super-soft over-ear pads plus adjustable headband are clearly aimed at long evening sessions. A collar clip keeps the cable from swinging loose.
Buy it if you want a dedicated TV or PC headphone with no charging, no pairing and no latency. Skip it if you need to take calls — there's no microphone — or if you want to walk around while listening. It's also worth noting it terminates in a 3.5 mm jack, so TVs and AV receivers with RCA or 6.35 mm outputs need a separate adapter, and you'll likely need to switch your TV's audio setting to "Headset" or "External Speakers."
The Yeforu Black Long Battery is the opposite philosophy: no wires at all. These are true wireless Bluetooth earbuds with a semi in-ear design that deliberately avoids pushing into the ear canal. That's the detail I'd focus on if you've ever had earbuds ache after an hour — the ergonomic shape is built to keep your ears breathable during long listening sessions. The long-battery framing in the name tells you the priority: staying alive through a full day rather than chasing the highest possible fidelity.
Sound-wise, the Yeforu gives you two modes. Classic Mode aims for a balanced, non-boomy low end so you don't get listening fatigue, while Super Bass Mode switches on with a 1.5-second long-press on the right earbud and pushes a much deeper, resonant bottom end. If you listen to bass-heavy music, that toggle is the feature you'll actually use. The 32 ohm impedance matches the Avantree on paper, but the plastic-bodied, in-ear build keeps it light and travel-friendly rather than studio-oriented.
Side-by-Side: Which Should You Choose?
• Best for TV and desktop listening → Avantree HF039. The 16.4 ft coiled cable and over-ear pads are built for a fixed seat.
• Best for wireless freedom and travel → Yeforu Black Long Battery. No cable, no jack, no tether.
• Best for latency-sensitive audio → Avantree HF039. A wired 3.5 mm connection sidesteps Bluetooth delay entirely.
• Best for long, comfortable all-day wear → Yeforu Black Long Battery. The semi in-ear shape avoids ear-canal pressure.
• Best for bass lovers who want control → Yeforu Black Long Battery. Super Bass Mode is a one-press toggle.
• Best for shared or one-ear listening fixes → Avantree HF039. The stereo/mono switch solves one-sided audio.
• Best for calls → neither, strictly. The HF039 has no microphone, and the Yeforu is framed as a spare music-first set.
• Best for someone who hates charging → Avantree HF039. It's wired, so battery life is a non-issue.
• Best value pick for casual mobile use → Yeforu Black Long Battery. It's positioned as an affordable everyday spare.
In my opinion, these two don't really compete — they solve different problems, so buy for your main use case. If your priority is watching TV or working at a PC with zero lag and zero charging, I'd choose the Avantree HF039; the coiled 5 m cable, in-line volume and stereo/mono switch are exactly what that setup needs. If your priority is affordable, comfortable wireless listening from a phone, I'd choose the Yeforu Black Long Battery for its semi in-ear fit and dual sound modes. Only one of these fits a fixed TV seat, and that's the Avantree.
