If you want one pair of wireless over-ear headphones for music, calls and all-day listening, choose JBL Tune 720BT; if you need a wired classroom set of 20 headphones for students, choose YFSFQS 20. These two products share almost nothing except the word "headphones" — one is a single Bluetooth listening device, the other is a bulk education pack. Here is how I'd decide between them.
• JBL Tune 720BT — biggest strength: wireless Bluetooth 5.3 freedom with up to 76 hours of playback per charge, plus app-based EQ tuning.
• JBL Tune 720BT — biggest trade-off: it's one pair of headphones with no wired jack, so it can't serve a room full of students.
• YFSFQS 20 — biggest strength: a 20-pack of wired on-ear headphones with 3.5mm jacks, built to equip a whole class at once.
• YFSFQS 20 — biggest trade-off: wired only, no Bluetooth, no app, no noise control — it's a plug-in-and-listen tool, not a personal audio upgrade.
• Choose JBL Tune 720BT if you're buying for yourself: commuting, working, calls, long listening sessions.
• Choose YFSFQS 20 if you're buying for a classroom, school, or group and need many headphones on a shared budget.
The Tune 720BT is a personal listening product. It's a wireless over-ear headphone with Bluetooth 5.3, a 40mm dynamic driver, 32 ohm impedance, 20 Hz–20 kHz frequency response and 101 dB sensitivity. In plain terms: it's designed to stream from a phone, tablet or laptop with no cable at all. There's no headphone jack here, so once you commit to this model, you're committing to wireless.
The headline feature is battery. JBL rates it at up to 76 hours of playback, with a full charge in about 2 hours over USB-C. A 5-minute top-up gives roughly 3 extra hours — the kind of detail that matters when you realize you forgot to charge before a flight or a long workday. Around 220 g, it's light enough to wear for hours, and the flat-folding design means it collapses into a backpack without much fuss.
Who should buy it: anyone who wants one comfortable wireless headphone for music, podcasts, calls and travel, and who values long battery life over everything else. Who should skip it: buyers who need a wired 3.5mm connection, who want true active noise cancellation, or who need multiple units for a group.
YFSFQS 20: Who It's For
The YFSFQS 20 is a different category entirely. It's a bulk set of 20 wired on-ear headphones in mixed colors, aimed squarely at classrooms, schools and kids' programs. Each pair uses a 3.5mm jack that plugs straight into a Chromebook, laptop, PC or computer — no pairing, no charging, no setup. You hand them out, students plug in, done.
The design is practical rather than premium: lightweight construction with padded ear cushions and an adjustable headband that JBL-style adjustability aside, is meant to fit a range of head sizes from kids to adults. The cord is 1.2 m (about 47 inches), which is short enough to avoid tangling chaos across a desk but long enough to reach a laptop sitting slightly off to the side. The 32 ohm impedance matches typical low-power devices, so a Chromebook or phone drives them without an amp.
What you don't get: Bluetooth, an app, EQ customization, voice assistants, or any noise control — the sheet lists noise control as "None." These are clear-sound, comfortable, no-frills headphones built to survive being passed around a classroom. The mixed-color 8-color assortment also makes it easy to spot which pair belongs to which student or table group. YFSFQS backs the set with a 1-year warranty and a satisfaction guarantee with a stated 12-hour response time for questions.
Who should buy it: teachers, schools, computer labs, tutoring centers and anyone outfitting a group with plug-and-play wired headphones. Who should skip it: anyone buying for personal wireless listening. Twenty wired headphones won't replace one good Bluetooth pair.
• Best for battery life → JBL Tune 720BT. Up to 76 hours per charge, with a 5-minute quick charge for about 3 more hours.
• Best for wireless freedom → JBL Tune 720BT. Bluetooth 5.3, no cable, no dongles.
• Best for app customization → JBL Tune 720BT. The JBL Headphones App adds EQ tuning and multilingual voice prompts.
• Best for calls → JBL Tune 720BT. Voice Aware and on-cup controls keep calls hands-free.
• Best for a classroom or group → YFSFQS 20. Twenty wired headphones, mixed colors, one purchase.
• Best for zero-setup compatibility → YFSFQS 20. The 3.5mm jack works with Chromebooks, laptops and PCs instantly.
• Best for kids and shared use → YFSFQS 20. Lightweight, padded, adjustable, and built to be handed out and collected.
• Best for one-person everyday listening → JBL Tune 720BT. It's simply the wrong tool for a group, and YFSFQS 20 is the wrong tool for solo wireless use.
If I were buying for myself, I'd pick the JBL Tune 720BT. Up to 76 hours of battery, Bluetooth 5.3, app EQ, Voice Aware calls and a flat-folding 220 g frame make it the more capable personal headphone by a wide margin. I'd only choose the YFSFQS 20 if my actual job were equipping a classroom — in which case 20 wired, plug-and-play pairs beat one wireless model every time. Match the product to the job, and there's no real contest: personal listening goes to JBL, group classroom use goes to YFSFQS.
how to headphones work
A headphone converts an electrical audio signal into sound using a driver — the JBL Tune 720BT uses a 40mm dynamic driver, while YFSFQS 20 uses on-ear drivers fed through a 3.5mm jack. The JBL receives that signal wirelessly over Bluetooth 5.3; the YFSFQS 20 receives it through a physical cable.
how to headphones on iphone
The JBL Tune 720BT pairs to an iPhone over Bluetooth 5.3 and can be controlled with Siri. The YFSFQS 20 is wired only, so it needs a 3.5mm jack — iPhones without that port require an adapter, which the YFSFQS 20 set does not include.
how to headphone mode off
"Headphone mode" usually refers to a device routing audio to a connected headphone. On the JBL Tune 720BT, disconnect Bluetooth or power the headphones off and the phone returns to its speaker. With the YFSFQS 20, simply unplug the 3.5mm jack.

Choose based on connection: wireless for personal listening (JBL Tune 720BT, Bluetooth 5.3, up to 76 hours) and wired for shared or classroom use (YFSFQS 20, 3.5mm jack, 20-pack). Check the current price on Amazon before deciding, since both are sold there.
