If you want a tiny, featherweight way to add LDAC wireless audio to wired headphones you already love, choose FiiO BTR11; if you need a full over-ear noise-cancelling headphone for commuting, flights and long listening sessions, choose Amazon Renewed Edifier W820NB.
• FiiO BTR11 — biggest strength: It turns almost any wired headphone or speaker into a wireless LDAC setup, and it weighs only 12.5g.
• FiiO BTR11 — biggest trade-off: It gives you no speakers and no active noise cancellation. It is a receiver and amplifier, not a headphone.
• Amazon Renewed Edifier W820NB — biggest strength: A complete over-ear package with hybrid ANC rated at -43dB, 49 hours of playback and a 40mm driver.
• Amazon Renewed Edifier W820NB — biggest trade-off: It is a renewed unit, so it is a used-and-refurbished product rather than a brand-new one, and it is far bulkier than a clip-on receiver.
• Who the FiiO BTR11 is for: Listeners who already own good wired headphones and want to cut the cord without replacing them.
• Who the Amazon Renewed Edifier W820NB is for: Buyers who want one self-contained headphone with noise cancelling, long battery life and no extra gear to manage.
The FiiO BTR11 is best understood as a bridge. It takes Bluetooth 5.3 audio and pushes it out through a 3.5mm output to whatever wired headphones or speakers you already own. Because it supports LDAC, it can carry a far higher-quality wireless stream than the basic SBC codec most people default to, which matters if you listen on a phone or tablet that also supports LDAC. If you have a decent pair of wired headphones sitting in a drawer because your new phone has no headphone jack, this little device is the fix.
Physically, it is about as unobtrusive as audio gear gets. It weighs 12.5g and measures roughly 5.5cm, and it ships with two carrying options: an elastic back clip and a lanyard. In practice that means you can clip it to a shirt, a bag strap or a belt and forget it is there — a genuinely different experience from carrying a full headphone case. Battery life is quoted at 15 hours of continuous music playback, and when it runs low, an hour on the charger gets it back to about 90%. That is a sensible ratio for a device this small.
Amazon Renewed Edifier W820NB: Who It's For
The Amazon Renewed Edifier W820NB is the opposite approach: everything is built in. It is an over-ear headphone with a 40mm mantle-plated composite diaphragm driver, and like the FiiO it supports LDAC for high-resolution wireless listening. The listing spells out the transfer-speed gap clearly — LDAC at 990Kbps versus Qualcomm aptX HD at 576Kbps, AAC at 512Kbps and SBC at 328Kbps — which is a useful way of saying LDAC carries noticeably more data than the codecs most Bluetooth headphones fall back on. It also works wired over a 3.5mm jack, so you are not stranded when the battery runs out.
The headline feature is hybrid active noise cancellation rated at -43dB. In real terms, that is aimed at the drone of a bus or train, the hum of an office, and the steady roar of a plane cabin. It also offers seven levels of ambient sound, so you can let outside noise back in when you need to hear announcements, traffic reminders or someone talking to you. For calls, the built-in mics use DNN noise cancellation to keep your voice clear on the other end.
Comfort and stamina are the other two pillars. It weighs 7.9 oz (220g) and uses memory foam cushions with what Edifier calls zero-pressure patented earcup technology — specifically noted as comfortable even for glasses wearers, which is a detail over-ear buyers learn to care about after an hour or two. Playback is quoted at 49 hours per charge, and a 10-minute fast charge reportedly gives 7 hours of use. The renewed angle is worth naming plainly: this is a refurbished unit sold under the Amazon Renewed label, with a one-year warranty stated on the listing and a 90-day limited warranty noted elsewhere in the product details. The color here is green, the enclosure is faux leather, and the box includes the headset, a manual and a Type-C charging cable.
Side-by-Side: Which Should You Choose?
• Best for upgrading headphones you already own → FiiO BTR11. It adds Bluetooth 5.3 and LDAC to any wired pair through a 3.5mm output.
• Best for battery life → Amazon Renewed Edifier W820NB. 49 hours versus 15 hours, though the BTR11's one-hour charge to 90% is faster in percentage terms.
• Best for portability → FiiO BTR11. 12.5g and about 5.5cm with a clip and lanyard beats a 220g over-ear headphone you have to store.
• Best for glasses wearers and long sessions → Amazon Renewed Edifier W820NB. The memory foam zero-pressure earcups are designed for exactly that.
• Best for wired fallback → Amazon Renewed Edifier W820NB. It has a 3.5mm jack built in, so it keeps working without power.
• Best for calls on the move → Either, with a caveat. The BTR11 has an omnidirectional mic with call noise reduction; the W820NB uses DNN mic noise cancellation. Both are designed for voice, but only the Edifier isolates you from the room around you.
• Best if you dislike buying refurbished → FiiO BTR11. It is a new unit, while the Edifier is a renewed product with the warranty terms noted above.
In my opinion, the right pick comes down to one question: do you already own headphones you like? If you do, I would buy the FiiO BTR11. It is cheap insurance against a phone with no headphone jack, it weighs almost nothing, and LDAC over Bluetooth 5.3 is a real upgrade over standard codecs. If you do not own a good pair — or you want noise cancelling for a commute — I would buy the Amazon Renewed Edifier W820NB instead. It is the more complete product: 49 hours, -43dB ANC, 40mm drivers, wired backup and a one-year warranty. Just go in knowing it is a renewed unit, not new.
They are not really competitors. The BTR11 is a Bluetooth receiver that adds wireless LDAC audio to wired headphones. The W820NB is a complete noise-cancelling headphone. "Better" only makes sense once you decide whether you need a device or an upgrade.
The W820NB has its own 40mm drivers and supports LDAC, so it delivers sound on its own. The BTR11's sound quality depends entirely on the headphones you plug into it. Feed the BTR11 a good wired pair and it can sound excellent; feed it weak earbuds and it will not rescue them.
I do not quote prices here, because they change. Use the "Check latest price on Amazon" button on this page to see the current figures for both, then compare them against the specs above.
That depends on how you feel about refurbished gear. The listing states a one-year warranty, and the bundle includes the headset, manual and Type-C cable. If the warranty comfort matters more to you than the renewed status, the FiiO BTR11 is a new unit and avoids the question entirely.
