If you want one dongle that squeezes the lowest possible latency and the highest-resolution codecs out of almost any Bluetooth headphone you already own, choose Questyle QCC Dongle Pro; if you need a self-contained, plug-and-play wireless TV listening kit that a non-technical person can set up in seconds, choose 1Mii ClearLinkTV E5. They both attack audio delay, but from completely opposite directions — one is a codec-and-transmitter play for tech-comfortable users, the other is an appliance for the living room.
• Questyle QCC Dongle Pro — biggest strength: Bluetooth 5.4 with Snapdragon Sound, aptX Adaptive, aptX Lossless and LDAC up to 990 kbps, plus MFi certification for iPhone/iPad/Mac and a companion app for codec control.
• Questyle QCC Dongle Pro — biggest trade-off: It is a transmitter only, it will not work with two pairs of headphones at once, your headphones must support the same codec, and setup requires pairing through the Questyle App before you plug it in.
• 1Mii ClearLinkTV E5 — biggest strength: True plug-and-play 2.4G private TV listening with the earbuds and transmitter pre-paired, open-ear comfort, 18 hours of playtime, and no Bluetooth pairing at all.
• 1Mii ClearLinkTV E5 — biggest trade-off: It is a closed system for TVs (Optical, RCA or 3.5mm AUX), it does not support Bluetooth, only one audio connection at a time, and the transmitter base has no battery so it must stay plugged in.
• Who each is for: Questyle for gamers, iPhone/PC/PS5/Switch users and anyone chasing low-latency hi-res audio with their own headphones; 1Mii for seniors, late-night TV watchers and households that want private, synced TV sound without a learning curve.
The QCC Dongle Pro is a USB-C Bluetooth transmitter built around Qualcomm's latest Snapdragon Sound platform. Its whole reason for existing is the combination of Bluetooth 5.4, aptX Adaptive, aptX Lossless, aptX HD, LDAC and SBC in one tiny 2.2-gram stick measuring roughly an inch long. For the "bluetooth headphones low latency" problem, aptX Adaptive is the headline: it is designed to keep audio and video tightly synced, which is exactly what you want when you are gaming on a PS5 or Switch or watching video on a laptop and the lip-sync drift becomes obvious.
The other half of the story is Apple. Questyle states this is the first lossless Bluetooth transmitter line certified under the MFi program, and it acts as an official LDAC partner streaming up to 990 kbps. Practically, that means an iPhone, iPad or Mac user who owns LDAC or aptX-capable headphones can finally get hi-res wireless audio out of a device that would otherwise hand them a much more basic codec. Windows 10 (1803 and up) and macOS need no extra drivers, and Android 5.1 and above works too — though Android requires enabling OTG first.
Buy it if you already own good Bluetooth headphones, you game or watch video on a PS5, Switch, PC, Mac or iPhone, and you are comfortable installing an app and managing a pairing. Skip it if you want something your parents can operate without instructions, or if you need two people listening at once.
1Mii ClearLinkTV E5: Who It's For
The ClearLinkTV E5 solves a different problem entirely: hearing the TV clearly, privately, without touching the TV's volume. It ships as a set — a pair of open-ear earbuds plus a 2.4GHz transmitter box that plugs into your TV over Optical, RCA or 3.5mm AUX. The earbuds and transmitter arrive pre-paired, so there is no Bluetooth menu, no scanning, no codec talk. You plug in the base, put on the earbuds, and you are listening.
Latency is handled with 2.4GHz wireless rather than Bluetooth, which is the same approach wireless gaming headsets use. 1Mii describes it as low-latency audio with perfect lip sync for movies, sports and shows. Because it is a dedicated 2.4G link, it sidesteps the codec negotiation and interference issues that make Bluetooth delay so inconsistent on TVs.
The design choices point hard at comfort and simplicity. Open-ear earpieces sit outside the ear canal, so ear pressure stays low and you keep hearing the room — the doorbell, a family member talking, your surroundings. The companion app offers Dialogue, Movie and Standard modes, and Dialogue mode is aimed squarely at people who struggle to pick out voices from background music and effects. A Bypass mode lets audio play through both the earbuds and your external speakers at once, and multiple ClearLinkTV E5 sets can share the same TV audio with independent volume per listener.
Trade-offs are real. This is not a Bluetooth product at all, so it will not pair with your phone, tablet or laptop. Only one audio connection can be used at a time. The transmitter base has no internal battery and must stay plugged into power to run and charge the earbuds. And it is a TV system — if your TV lacks Optical, RCA or AUX output, you are out of luck.
Buy it if you want private, synced TV audio with zero setup friction, especially for seniors, hard-of-hearing viewers, or late-night watching in a shared bedroom. Skip it if you want to use your own headphones or need Bluetooth flexibility across devices.
• Best for lowest-latency gaming on PS5/Switch/PC → Questyle QCC Dongle Pro, because aptX Adaptive plus Bluetooth 5.4 targets synced audio and high-resolution sound.
• Best for iPhone hi-res audio → Questyle QCC Dongle Pro, given MFi certification and LDAC streaming up to 990 kbps.
• Best for the widest codec support → Questyle QCC Dongle Pro, with aptX, aptX HD, aptX Adaptive, aptX Lossless, LDAC and SBC.
• Best for zero-setup TV listening → 1Mii ClearLinkTV E5, since the earbuds and 2.4G transmitter come pre-paired.
• Best for seniors or non-technical users → 1Mii ClearLinkTV E5, because there is no app-based pairing step to learn.
• Best for long single-charge sessions → 1Mii ClearLinkTV E5, with up to 18 hours of playtime (measured at 50% volume; louder may reduce it).
• Best for two people watching the same TV at different volumes → 1Mii ClearLinkTV E5, thanks to Bypass mode and multi-set sharing.
• Best for using your own headphones → Questyle QCC Dongle Pro, since it transmits to the Bluetooth headphones you already own.
In my opinion, the right pick comes down to what is actually causing your delay. If you have decent Bluetooth headphones and the problem is lag while gaming or watching video on a console, phone or computer, I would buy the Questyle QCC Dongle Pro — aptX Adaptive low-latency mode, LDAC at up to 990 kbps and MFi certification make it the more capable tool, even though it asks you to set things up through an app. If instead the problem is a person in your house who just wants to hear the TV clearly without disturbing anyone, I would buy the 1Mii ClearLinkTV E5. Pre-paired earbuds, 2.4G lip sync and 18 hours of playtime beat any amount of codec spec sheet for that job. Check the current price on Amazon before you commit, since both sit in different budget brackets depending on the day.
how to make bluetooth headphones low latency
Use a transmitter that supports a low-latency codec and a headphone that supports the same one. The Questyle QCC Dongle Pro does this with aptX Adaptive over Bluetooth 5.4 — but both ends must speak the same codec, so check your headphones' spec sheet first.

On Windows 10 version 1803 and above the QCC Dongle Pro needs no extra drivers, so you plug it in and it works as a USB audio device. Pair your headphones to the dongle through the Questyle App first, then plug it into the PC and select it as the output.
do bluetooth headphones have latency
Yes — delay is inherent to Bluetooth, and how bad it is depends on the codec and the device. That is exactly why aptX Adaptive and 2.4GHz systems like the 1Mii ClearLinkTV E5 exist: both are engineered to keep audio synced with the picture rather than leaving you with visible lip-sync drift.
how to get low latency on bluetooth headphones
Two routes work. A low-latency codec transmitter such as the Questyle QCC Dongle Pro is one; a dedicated 2.4GHz system such as the 1Mii ClearLinkTV E5 is the other. The 2.4G path is simpler and pre-paired but TV-only, while the Bluetooth dongle is more flexible across devices.
