How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a drop-in Bluetooth module that brings LDAC high-resolution audio to a headband you already own, choose MUSICOZY 5.4; if you need a complete pair of over-ear headphones with serious battery life and multipoint, choose Belkin SoundForm Surround.
• MUSICOZY 5.4 — biggest strength: Bluetooth 5.4 with LDAC and LHDC codec support, up to 24-bit/96kHz high-resolution audio, and roughly three times the data rate of standard SBC — inside a cheap-to-replace module.
• MUSICOZY 5.4 — biggest trade-off: It is a replacement part, not headphones. It only works with MUSICOZY sleep headphones, and you supply the headband.
• Belkin SoundForm Surround — biggest strength: 60 hours of playback per charge, Bluetooth multipoint across two devices, and a foldable over-ear design with a 3.5mm wired fallback.
• Belkin SoundForm Surround — biggest trade-off: No LDAC or any high-resolution codec is listed. It is a comfortable everyday Bluetooth headphone, not a hi-res one.
• Pick MUSICOZY 5.4 if you already own MUSICOZY sleep headphones and want a fresh module with better codec support.
• Pick Belkin SoundForm Surround if you want one finished pair of headphones for commutes, calls and long listening sessions.
The MUSICOZY 5.4 is a Bluetooth module, and that single fact shapes everything. It is built to slot into MUSICOZY Bluetooth sleep headphones when the original module wears out or you want to upgrade the wireless side. It is not a standalone product, and it will not work with any other brand's headband. If you are shopping for headphones from scratch, this is not that.
Where it earns its keep is the spec sheet. Bluetooth 5.4, plus LDAC and LHDC codec support, means this module can carry up to 24-bit/96kHz high-resolution audio — roughly triple the data rate of plain SBC. That matters if you stream from a service that offers hi-res tiers and you want the headband to actually take advantage of it. Around the audio side you also get composite drivers, a 40mm dynamic driver, 32-ohm impedance and a 20Hz–20kHz frequency range, which is the standard full-range window. Dual-microphone ENC handles calls and cuts background noise, and there is a proper safety package: NPC high-temperature protection, over-voltage protection and battery protection circuitry, backed by a pure cobalt cell rated at about 14 hours of average battery life.
Charging is over Type-C, and the cord is described as flexible and durable so it survives being folded into a headband night after night. Controls are push-button volume. One thing to be clear about: noise control is listed as "None" — the ENC is for your voice on calls, not for cancelling sound around you. In my opinion, this is the right buy for someone who already loves their MUSICOZY sleep headphones and wants the best wireless version of them. Skip it if you need over-ear headphones, multipoint, or anything you can wear without a headband.
The SoundForm Surround is the opposite kind of product: a finished pair of over-ear headphones you unbox and wear. The headline number is 60 hours of battery life on a single charge, with a 10-minute charge time listed for quick top-ups — the kind of figure that means you can take a trip and not think about the charger. Bluetooth 5.4 gives you a stable connection within a 33-foot (10m) range, and multipoint lets you stay paired to two devices at once, so you can jump between a laptop call and music on your phone without re-pairing.
Comfort is the other pillar. The ear cups are pillowy soft, the headband adjusts to fit different head sizes, and the whole thing folds down for travel. Materials lean practical — plastic, fabric and foam in black — and the packaging includes a 3.5mm AUX audio cable and a USB-C charging and audio cable, so you have a wired option when you want one. Sound comes from 40mm dynamic drivers across a 20Hz–20kHz range, and a built-in microphone with environmental noise cancellation keeps calls clear.
What you do not get is high-resolution codec support. There is no LDAC or LHDC anywhere in the spec sheet. That is the honest trade-off: this is a comfort-and-battery headphone, not a hi-res one. I would point most commuters, students and remote workers here. I would point an audio purist chasing 24-bit/96kHz elsewhere.
• Best for high-resolution audio → MUSICOZY 5.4. LDAC and LHDC support with up to 24-bit/96kHz is the differentiator here, and the Belkin does not list it.
• Best for battery life → Belkin SoundForm Surround. 60 hours versus roughly 14 hours is not close.
• Best for calls on the move → Belkin SoundForm Surround. Multipoint across two devices plus ENC mic, in a headphone you can wear anywhere.
• Best for sleep and relaxation → MUSICOZY 5.4. It is designed for MUSICOZY sleep headbands, which is a very different use case from over-ear listening.
• Best for travel → Belkin SoundForm Surround. Foldable design, adjustable headband and a 3.5mm cable for planes and wired sources.
• Best for replacing a worn-out module → MUSICOZY 5.4. Straight swap, Type-C charging, one-year warranty.
• Best for wired flexibility → Belkin SoundForm Surround. The 3.5mm jack gives you a fallback the module simply does not have.
• Best if you own nothing yet → Belkin SoundForm Surround. It is the complete product; the MUSICOZY module needs a headband to do anything.
I would buy the Belkin SoundForm Surround for most people, because it is a complete, comfortable over-ear headphone with 60 hours of battery, multipoint and a wired option — the things that matter day to day. I would buy the MUSICOZY 5.4 only if I already owned MUSICOZY sleep headphones and wanted LDAC-grade wireless audio on them. If you are torn purely on codec quality, the MUSICOZY module wins on paper; if you are torn on everything else, the Belkin wins. Check the current price on Amazon for both before deciding, since value depends on what you are replacing.
what is ldac headphones
LDAC is a Bluetooth audio codec that carries far more data than standard SBC — in the MUSICOZY 5.4's case, up to 24-bit/96kHz, roughly three times the SBC data rate. "LDAC headphones" simply means headphones whose Bluetooth chip supports that codec, so a compatible source can send higher-resolution audio to them.
what is ldac support in headphones
It means the headphone can decode LDAC streams, which requires both the headphones and your phone or player to support it. In this comparison, only the MUSICOZY 5.4 lists LDAC (and LHDC) support; the Belkin SoundForm Surround does not list any high-resolution codec.
what is ldac codec in headphones
It is Sony-developed Bluetooth audio coding that prioritizes bitrate over compression, which is why it is associated with hi-res listening. The practical benefit only shows up with hi-res sources and a transmitting device that also supports LDAC.
what is ldac sony headphones
The term usually refers to Sony headphones using Sony's LDAC codec. LDAC itself is not exclusive to Sony hardware — the MUSICOZY 5.4 module supports it too — but the name sticks because Sony developed and popularized it.
