Who it fits
Good fit for
You should consider these headphones if you prioritize audio fidelity and detail. The 78mm planar magnetic driver and balanced wired connection suit listeners who want clear resolution and a spacious soundstage. The open-back design works well in quiet environments where sound leakage is not a concern. The comfortable materials, including lamb leather and velvet, make them suitable for extended listening sessions. If you value craftsmanship and precise sound layering, this model fits your setup.
Who should skip it
You should look elsewhere if you need wireless convenience. The Apollo Pro uses a 4.4mm balanced wired connection, so you must stay tethered to your source. The open-back design allows sound to escape, making it unsuitable for noisy public spaces or shared rooms. If you prefer closed-back isolation or portability without cables, this option is not for you. The specific balanced cable requirement also means you need compatible equipment to use it properly.
Verdict: The SENDYAUDIO Apollo Pro offers detailed, spacious sound for wired audiophiles who value comfort and build quality. It suits quiet, dedicated listening setups but is not ideal for mobile or noisy use.
Key specs for Apollo Pro
Driver Size: 78mm
The Apollo Pro uses a large 78mm planar magnetic driver. This size allows for a wider diaphragm surface area compared to standard dynamic drivers. You get faster transient response and clearer resolution. The larger area helps reproduce low frequencies with more authority. If you prioritize detailed soundstage and precise imaging, this size supports that goal. Compare this against smaller 40mm or 50mm drivers found in many consumer models.
Form Factor: Over-Ear, Open-Back
These headphones sit over your ears rather than on them. The open-back design means the earcups are not sealed. Sound escapes from the rear, creating a natural, spacious listening experience. This reduces internal resonance and provides a wider soundstage. You will hear more room ambience. This is ideal for quiet home listening. It is less suitable for noisy environments or shared spaces where sound leakage matters.
Connectivity: 4.4mm balanced wired
The Apollo Pro connects via a 4.4mm balanced cable. This connector carries separate signal paths for left and right channels. Balanced connections reduce crosstalk and improve channel separation. You get a cleaner signal with lower noise floor. This requires a compatible source device or adapter. It is superior to standard 3.5mm single-ended connections for detailed audio. Ensure your amplifier or DAC supports 4.4mm balanced output.
Weight: 354g
The body weighs 354 grams. This is a moderate weight for planar magnetic headphones. The build uses ultra-thin metal mesh and zebrawood earcups. This combination aims to balance durability with comfort. You can wear them for extended sessions without excessive pressure. Compare this to heavier studio monitors or lighter plastic models. The weight distribution helps keep the clamping force even across your head.
Design and Build Quality
The Apollo Pro uses a lightweight open-back structure that weighs 354 grams. This mass helps balance premium craftsmanship with comfort during long sessions. The earcups are made from compact zebrawood, which adds a natural aesthetic. You also get an ultra-thin sunburst metal mesh that covers the driver area. This layout supports natural acoustic openness.
Comfort features include a soft lamb leather headband and breathable velvet ear pads. These materials aim to reduce heat buildup and pressure. The listing notes they offer a smooth, skin-friendly feel. This design choice supports extended listening without significant fatigue. The open-back form factor means you should use them in quiet environments. Sound leakage is expected with this build.
Connectivity relies on a detachable 4.4mm balanced cable. The included triple-composite cable combines Furukawa OFC, silver-plated copper, and enameled gold-plated copper strands. This construction aims for stable signal transmission and detailed sound presentation. You must carry the cable separately if you switch devices. The wired-only nature limits mobility. You need a source with a 4.4mm output to use the balanced connection. The ZEBRANO color option defines the visual finish. There are no controls on the earcups. You adjust volume through your playback device.
Setup And Daily Use Guide
Setup begins with the detachable 4.4mm balanced cable. You connect this triple-composite cable to your audio source. The cable combines Furukawa OFC, silver-plated copper, and enameled gold-plated copper strands. This construction is designed for stable signal transmission. You will need a source that supports 4.4mm balanced output. This connectivity choice prioritizes detailed sound presentation over convenience. You cannot use these headphones wirelessly. The open-back design means you need a quiet environment. Sound will leak out, and external noise will enter. This setup suits critical listening sessions rather than commutes.
Daily use involves wearing the 354-gram over-ear headphones. The zebrawood earcups and ultra-thin sunburst metal mesh contribute to the weight. You rest the lamb leather headband on your head. The breathable velvet ear pads sit against your ears. These materials aim to reduce heat buildup and pressure. You can wear them for extended periods without significant discomfort. The planar magnetic driver requires specific amplification to perform well. You must ensure your amplifier can drive the low impedance. The EB evaporation diaphragm technology helps with vibration control. This feature supports sound layering and frequency stability during use. You get a spacious open-back listening experience. This suits HiFi music enjoyment where detail matters more than isolation. You should keep the headphones away from moisture. The wood and metal components require gentle handling. You detach the cable for storage to prevent strain on the connectors. This simple maintenance ensures long-term reliability. You enjoy the fast response and clear resolution provided by the large diaphragm. The setup is straightforward but requires the right gear.
Before You Buy Apollo Pro
These headphones are wired and open-back, so you need a compatible source. You must check for a 4.4mm balanced output. Standard 3.5mm or 6.35mm jacks will not work directly. You will likely need a dedicated digital-to-analog converter or amplifier. The open design means sound leaks out. You should use them in quiet rooms. Do not wear them on public transit. The zebrawood earcups and lamb leather pads need gentle care. Avoid direct sunlight to prevent wood damage. Wipe the metal mesh with a dry cloth. Keep the cable coiled loosely to preserve the triple-composite strands. Compared to closed models, these prioritize soundstage over isolation. They fit well if you value HiFi accuracy. They are less suitable for noisy environments. Consider your listening space carefully before purchasing.
Check before you buy
- Verify your audio source has a 4.4mm balanced output.
- Ensure you have a quiet room for open-back use.
- Check for a compatible amplifier or DAC.
- Confirm you prefer isolation over noise cancellation.
