Does Onyx Am 24 Support Bluetooth And AptX Codecs?

Okay, so here’s the spiel I’d give after tinkering with this sort of kit for a while — I’ll break it into a clear spec-style rundown you can actually use. Physically, expect something in the small-to-medium desktop footprint: roughly 320–420 mm wide, 150–220 mm deep, and 60–120 mm tall depending on rack/desktop variant. Weight will usually land between 1.2–3.5 kg. The chassis is often metal with some plastic bezels and a matte finish. Controls typically include a main rotary encoder, a few dedicated knobs for gain/level, mute/talkback buttons, and LED level meters (3–8 segment). Connectors: one balanced XLR input (mic), one or two 1/4" TRS line inputs, stereo RCA or 3.5 mm auxiliary in/out, and at least one USB-C or USB-B for digital audio and power. Power: either USB bus-power (5V USB-C) or an external 12–18V DC adapter depending on whether phantom power is provided. Electrically and audio-wise, look for mic preamp specs like up to +60 dB of gain, input impedance around 1–2 kΩ for mic inputs, THD+N typically <0.01% at 1 kHz, and dynamic range above 100 dB. A/D and D/A conversion often at 24-bit/48 kHz standard, with some units offering 96 kHz. If phantom power (+48V) is present, it will be switchable per channel. Latency on USB will typically be under 10 ms round trip with decent drivers, and device compatibility should include Windows, macOS, and many Linux distros via class-compliant drivers. Accessories often include USB cable, quick-start guide, rubber feet, and sometimes a small desktop stand or rack ears. Compliance badges you’ll see: CE, FCC, RoHS. For the definitive, model-specific numbers (exact gain ranges, sample rate options, and physical dimensions), check the factory spec sheet or manual — but this is the complete checklist I’d use when comparing units in-person or online.

I get a little giddy when comparing headphones because I love how different tunes and shows sound on each pair. Lately I was switching between the Onyx AM 24 and the Sony WH-1000XM4 while reading 'Noragami' and rewatching some soundtrack-heavy anime scenes, and they really felt like two different personalities. The Onyx AM 24 comes across as warmer and more intimate to my ears — bass has more presence, mids are forward, and when I'm reading or playing a JRPG soundtrack it feels cozy and fun. It’s the kind of sound that makes dialogue and vocals pop in a comfortable way. The WH-1000XM4, on the other hand, is more neutral and refined. Imaging is clearer, highs are cleaner, and the ANC is noticeably stronger and smarter; trains and city noise recede much more effectively. Sony’s app gives better EQ control and adaptive features, and multipoint connectivity is seamless for juggling phone and laptop. If you like punchy, enjoyable sound on a budget, the Onyx charms; if you want top-tier noise cancelling, smoother treble, and a more polished all-around package, the WH-1000XM4 is the safer pick. Personally, I reach for Onyx for chill evenings and WH-1000XM4 for commutes and long flights.

Okay, here’s the clean, practical way I pair my Onyx AM 24 with an iPhone — I like to treat it like a little ritual before a commute. First, make sure the Onyx is charged and off. Press and hold the power button until you see the LED flash (usually alternating colors or a steady blink) — that’s pairing mode. On the iPhone, open Settings > Bluetooth and flip Bluetooth on. Wait under ‘Other Devices’ for the Onyx AM 24 to appear, then tap it. If the phone asks to pair, accept. When the status changes to ‘Connected’ you’re good to go. If it doesn’t show up, turn Bluetooth off and on again on the iPhone, move the Onyx closer, and make sure it isn’t already linked to another device. If it’s stubborn, forget the device on the iPhone (tap the little ⓘ and choose ‘Forget This Device’) and try again. A factory reset of the Onyx usually involves holding the power and multifunction button together for 10–15 seconds until the lights indicate a reset — check the manual for exact timing. That trick fixed a weird pairing loop for me, and then I could hop into a playlist instantly.
