SonicLink, AlphaTheta's low-latency wireless link, keeps the delay at around 9 ms, so beatmatching by ear still feels natural. At Soundium it sits as the lighter, more compact entry into the HDJ-F wireless family.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSonicLink wireless:\u003c\/strong\u003e About 9 ms latency and up to 15 m range for real-time cueing in the booth.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTouch pairing:\u003c\/strong\u003e Touch the headphones to a DJM-V5 or the HP-TX01 transmitter to connect instantly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNew 40 mm driver:\u003c\/strong\u003e PEEK-PU-PEEK composite diaphragm with a bass-reflex chamber for punchy, defined kicks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrong isolation:\u003c\/strong\u003e Closed on-ear design that blocks booth noise, so you can monitor at lower volume.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt for one-ear cueing:\u003c\/strong\u003e Swivel hangers, a flexible silicone headband and a die-cast aluminium slider.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBluetooth 5.3 multipoint:\u003c\/strong\u003e Connects to two devices with Google Fast Pair and Windows Swift Pair for everyday listening.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCustomer Benefits\u003c\/h4\u003e\n\u003cp\u003eWireless DJ headphones are only useful if the timing holds up, and SonicLink is built for exactly that. You can step away from the decks, hand over between sets or move around a crowded booth while the cue signal stays tight. When the gig ends, switch to Bluetooth for up to 25 hours of listening, and if the battery runs out, plug in the included coiled cable and keep going. The bayonet locking connector stops the cable from pulling loose mid-set, and the HEADPHONES CONNECT app lets you adjust the status LED and find misplaced headphones.\u003c\/p\u003e\n\u003ch4\u003eQuick Specs\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Closed, dynamic, on-ear\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDriver:\u003c\/strong\u003e 40 mm PEEK-PU-PEEK composite\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency response:\u003c\/strong\u003e 5 – 30,000 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImpedance:\u003c\/strong\u003e 32 Ω\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensitivity:\u003c\/strong\u003e 106 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery life:\u003c\/strong\u003e up to 9 h (SonicLink) \/ up to 25 h (Bluetooth), status LED off\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCharging:\u003c\/strong\u003e about 2.5 h via USB-C; a 30-minute charge gives about 2.5 h of SonicLink use\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWireless:\u003c\/strong\u003e SonicLink (2.4 GHz, about 15 m); Bluetooth 5.3 (SBC, AAC, about 10 m)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 285 g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eIn the Box\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eAlphaTheta HDJ-F9 headphones\u003c\/li\u003e\n\u003cli\u003e1.2 m coiled cable with L-shaped plug (about 3.0 m extended)\u003c\/li\u003e\n\u003cli\u003e6.3 mm screw-on stereo adapter\u003c\/li\u003e\n\u003cli\u003eUSB Type-C to Type-C charging cable (0.5 m)\u003c\/li\u003e\n\u003cli\u003eCarrying pouch\u003c\/li\u003e\n\u003cli\u003eQuick Start Guide\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eIdeal For\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eClub and mobile DJs who want cable-free cueing\u003c\/li\u003e\n\u003cli\u003eDJM-V5 owners using SonicLink touch pairing\u003c\/li\u003e\n\u003cli\u003eDJs who want one pair for the booth and for daily listening\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eSonicLink works with the DJM-V5 (latest firmware) and other supported AlphaTheta units, or with any mixer through the HP-TX01 transmitter.
