Single-chip and dual-DAC dongles that convert a phone's USB-C or Lightning port into a 3.5mm headphone output with dedicated audio processing. This range covers the JM6 Pro, JM6 Pro II, JM20, JM20 Max, JM30 PRO, JM98MAX, JM7 MAX, JM7, JM7L, AP7, SP7, JM04PRO, and JM12, spanning chips including the CX31993, CS43131, KT02H20, and Realtek ALC5686.
Upgrade cables with a DAC chip built into the connector, so the cable itself handles the digital-to-analog conversion. This includes the TC08 Pro, PJ3, and PJ5, which combine 5N OFC or silver-plated wiring with an onboard chip such as the C100.
OFC and silver-plated earphone cables without a built-in DAC, sold as replacement or upgrade cables for existing IEMs. This includes the JC16S (16-core), JC08S (8-core), and PJ2+/PJ2 (0.78mm pin, 5N OFC), aimed at users replacing a stock cable on earphones that already terminate to a standard audio source.
Earphone carrying cases (JCBG2, JCBG4) and silicone ear tip sets (EM04, L/M/S sizing) for fit and storage rather than audio processing.
GearyBD stocks JCALLY DAC dongles, amplifiers, and cables with nationwide delivery across Bangladesh, along with standard warranty support on eligible models. Pricing varies by model — from entry-level single-chip dongles to the higher-end JM98MAX and JM6 Pro II — so check each product page for the current price and warranty period before ordering.
Match the connector to your device. USB-C dongles (JM6 Pro, JM20, SP7, JM12, JM98MAX, and most of the range) work with USB-C Android phones and laptops. Lightning models (JM7L, JM08L) are for iPhones and are typically MFI-certified for compatibility with Apple's Lightning protocol.
Decide between a standalone dongle and a cable-integrated DAC. A dongle like the JM6 Pro sits between the phone and any 3.5mm cable, so it works with earphones you already own. A cable-integrated DAC like the TC08 Pro or PJ3 combines the cable and DAC into one plug, which is more compact but ties the DAC to that specific cable.
Check the DAC chip if you have specific headphones. The CX31993 and KT02H20 are balanced, general-purpose chips suited to most dynamic-driver IEMs and headphones. The CS43131 (JM20, JM20 Max) targets higher dynamic range and lower noise floor, which matters more with sensitive or high-impedance IEMs. The Realtek ALC5686 (JM04PRO) is a digital audio decoding chip used for that model's adapter path.
Consider whether you need a microphone. Several cables and dongles (TC08 Pro, PJ3, PJ5, JC16S, JC08S) include an inline or built-in mic for calls; adapters without "with Mic" in the name are audio-output only.
Match ear tip size and case separately. The EM04 ear tip set and JCBG2/JCBG4 cases are sold as standalone accessories and aren't tied to a specific JCALLY dongle model — they fit most IEMs and dongles by size rather than by product line.
Does a JCALLY DAC dongle work with any earphones? Yes. Any earphone with a standard 3.5mm plug can be used with a JCALLY DAC dongle, since the dongle converts the phone's digital USB-C or Lightning output to an analog 3.5mm signal. Cable-integrated models like the TC08 Pro or PJ3 only work with earphones that accept that cable's connector (typically 0.78mm or MMCX, depending on the model).
What's the difference between the JM6 Pro and JM6 Pro II? The JM6 Pro uses a single CX31993 chip, while the JM6 Pro II uses a dual-DAC configuration, which generally improves channel separation and output power over the single-chip version.
Do I need a DAC dongle if my phone still has a headphone jack? No — a DAC dongle is for devices without a 3.5mm jack, or for users who want dedicated DAC processing instead of a phone's built-in audio chip. If your phone has a headphone jack, a dongle isn't required for basic playback.
Are JCALLY Lightning adapters compatible with all iPhones? The MFI-certified models (JM08L, JM7L) are built to Apple's Lightning specification and are intended for iPhones with a Lightning port. Check the current iPhone lineup's port type before ordering, since recent models have moved to USB-C.
What does "32-bit/384kHz" mean on a product like the JA3T? It refers to the maximum resolution the DAC chip can process — 32-bit depth and a 384kHz sample rate. This is a ceiling for hi-res audio file playback; actual output quality also depends on the source file and the earphones used.
Can I use a JCALLY cable's DAC chip with a different set of earphones? Only if the earphone's connector matches the cable's plug type (commonly 0.78mm 2-pin). The DAC chip is fixed to that cable, so switching earphones means unplugging the cable's connector from the old earphone and into the new one, not swapping the DAC itself.
Where can I buy JCALLY products in Bangladesh? JCALLY DAC dongles, amplifiers, and cables are available through GearyBD with delivery across Bangladesh. Availability and pricing vary by model, so check the individual product page for current stock and price.
