Seulliya Lightning to 3.5mm Adapter 2-in-1 Charging DAC

Seulliya's 2-in-1 Lightning to 3.5mm adapter is an Apple MFi-certified dongle that lets you charge an iPhone while using wired headphones and delivers up to 24-bit/48kHz lossless audio.

Designed for modern iPhones without a headphone jack, this compact adapter combines a Lightning pass-through charging port with a 3.5mm audio port and an integrated high-fidelity DAC. It’s plug-and-play—no app or setup required—and ships in a 10-pack so you can keep spares in a bag, at your desk, and in the car. Built connectors and flexible strain relief are tested for long-term reliability to handle daily use.

How does this adapter let me charge and listen at the same time?

The adapter splits the single Lightning port into two functional outputs: one Lightning port for power delivery and one standard 3.5mm jack for analog headphones or aux cables. When connected to a compatible PD charger, the Lightning passthrough supports fast charging while audio plays through your wired headset.

• Simultaneous charging and audio playback without switching cables
• Works with 20W+ PD chargers for faster charging speeds
• Maintains playback controls like play/pause and volume on supported headsets

Will my iPhone recognize the adapter and my headphones?

Yes — Seulliya’s adapter is Apple MFi certified, meaning it meets Apple’s compatibility standards and avoids pop-up warnings on compatible iPhones and iPads. The unit supports standard wired headsets and line-level aux inputs for speakers or car audio.

• MFi certification for seamless device recognition and no compatibility prompts
• Supports iPhone 14/13/12/11/XS/XR/X/8/7, SE, iPad, and iPod models with Lightning
• Retains inline controls where headset hardware supports them

What audio quality can I expect from the built-in DAC?

The adapter includes a dedicated digital-to-analog converter engineered to deliver high-resolution sound up to 24-bit/48kHz. That means clearer mids and highs, improved detail retrieval, and stable digital-to-analog conversion for music, movies, and games compared with basic passive adapters.

• High-fidelity DAC supports up to 24-bit/48kHz lossless audio output
• Reduced noise and stable transmission for consistent listening
• Suitable for casual listening and clearer playback on higher-quality headphones

How durable is the cable and connector design?

Seulliya built this splitter with reinforced connectors and flexible TPE strain relief that has been tested for extensive insertion cycles and frequent bending. The construction aims to resist wear from daily pocketing, plugging, and unplugging so the adapter remains reliable over time.

• Reinforced Lightning connector and sturdy housing for everyday use
• Strain relief tested for over 20,000 insertion/removal cycles and repeated bends
• Compact, lightweight body for convenient portability and storage

Who is this for? If you own a modern iPhone or Lightning iPad and rely on wired headphones, car aux inputs, or want spare adapters for travel, the Seulliya 2-in-1 Lightning to 3.5mm adapter in this 10-pack is a practical choice. It’s ideal for commuters, families, workplaces, and anyone who needs reliable simultaneous charging and wired audio without sacrificing sound clarity. Buyers seeking a plug-and-play solution with verified Apple compatibility and improved audio performance will find this accessory useful for everyday listening and on-the-go charging.
