Seeking Portable DAC Recommendations for iPhone and Laptop

Hi everyone,

I'm looking for recommendations for a portable DAC to add to my current audio setup.

Here's a summary:

Headphones:

​

• Letshuoer S12 Pro (2.5mm, 4.4mm, 3.5mm)

• HiFiMAN HE400SE (3.5mm, 6.5mm adapter and 2.5mm cable)

Current Setup:

​

• Bluetooth DAC: FiiO BTR5 (used for various purposes)

• Single DAC used with both iPhone (evenings/nights) and laptop (mornings)

Problem:

Switching the DAC between my iPhone and laptop is inconvenient.

Goal:

Purchase a second portable DAC to simplify usage.

I would primarily use the BTR5 for other situations.

Request:

I'd appreciate suggestions for portable DACs suitable for either nighttime movie watching or morning work sessions. Please consider compatibility with my headphones and specify if any additional adapters are needed.

Thanks in advance for your help!
