Bluetooth: This portable headphone amp connects between your phone/MP3 player and your car's AUX input. It boosts the signal so you get louder volume, fuller bass, and cleaner treble than plugging your phone directly into the car. The 16-300 impedance range means it can drive even high-impedance headphones if you want to use them in the car. Compact and rechargeable (8+ hours), toss it in your glove box.
For audiophiles and music lovers: Many laptops and phones struggle to drive high-impedance headphones (300 like Sennheiser HD600, DT880). This pocket-sized amp delivers 30mW into 16, 15mW into 300 enough to unleash the full potential of demanding headphones. The 2-stage gain switch lets you match low (16-80) or high (80-300) impedance headphones for optimal volume and dynamics. Enjoy your music with SNR >100dB and THD+N as low as 0.0003 % ultra-clean, no hiss or distortion. Studio-grade specs in a palm-sized device: Signal-to-Noise Ratio >100dB black background, no audible hiss even at max volume (silent track). THD+N 0.0003 % virtually no harmonic distortion, sound remains pure. 2-stage gain low for sensitive IEMs/efficient headphones, high for power-hungry 300 cans. 3.5 mm input and output universal compatibility with phones, laptops, MP3 players, CD players, even gaming consoles. Aluminum housing shields against electromagnetic interference, dissipates heat, and feels premium in hand.
12 hours of playtime: No more buying AAA batteries. Charge via USB (cable included) in about 2-3 hours. Enjoy 12+ hours of continuous high-quality playback enough for a cross-country flight or a full day of listening. The slim profile (95x52x13mm) slips into any pocket, backpack, or car door pocket.
