Fosi Audio DS2 USB C to AUX Headphone Amp DAC Dongle 3.5mm Jack Audio Portable Amplifier Dual Output DSD256 4.4mm Balanced High Resolution CS43131 for iPhone 15 Pro Max Plus iPad Android Phone

i already own DS1 and i was using it for my laptop with amplifier in the day time and pull it and use with mu phone and iems at night, i had to remove DS1 daily to use it on my laptop and amplifier, so to avoid any physical damage to my DS1 i ordered DS2 in republic day sale and now i am using it with my phone and i am so happy with this purchase as i was already impressed with the audio quality of fosi audio DACs. Highly recommended for audiophiles qho love to listen to pure and lossless music.

I have been using this since six months & really enjoying it. Mostly I use this to listen Apple music as it has hi res audio support with lossless audio content. With fossi ds2 dac the experience is next level

in my oneplus 13 it product 0 hiss sound and give hires audio with pair of seneheiser ie300. so from my side this is recommended. and my audio setup is oneplus 13 + fosi ds3 + seneheiser ie300

This one little chunk is big on power. Highly recommended, I got this for under 6k. There is nothing in the market even close in this bracket. Bass heads: you will love this one.. if your headphones can handle this. Audiophiles on a budget: A good amp/dac combo on the go, nothing outstanding apart from the pure power and clarity. Remember, this is technical clarity, not the kind of warm or cool or custom soundstage you can choose, that said if you have a Software DSP stack that would do it, can't think you will regret at all. Pros: - If you have a open back or closed back full sized headphones, this is a good investment - iem users would find better options but above the price bracket - Good overall soundstage, nothing amazing but power is ample on tap EQ it up and this thing will pick up - Robust build, use custom cables the stock cable is not bad but not great.. - Technically robust but the power budget here is clearly a limitation which is a problem with smartphone powered amps - All said, given the size, power consumption & audio quality with this power; it's difficult to go wrong. Cons: - At this price.. none - Very high dependance on the stock CS43131 chip - Fosi skipped on op amp tuning likely power budget issues

If the headphone drivers are 30mm and larger this product is most required. Makes a huge difference when using large headphone drivers which cannot be driven by a mobile phone. Mobile phone amplifiers are weak and hence it is necessary to use this product.

Waste purchasing this no return after receiving order no exchange also audio quality was very bad it is very waste of money

This thing sounds awesome. I have used many dongles till now even more expensive ones than Fosi DS2 but I liked the sound of DS2 more than any of them. It is musical sounding with good technicalities too

While hearing music, if you dont know the difference between mono and stereo, dont bother. If you know the quality difference between normal SBC codec and LDAC codec, then you will definitely appreciate the wired connection at 32bit/384 KHz, however you are stuck with Apple music and spotify, youtube music and the rest were simply yet to catch up for lossless audio. Simply if you are and Audiophile, you can go for it.
