qakthesilenceI use mines without an amp. They are a legit headphone without the need for an amp. Of course an amp would probably make them sound better especially with some decent tubes but I use mine straight from my computer and they are awesome. Great for movies and tv and podcasts and such.
qakthesilenceit depends.. example, like, my phone cant drive these headphones, and my pc can't on the front panel I/O. (for me: they will work, however the audio is quiet and distant.)
but, if you have a dedicated sound card in your pc or a motherboard that comes equipped with an internal amp. i dont see you needing to purchase an amp.
smallbitThat's crazy, my s6 wouldn't play them loudly at all, but when plugged into my amp they're perfect. Maybe the iPhone has better audio components? (As much as that pains me to say)
smallbitMy sam 7 has a pretty good dac and pushes lower ohms just fine. I always use an amp on anything over 32. These are 55 ohms, so use an amp. On computer, the back ports are better for several reasons. Check out the new 2017 audiphile phones. The specs for audio keep getting better on smartphones. I think its called the Htc u11 with squeeze technology. Looks interesting. Cheers!
SirnewbingtonThe iPhone 4 probably had the all-time strongest amp of any iPhone (and a Wolfson DAC chip). I've heard rumors of an android phone by LG that has a pretty respectable built-in amp.
The key takeaway is that not all headphone jacks are equal, and EVERY audio chain/system will have a DAC and an amp in it somewhere, of different quality and power. Laptop headphone jacks are usually the worst, followed by PC front panel jacks (yes, even "HD Audio" front headphone jacks), built-in motherboard audio is a little stronger/cleaner, smartphones are usually about equal to that or better, dedicated portable music players (iPod Classic, FiiO, Walkman, etc) are usually better, and then separate external amps will (should) at least match smartphone amps OR sky's the limit better. Better amping isnt (usually) about better volume, it's about supporting all the frequency ranges equally, and having lower distortion from the original recording.
EvshrugI will probably keep my iphone 4 now instead of just throwing it out, I had no idea! Will be a good portable spotify machine I guess. Thanks for the info!
smallbitYeah! The 4 was pretty boss :)
Don't get me wrong, I have several external amps that make things better (dynamic and lively, better instrument separation and clarity), but purely for volume the only headphone so far that the iPhone couldn't produce "enough" volume for was headphones based on the Fostex T50RP.
