Hey guys, I've been reading through head-fi for quite a while now and have just recently decided to create an account. I am by no means an audiophile but I do tend to become picky on the headphones I use (for the sound quality and comfort as well as and most importantly durability)
I've broken my fair share of headphones in the past, one of which was a relatively pricey (at least for me :P) Pioneer headphones. They broke quite fast as I was expecting them to last at least a year.
Recently, the Sennheiser brand had caught my attention. My friend has a Sennheiser 201s from over 2 years ago and they are still rock solid save for some wear here and there. Honestly they sound amazing for the price, well balanced and suite my tastes well.
However, the downside about the 201s was that it wasn't loud enough. Sure it was great when you're at home, relaxing in your quiet corner of the world but when you use the headphones for commuting/public purposes, they just won't do. The volume output is just too weak :| (BTW the audio source is just my phone, but other headphones do just fine??)
Before I go on, please don't flame when you see something wrong in the following paragraphs. I'm a total noob at headphone's technical stuff.
Alright, so I did a little research about why the 201s sound weak, and turns out only a handful of people has this problem? The one I tried at my local store sounded the same as my friends pair, great sound quality yet lacks in the volume department.
I've looked at the specs of different headphones and found that the 201s have 24 ohms of Impedance (what's this? :P sorry, i really have no clue) and the over-ear skullcandys have 32 - 50 ohms Impedance range, while the Senn. HD 280 have 60+ ohms.
At Sennheiser's website, the HD 280s is suppose to be compatible to almost any audio source, at least that's how I understood it, and I know for a fact that the HD 201's volume is below average.
Sooooo, my question is, does the Impedance have anything to do with the loudness of headphones? Also, which Sennheiser headphones should I get for non professional use such as commuting and personal entertainment?
Thank you in advance!
