Yeah, I was going to pick up used iphone 5 for 100€, but after listening friends iphone with my Cipher I'm glad I saved the 100€.
But Cheese_sandwich here is of opposite opinion. He tested isines with LG, I assume he used most of recommended, and widely agreed upon EQ presets in order to form his opinion. Or did he just stick isines to phone's 3.5mm audio out, he wouldn't be uninformed to such degree?
We have Audezs to thank for this tho, people give isines a try with regular cable, no idea about the EQ requirements, and they won't buy isines unless they own idevice. I feel bad for these people, they are missing out on outrageous sound quality for almost no money, I see isine 10 listed at $200 everywhere, but with half decent source isine 20 are scary close to $1999 LCD-3. This is the most incredible value I've come across in 20 years of portable audio hobby, going back to original Corey Greenberg's review of Grado SR60 in Stereophile, 1993, using them with Sony Cassette Walkman WM D3, and Sony pocket Minidisc, little later pocket DAT. hat's actually 25 years lol.
Edit, Corey Greenberg's review of Grados was in 1994, a fun read even today, gives a great perspective where we've come in 24 years. The only portable sources where Sony Cassette Walkmans D6 and smaller brother D3. Pocket DATs were around, 2 models, fairly bulky. Minidisc arrived in 1991, I bought Sony MZ1 portable minidisc recorder/player at $1000 Canadian. And Philips' Digital Compact Cassette player, DCC, they made 1 portable machine, before the format folded. I remember saving money from bike messanger job in Toronto in order to buy $1400 Sony pocket DAT walkman. Grado SR60 cost $56.00 CDN at Bay & Bloor Radio.
SR60 review here, great read:
