AKG K 845BT Bluetooth Wireless On-Ear Headphones, Black

I was worried after reading mixed reviews on the product, along with the only account selling this at the time having only 7 reviews I couldn't tell were legitimate or not, being a newer account. (AuctionSeller) However, I had nothing to worry about afterall!LEGITIMACY / SELLER:I paid extra for faster shipping and it did arrive quickly. The box was directly from AKG, refurbished, and packaged carefully. I could not see any fingerprints on the glossy screen, scratches or other cosmetic flaws.PRICE:$130 (which ended up being around $150 after extra fees like tax and faster shipping) is definitely a steal considering these sell for around $300 or even more.DESIGN:Like another reviewer on here, I also bought these for a Futaba Sakura cosplay (but did want good quality, daily wear headphones as well). It's very, very comfortable to wear and blocks out a decent amount of noise (but not 100%). Sometimes I forget I have them on, unlike other headphones and earbuds.All the padding is extremely soft to the touch and my ears or head don't hurt when wearing for a prolonged amount of time. When worn around the neck they're a little tight but not too choking. The glossy logo picks up fingerprints easily but can be wiped off just as easily.SOUND QUALITY:Provided cable worked without problems. I am no professional in the audio department by all means but the quality isn't bad at all. The sound is fine, too, and the volume doesn't need to be turned up a large amount to listen well. And trust me, I get it. I love loud music. But I can't imagine turning up the volume all the way and still thinking the sound was too quiet. I believe reviewers that think so received defective products.OVERALL:High quality headphones that are the exact model my favorite character wears, super comfortable, less than $200, and look amazing? These were a great deal! I'm even eyeing the white version too. Can't find complaints or flaws, except maybe it would be nice if they arrived with a carrying case of some sort, but that's it.[Will probably update later with images and a section on the Bluetooth function when I use it more!]

Quite comfortable for me, well-made and very good sound quality. Bluetooth sound quality is HIGHLY dependent upon the BT "sender" - find something that supports aptX codec. I used the Creative BT-W2 with these headphones and quality was MUCH better than stock Lenovo bluetooth. Range was also much better with the BT-W2. Paired well with my S5 phone and sound quality was excellent. I can *just* get all my ear inside the cushion which makes them much more comfortable; my ear size is pretty "normal". These are not a $300 pair of headphones as I think they originally went for, but they're decent for $180. Not studio-quality, but no BT headphones right now will be - this is a limitation of bluetooth and not necessarily the headphones. Corded quality IS better, IF you have a high-quality input, but still not a $300 pair of headphones. I also like how they fold relatively flat (like DJ headphones) for throwing in a laptop case. Contrary to other reviews, shutting them off is a matter of hitting the round button on them (controls power/pairing).One odd thing I ran into is I couldn't charge these with a li-ion battery pack... autosensing either in the headphones or the battery caused it to shut off.Pros: corded option (cord included) when battery dies or with a non-BT device, headband adjustment stays put, quit comfortable, very good sound isolationCons: can't charge while using BT (but can still use cord), power/pair button is easy to accidentally hit when reaching for volume controlsFailed a 5-star, because while they're very good, I just don't feel they are *excellent*. Charging while using BT, <$150 price point, skip controls, better battery life would probably make them 5-start cans. Still I'm very happy with my purchase and would recommend them.

These headphones sound amazing (when using the cord), exactly what you would expect from an AKG with 50mm drivers. However there are three big issues with these:1. When using bluetooth and paired with a mac, there is static (hisses and pops) added to the audio. It is very distracting from the music, and makes the bluetooth almost unusable. Also, the headphones claim to be able to be used as a headset with microphone (they offer up a headset bluetooth profile), however the don't actually work as a mic.2. The paint finish wears off very easily.3. The headphones don't hold a charge well - if fully charged, they will be dead after 1-2 days even if they are off.Based on these issues, you are probably better off ditching the bluetooth functionality and using the K545 (same size) or the K550 / K551 (larger size, slightly better sound).
