These head phones are awesome for in ear; over the ear are good but as a female I am always worried about my hair so I got these and love them!!! The only thing is the clip used for the mic where is not secure so I've lost it and had to pay $4 for a new one.... Great sound otherwise!!!!!

April 25th 2018 Update: Amazing!!!!!

I've had these for many years and I absolutely love them. I use them in my travels all the time and they really help with the noise. Highly recommend them especially when in a flight with small kids around crying all the time! The it drwback is I lost the microphone clip but it's easily replaceable.

Very awesome, when I've got music playing I can't hear any outside noise. My only gripe is the battery pack is very annoying, especially when trying to exercise or walk as it needs to be held or it just dangles there & feels kind of awkward. Other than that, I think they are definitely worth purchasing.

I can't do without these earphones and wear them everywhere. Noise cancelling is really good - particularly for the size and saves having to carry around a big case when travelling. My only gripe is that after regular use the cord has shown a bit of wear with some exposed wiring but I guess this is to be expected after over a year of very regular use.

I puchased these earbuds last year and these work very well. the sound quality is very good and level sounding. The sound isolation started extremely well but after a bit of use they do start to lose the power to isolate outside sound, this is why I only give 4 stars but they are good for most tasks.

Outstanding little headphones. Sound quality is good, but the real attraction is the outstanding comfort and noise cancelling abilities. Can't believe how I flew without these, They have completely transformed air travel for me, the noise reduction is outstanding. Nothing like arriving fresh and relaxed after a flight, I didn't realise how much of an impact the aircraft noise was having until i tried these.

Only negative would be that the replacement parts from BOSE, in my case I lost the pouch to store everything, are very very expensive. They wanted $32.84 and $5.00 deliver to replace the $2 item. Canadians can get them delivered free for less than half that. Aussie tax...

These earphones are the best. A must have for the traveller especially for airplane travel. The science behind them is so simple but effective. The in ear buds are perfect for sleeping on long flights as well as producing good quality sound.
Recently, my unit earbuds had a charge problem only 14 months after purchase. 2 months out of warranty. When I contacted the store, they happily replaced my earbuds. Outstanding service! Congratulations to Bose and the team at Indooroopilly .

I agree 100% with the previous reviewer JMBAU so I won't repeat the points. You have myriad choices of noise-cancelling headphones - brands, specifications, features and price-points. But these are "in-ear" phones with no rivals because the technology is proprietary to Bose - for the moment. Hence, for the moment you pay big time for the privilege (RRP $399.00). Clearly a class of its own because Bose created that class. Also, I use it to drown out airplane noise (without listening to music) so that I can listen clearly and attentively to the flight attendant's all important and captivating safety instructions. How sad!
