After using the MDR-100AAP (h.ear on) for a couple of weeks, these headphones have become a great addition to my morning ritual. I tend to avoid bulky headphones in lieu of more portable in-ear headphones. However the Sony MDR-100AAP are so comfortable that I typically forget that I have them on. This is mainly attributed to the fact that the earpiece are both adjustable and rotatable. For home use, I find the headset more comfortable than the Sony Gold Wireless Headset particularly for prolong gaming sessions on the PS4. Secondly it is clear from the quality of the headset that Sony has really stepped up the game. The head has a smooth metallic finish, which I feel is appropriate to the price unlike the plastic casing of other (more expensive) branded alternatives out there. My own issue with the yellow headset is that it stands out a little too much. I feel that the blue one has a more subtle outlook, however each to their own. As for the sound, the headset isn't overpowering which might take some getting used to. I feel like the sound isn't powerful enough for public transport (or this may be due to the noise isolation) and I regularly find myself having to turn the volume up. Finally with the design, the headset folds up to become quite compact and comes with a matching pouch for storage. I'd personally prefer if the included cable was not a "L" shape connector, however this is easily fixed with a replacement cable. Overall I'm quite happy with these headsets and would not hesitate to recommend.

Really impressed with the new 'hear.on' hi res lineup - the MDR-100AP has the traits of the bigger brothers from MDR-R series and the headphones have the signature neutral/flat soundstage with great clarity. Only quibble with these is that its perhaps too flat for some tastes and lacks the warmth from the low end. Tried these with the new hi-res walkman and it sounded absolutely fantastic. The headphones are significantly lighter than most over ear headphones which means that its comfortable over wearing a long period of time - really impressed. Overall a great choice for those wanting something more, not to mention the flat cable stops the cord from tangling as much (thank you Sony!)
