The Panasonic RP-HC101 Slim Z are subpar on-ear headphones. They have a lightweight design and decent audio reproduction but feel flimsy and cheap. Ambient noise easily seeps into the ear cups and the weak noise cancelling is insufficient for even moderately loud environments.
The RP-HC101 are small, lightweight headphones that unfortunately disappoint with their flimsy, cheap-feeling build quality and their uncomfortably small ear cups. They have limited control options and the control module is surprisingly large, making them less portable than expected.
The RP-HC101K are so lightweight that they do not exert much pressure on the head or ears. They are unfortunately poorly padded and the thinness of the headband causes stability issues, which can make these uncomfortable if you listen to your audio a lot while on the move.
Button layout and the control options provided are functional but limited. The control options include a volume dial, a power switch and a monitor button that allows the user to temporarily suspend the noise cancelling to hear the outside world. However, the absence of call/music or track skipping controls is disappointing, as those options will have to be changed directly on the audio source or device.
The RP-HC101 are very portable on-ear headphones that are compact enough to fit easily into a bag, purse or pocket. They also fold up to take up less space. However, the control module can be a little cumbersome at times and can be a little frustrating to carry around.
Build quality is subpar for the RP-HC101 Slim Z. They're lightweight and the frame is relatively flexible but they feel cheap and flimsy. The metal headband is extremely thin and susceptible to warping under moderate physical stress. Also, the small ear cups are held to the frame by weak-looking joints that do not feel durable.
The RP-HC101 are decently stable but may fall off your head relatively easily. They are lightweight and have small ear cups that apply enough pressure on the ears, to maintain a stable fit during casual listening sessions. Unfortunately, they slip off your ears, while running and jumping. Also, the non-detachable cable is long and with the addition of the noise cancelling generator, easily gets tangled or hooked by something in the environment.
The Panasonic RP-HC101 are a mediocre sounding pair of closed-back on-ears. They have an average bass, a mediocre mid-range, and a lacking treble. Additionally, their bass lacks sub-bass and sounds boomy, their mid-range sound muddy, and their treble is recessed and lacks details. Also, they are prone to inconsistencies in their performance across multiple users, and don't have an open and spacious soundstage.
These headphones poorly isolate the listener. The small ear cups do not provide a great seal and fail to prevent ambient noise from seeping into your listening experience. The active noise cancellation is weak and ineffective, making the RPHC101K Slim Z unideal for use in even moderately loud environments. On the upside, they don't leak much sound.
The RP-HC101 like the HC200 have an outstanding battery life that easily lasts more than a 100 hours. Despite the poor noise canceling not being particularly efficient you will rarely need to change the AAA battery when used casually. However, they only have noise canceling as active features, which means they won't be the most versatile headphones.
The RP-HC101 Slim Z have an incredibly long battery life. They lasted up to 5 days of continuous playtime, which is excellent for long trips where you won't have access to a store, to purchase new batteries, for a couple of days. They can also be used passively by switching the noise canceling off when the batteries die. Unfortunately, they don't have any battery saving features.
