RBH Sound has collaborated with i.Tech to bring you the ProStereo H2, the first in-ear headphone featuring 24 bit high definition sound though Bluetooth connectivity using either Qualcomm’s aptX‑HD or Sony’s LDAC technologies. The H2 also uses a built in AKM+ 32 bit DAC/Amplifier with a 384kHz sampling rate to reproduce the audio signal with the highest resolution possible no matter what Bluetooth audio codec is being used by your connected device. The result is the best sound attainable in a Bluetooth in-ear headphone. You’ll be amazed at the detail and dynamics of the full range music produced by these in-ear monitors. The RBH edition of the ProStero H2’s includes specifically fitted Comply foam and SpinFit silicone tips that extend frequency response and improve isolation and comfort for an unparalleled listening experience. Battery Performance: • Talk time: Up to 9 hours*† • Music time: Up to 9 hours*† • Standby time: Up to 200 hours** Estimate with a fully-charged battery. As with any battery-powered device, when powered off, the H2's battery charge level will diminish slowly over time.† Actual battery performance and listening time will vary based upon listening volume and distance between Bluetooth devices.

Excellent sound but too much noise from the cable
I have been looking for a earbud product with bluetooth wireless connection that supports aptX HD. Seems like this is the only one on the market? Please let me know if there are others. I mainly wanted to take advantage of the aptX HD chip on my Lg G6 phone to enjoy HiRes music. Below is my review:Pro:-The sound quality is good as expected. Each earphone product has its own sound characteristics, it's a matter of finding the one that fits your taste. Luckily, I like the sound signature of this pair. Unlike other earbuds, it does not utilize a V-shaped sound response, but is rather balanced in different parts of the spectrum. Some people might have hoped to hear more in the higher notes. I sometimes do hope so too, but other times I feel it's right about how much I wanted to hear. The mids are the highlights, and there's enough tight bass there too. It's got a lot of details, thanks to the high bit rate processing. For some of the songs I tested, I could hear details that I never heard of before, in all different parts of the spectrum. Sound stage and imaging is so so, but I wasn't expecting miracles from earbuds anyways. It's not bad, but it's not great either.-Playing movies: it doesn't have the latency between audio and video (you hear the voice after you see the lips move), mostly likely thanks to the aptX HD codec.-Battery and connection: I charged it full before first use, and although I didn't do a complete battery draining test, after 4 hours of continuous playing, the battery indicator shows there's around 60% juice left. To me this is good enough. It also stayed connected to my phone without dropping it.Cons:-It's a pity that I have a huge issue with this product. When I wear the earbuds, the cable generates a large amount of microphonic noise which interferes with the music. The materials that made up the coating of the cable (it looks like fabric?) rubs with whatever it touches and generates the noise. Even the slightest turn of the head will generate noise. This makes it very hard to enjoy the music. For a pair of $200 earbuds, this is totally unacceptable. This is the main reason that I gave a 3-star rating.For this reason, I am on the fence whether I should return the product or not. I guess I will find out soon. If you are reading this and know any way of reducing the microphonic noise, please let me know by replying here. Thanks.

Lackluster. Much better quality (and cheaper) options on the market for BT headsets
Sound quality:Lackluster at best. Some bass was evident but I'm more of a bass head so these didn't really do it for me. Sound quality was okay I guess but it didn't have as wide of a range as MUCH cheaper options out here. Honestly if you want the best sound from a Bluetooth headset, get the KZ ZSR IEMs and the Yinyoo TRN Bluetooth headset. You'll spend around $60 total, have better battery life and unbelievably better sound quality experience than what these ProStereo H2s offer.Battery:Battery life seemed pretty standard. Nothing to write home about but definitely not annoyingly bad.

Build quality poor but sound quality is great.
I have been looking for a upgrade from my Jaybird X2. I came across a video on YouTube talking about the H2 and the performance of LDAC. After receiving the headphones I was not impressed by the build quality. The body of the headphones are sharp hard plastic corners and stiff cord that doesn't lay well around your neck. The only upside is the sound,but you have to find the right size tips for your ears. At first they didn't sound good with the tips that were already installed. So I installed the Comply premium isolation tips and that made a world of difference. On my note 8 I went and made sure to check the box for LDAC and I had amazing sound. But over the past couple of days I couldn't get used to the build quality and the horrible cord design. I really wanted to like them but they are not compatible. I am in the process of returning them. Also I got about 8.5 hrs of play time.

The best (and sole?) option for aptX HD in the gym
I have purchased these to replace some beats in-ear bluetooth headphones which have lasted several years of sweaty gym playback.In my research I discovered aptX HD which seemed to be the best option for bluetooth audio and the qualcomm page listed these as my sole option for in-ear/sweat resistant. In terms of audio quality they sound far superior to what I have endured with the beats, the sound stage is noticeably more detailed and the bass whilst somewhat less intense is very accurate.The build integrity/quality whilst not as visually "sophisticated" as more well known competitor products is nonetheless quite substantial and I have no real criticisms. I am also surprised and impressed by the inclusion of aftermarket ear tips, which I look forward to trying out - right now the standard pre-attached tips are performing quite adequately.One small critique is the provision of a soft vinyl pouch to store them in as opposed to a more semi-solid zip container which the aforementioned beats headphones came with - I've actually reused the beats container to store these in since I don't trust the pouch to protect them when tossed in my gym bag with all the other gear I store in there.These also support LDAC which my HTC U11+ was obsessed with wanting to use despite it not being appropriate for noisy 2.4GHz environments where a consistently high SNR is required to deliver such a high bitrate - I had to enable developer mode on the phone to force aptX HD and then we were in business. Shame on HTC for not providing an easier way to choose aptX HD over LDAC.

Last pair of iem's I'll ever need
They sound great. Not bass heavy but more natural. I can tweak more bass with equalizer if needed but still not too heavy. Wire is real stiff and isn't going get damaged anytime soon. Very well built set of iem's Should last a very long time. Very happy with purchase. I don't know if I would pay the extra $$ again knowing what I know now but I'll probably never need another set.
