RBH Sound has collaborated with i.Tech to bring you the ProStereo™ H2, the first in-ear headphone featuring 24 bit high definition sound through Bluetooth® connectivity using both Qualcomm’s aptX‑HD™* and 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 up to 10 hours with a single charge.
"I just picked up a pair of the H2 headphones today, and I have to say, these are BY FAR the best sounding in-ear headphones that I've ever heard! Amazing lows and crisp highs. Amazing! You guys have, yet again, exceeded my expectations. Wow. " — C. Kotter
"Amazing! Music nirvana! I have the H2 and I can say without hesitation they are truly amazing! I love, love, love these headphones! I have in the past used wired Shure IEMs costing hundreds of dollars and I dare say these are quite superior in my judgment! (The convenience of the wireless form factor and the controls being at my fingertips are awesome but the sound is truly the main thing I love about these.) I use them with Comply Isolation tips (or Sport Pro, which is the same but with the added sweat-guard feature). After trying a few other types of tips, nothing else comes close for me. I'm using LDAC. I'm using a Samsung Galaxy S9 phone. At the time that I'm posting this, the LDAC feature in the S9 is only available via Developer Options (do an online search on how to access that.) Also, for best results, based on some inquiry it seems that Tidal (and Spotify) hi-fi downloads are 44.1/16 and in my experience when playing those files setting the LDAC to those specs seems better than using higher LDAC specs (and a forum inquiry suggest the same). At the least, it seems if the audio file is 44.1 it's best to set the LDAC to 44.1. Even though the DAC in the headphones upsamples, all indications are it's best to set the phone to match the source file if you know the specs. But test out the variables yourself." — J. Newman
