FWIW. http://www.tfzither.com/work.html The TFZ site have a brief introduction of each model. Apparantly the new T2 Galaxy is the upgrade version of Series 4. Also, massdrop is dropping queen and king pro now.

Hi yes. That's actually what i meant. Thanks for the more detailed input.

I just received mine and it's surprisingly good for its price! It sound even better when paired with BTR1! Comparing to the sony xb75 i owned previously, the bass is more refined and even more punchy than the sony's one. I kinda like the bass on this. It hit really deep. Listening to mike posner...

Its not the low battery signal. It happens when i paused songs or re-activate my bluetooth with it connected. There will be those kind of high frequency static sound emitting out for few seconds.. kinda like a mild version of frequency you will hear when you are on phone and there are incoming...

Mine had the same static high pitch sound you mentioned. I only hear it when songs are paused and when just powered on. Its like a long high pitch beep that is quite annoying and abit too high that can be unbearable sometimes.

Thanks much! I will look into it.

Oh how do we update the btr1?

Think you are right. Might be i'm using spotify. Volume button changes the volume on the btr1 only. The volume on the phone stay the same.

Yes volume button work. The middle button serve no function for me except to activate surround effect. Wondering if is because im playing through spotify..

Wow good for you. Me pressing on the middle button does not dp anything. Except if i double tap activates the surround effect. Im using samsung s7 edge.

Hi neozengar, ur btr1 have play/pause function? How do u do it?

Hi grininja, good question. I have always been using it with my nuforce edc with braided cable (no inline remote) and so have nv think about this before. Just tried it with my sony xb75ap with inline remote. The remote on my sony doesn't work. U can only talk through the mic from the btr1...

Hi Mitchell, sorry i'm 1 year late. You should have your answer by now! Good choice btw!

Hi vilasman. For your wife, AKG N60NC wireless is one of the best option if you want smaller and quality matching bose and sony. I believed B&O H9 is Over-ear but even so, they are not as large as bose and sony. H8 is the ideal on-ear verison. B&O are more expensive than AKG, but they do have...

I have tried with Iphone X. For me, it sound almost the same with using BTR1 or straight through lightning port. It does not have that kind of drastic differences as from my S7 Edge. I Believed the BTR1 does not support AAC. But nontheless, good as a wireless option for your wired IEMs. Enjoy...

Btw, double tap on the round button of the btrx put it into wide surround mode which further expand the soundstage. Good for mobile gaming/videos.

Btw, im using spotify downloaded in max quality for referenc Yes i did. It sure improves SQ but still quite far behind iphone. Eg. I have to turn the volume of s7 to 75% or higher to get the desired volume and clarity.. whereas iphone x i just need 40-50%. without btrx, it sound slighty...

Hi. Mine is the eynox version. Perhaps i came from using iphone previously, felt that s7 audio output straight from jack is lacking in volume so much. In fact, i just tried the btr1 with my s7 edge side by side comparison with iphone x with jack adaptor (using same songs). Btr1 still sound...

Good to know! I'm incline to get it anytime soon!

Totally agree. Im using s7 edge and it improve the sound quite drastically for me in my opinion. Tested with my daily iem: nuforce edc from massdrop and it changes the dynamic of the music. It became so much louder, more clarity and tighter bass. Tested with other in ears as well.. soul sl49...

N40 is the flagship of the Nseries. N20U is the cheapest of the series with single dynamic driver model but non-detachable cable. N40 cost alot more than the CH9T though. CH9T is around the price range of N20U. Awesome. Thanks!

Thanks Lurk650. Do u consider it an upgrade from AKG N20U? Unsure if it worth getting as i already have the nuforce and akg. Thanks!

Thanks pete! I'm not really a basshead, just wanted a little tad more bass than the AKG. I love the AKG N20, but wanted to try something different and better. Thanks for your recommendation, will definately check out the iBasso IT01!

Hi, I'm currently using Nuforce EDC from massdrop and AKG N20U for IEMs and is looking for an upgrade from these 2. Looking for something that sound even better and more bass. I have been eyeing the CH9T awhile.. just need some advice if CH9T is any better from the ones im using now. CH9T...
