66 Audio-bts Pro Bluetooth Headphones Aptx Ll

Recommended Posts

The person who sent me the firmware was Caroline B. I had another exchange with an Emily O., who appeared clueless and just copied and pasted a long blurb about no plans to support LDAC or aptX-HD, and audio listening tests and groups and the difference between our current aptX and aptX HD was non-existent.

I'd give it one more try and put ATTN Caroline B. Unfortunately I don't have her direct email, just support@66audio.com.

If that doesn't work Amazon has great return policies.

Good luck!

How did you know that was Emily's response.  Lol.

They sent a follow-up email asking how things were going and Emily's response didn't make any sense? Probably a copy and paste response.

Overall its working good with the aptX LL firmware. Occasionally it'll freeze up when I try listening to music on my phone or pc. Hooking it up to the charger snaps it out of the freeze. Please let me know if you release any further refined aptX LL firmware.

Thanks, sdbirder

Hi sdbirder, 

Thanks for your message. We currently have no plans to support LDAC or aptX-HD. We’ve thoroughly ran audio listening tests and groups and the difference between our current aptX and aptX HD was non-existent.

BTS Pro and PRO Voice uses the latest generation of Qualcomm aptX as well as our own 66 SoundEngine DSP which further enhances the audio profiles in numerous ways. Additionally, the headphones use very unique and high-end stereo drivers with optimal frequency response curves and low THD for the best listening experience.

Let us know if you have any more questions.

Best, 
Emily O.

sdbirder,

Welp, I switched over to the BTS Pros, installed the latest firmware and they do not connect with the Equinox as  aptx-ll (no plus sign with the bluetooth symbol) so I don't know how you got yours working in aptx-ll mode.  Are you seeing the plus sign on your Equinox display when the BTS pros are connected?

Ok - got that straightened out an downloaded from the link you posted above instead of the link 66 Audio support sent me and the headphones updated to APTX-LL and confirmed with the "+" symbol on the Equinox so we are good to go.  Great backphones for summer use and being water resistant don't mind wearing them at the beach and in foul weather.  Not made for a full dunking by they will get the job done in waist deep water.  Great sound, great ergonomics and if you shop around, they can be snagged for less than $100.  I recommend these for warm weather detecting.

I also used to have a Deus and really liked the backphones. They're light, and great if you want to wear a broad brim hat. After reading this thread I bought a pair of BTS Pros, and using the firmware link provided by sdbirder, updated them to APTX LL. Thanks for the info and the link...awesome!

I too am coming from the Deus, and I have tried the Miccus Sr-71 Stealth phones, and they are great, but the summer heat is unbearable with those phones.  I bit on the BTS Pros, and out of the box they pair but NOT in Low Latency mode on the Equinox 600 (as expected).

I tried to run the Windows update from their site (1.08), and it gives:

Firmware Update Error

Program was unable to connect to the headset

Please check again that cable is connected and headset is powered off.

Error -2

 

I did all the pressing of the 3 buttons, standing on my head, facing east, etc, nothing changes.

I am going to let them charge overnight and try again.

The updater posted by sdbirder also failed giving an error on that command prompt window it opened:

 

HidDfuCmd.exe upgrade 0a12fffe00 aptx-ll-enable.dfu

HidDfucmd.exe, version 2.6.2.632 Release

Copyright Cambridge Silicon Radio Limited 2012 - 2015

Error running upgrade command: Invalid Sequence (HidDfuConnect must be called first)

Press any key to continue...

 

I assume a regular Windows 10 PC should work fine for either of these updates?

Do I have to run in XP SP3 mode, administrator, some sort of special mode?

I have tried 2 desktops and a laptop (all windows 10 fully updated) , and the result is the same.

I am using the cable they sent with the device, is there a special port I need on my PC?

The Android app shows the firmware is at 1.07.

 

Thanks!

 

UPDATE 3:45 p.m. Central

Got word from BTS support via email, and they said to try another USB-C cable.  I looked all over town, and just about gave up but when pumping gas, they had one at the checkout counter.  Worked the first time.  Of course I did the 1.08 update from BTS first (no Low Latency), then the secret one offered by sdbirder and voila.... + sign on Equinox 600 indicating APTX Low Latency Enabled!

I thought you would have figured that out by reading my post with the exact same experience.  Lol.  Glad you got it to work, finally.

      Dear Friends ....  Have purchased the Equinox 800 and Would like to know if anyone has had or used this coil and would like to share your thoughts on/of this coil. I realize that it has not been around all that long but perhaps some of Our Forum has had some hands on experiences with it? Any an all remarks would be appreciated.  Considering on purchasing! Thank you very much! Co

      My old headphones got all beat up over the summer plowing through the woods so I snagged a pair of Garrett Stow Aways for my Tejon. I was really surprised how good the audio really is on them. They do fit a little tight and are smaller but have a really great range of sound. Now I need to re-learn my sounds.
      Anyways I didn't spend much time out, maybe half hour or so and left the 10x12 coil which kills me in trashy areas but I did get a nice smooth hit on this little 18k rose gold ear ring with a few diamond chips 0.7g.  Was only inch or so deep nothing to brag about.

      My new T2 arrived this week so I decided I'd take it out for a test run today, I haven't bothered detecting football fields before, it never really crossed my mind to do so especially small town football fields that barely ever get used.  I think the last time I even saw people on this thing was about a year ago and they were riding a horse 🙂
      I guess back in time it was probably a popular place and my results today show this.  This is going to be more of a picture story as the pictures tell 1000 words! 
      I started using the T2 with Mars Tiger coil and within two minutes of arriving I had my first coin, then another, then another..... it was nuts, coins everywhere and very little junk, I was finding nice old coins, possibly one of my oldest in a while too

      Silver 🙂

      1938 British Penny

      The T2 was getting good depth, easily hitting on coins with good ID's, another silver!


      1948 Penny -  Now NZ currency, not British like the older Pennies, we used some British currency until 1967. 
      Prior to 1933 United Kingdom currency was the official legal tender of New Zealand, although Australian coins and notes were also generally accepted.
      The first New Zealand penny was minted in 1940. The penny ran until 1965, when New Zealand stopped minting pre-decimal coins in preparation for decimilisation in 1967.


      I have no idea what this thing is

      This is the football field I was detecting, under the goal posts and along the end of the field had a good collection of coins,  I guess from all the diving with the ball and coins in the players pockets, I don't know much about football, probably the only NZ male who has no clue about the game 🙂

      My oldest find of the day, a British 1912 One Penny

      It was quite deep down but the T2 banged on it real hard with a solid ID.  At this point I decided I'd go home and gear up better as this place obviously has a lot of good old coins.  I was only using my T2 with Carrot and Lesche digging tool which was hard work with all the coins being so deep.    I wanted a bigger coil to cover more ground but there was no way I was going to strap on the 15" Teknetics coil to continue using the T2 as it weighs a tonne.  I opted for the Equinox with it's 15" coil  and almost straight away after turning it on, another coin

      1950 NZ One Penny.  I left the bit of dirt on the coil up the top it came out of, I love when you get the impression of the coin in the soil.

      Another silver, 1934 Shilling

      This is the hole it came from, I always recheck my holes and I'm glad I did, another target in the hole, then another... this was crazy


      3 Silvers in the hole so far, 1934 Shilling, 1934 Shilling and a 1946 Sixpence, I was sure this was it but I did another check and off to the side of the hole, ANOTHER SILVER

      Another 1934 Shilling, 4 silvers in one hole, incredible!   Someone had a bad day.

      1964 Sixpence... the coins just kept coming, all old ones.  No longer are they made of silver in 1964...

      Nice and deep though
      +++++
      My first modern coin, a $2

      But look how deep it was, it was deeper than a lot of far older coins.... weird!

      Another two in one hole, just one cent coins from back when NZ had one cent coins.

      Another coin leaving a cool impression of itself in the soil, just a one cent I think

      It sure a lot of ground to cover, I'll be at this place for weeks... plenty more coins to find I'm sure.  Time to head back to the car, with my coil to the soil.

      Another for the road 🙂 Double sided impression on the soil with this one.  I couldn't possibly put up a photo of every coin find as there were just too many, all in about 3 hours detecting.

      The good stuff

      The bad stuff... not a bad ratio, good stuff far outweighed bad stuff, unusual for me.... I'll be back there tomorrow.... and the next day.... and the next day 🙂

      On the advice of others on this forum, I called Minelab today to inquire about the play I've had in the shaft on my Equinox since day one. When I called back in 2018, they wanted me to send the whole detector in to get looked at. This time they said they would send the three pieces my way, and I just need to send the originals back to them. Has that been your experience for those in the same situation?
