LEAR is setting the new standard! With our new breakthrough after the LEAR A1d MKII that brings a higher quality sound !
 
With a reasonable price,our top-notch one dynamic driver earphones - LEAR A1d Ti Universal & Custom Fits are both available now!
 

​

 
 

​

 

 ​

 ​

 
A1d Ti was developed based on the footsteps of our renowned patented A1d MKII, such as:

• Patented 270º sound tuning design
• Precisely crafted metal sound coupler
• Metal tubing
• LEAR C8 wire (silver plated pure copper cables)
• German Viablue high-end 4% lead-free silver tin soldering

 
Ti is the chemical symbol for Titanium,representing our latest titanium diaphragm dynamic driver in the earphones.
The driver in the A1d Ti has a full-frequency impedance of 16 Ohm, matching its sensitivity to multi-drivers balanced armature earphones driven on a daily setting of smartphones with a low THD(Total Harmonic Distortion) puts the detail and clarity beyond those balanced armature earphones.
With the aforementioned features, the A1d Ti provides a personalized high-class enjoyment that is unmatchable in that price range!
 
A discounted price of HKD$300(Original price HKD$499 )for the LEAR BTC-01 is offered for pre-orders of the LEAR A1d Ti prior to the 31st August.

 ​

For example, users can alter between the reference position at 8 o’clock for a balanced frequency response to the equalized 12 o’clock position, or even the 4 o’clock position for an exaggerated bass for stronger rhythmic music.

Design:
A1d Ti provides both LUF &LCM versions.
· LCM (Custom Made) is custom made according to the ear impression of yours, giving a perfect fit without bothering about ear foam or ear plugs. Not only does that give a sound isolation, but a perfect fit in comparison with universal earphones that might be uncomfortable.
· LUF (Universal Fit) can be utilized with acoordinated ear foam, that gives possibility to share the music with friends.
 
All LEAR A series represents an “adjustable” frequency response on its sound, that its 270º tuning knob enables a tunable low frequencies response design. Users can alter the timbre of the earphones to a most personalized effect.
 
Special acoustic structure with a precision metal sound coupler and metal tubing alongside with C8  level high quality pure copper and silver plated copper wires that are soldered with German Viablue lead-free silver tin solder that gives A1d Ti a clear, detailed and realistic sound.
 
 
All LEAR custom-made earphones are all Hong Kong developed and made, for our insistence in quality control. We believe that LEAR customers are worth the higher cost for a higher quality.

Looks promising.  
 
I am very keen on single dynamic driver if it has flat frequency response out to 1kHz and not too uneven after that.  *EDIT: see notes below
 
Distortion seems really low from the spec.
 
*EDIT: Unfortunately not all the measurements were showing at time of my original post.  The shrunk down vert axis seems to downplay the goings-on after 1kHz, which don't appear ideal.  I don't think this matches the Harmann curve too well, which has response rising to 2-3 kHz and falling gently after that.

Nice! looking forward to see some impressions..

Seems like a winning CIEM... Single fast driver with a flat response curve that is tweakable!

By flat response curve I assume you are comparing it to some $1 earbuds?

I don't think my comment warranted the contumely. You make a good point though. I should have posted something to the effect that it appears that they can be tweaked to be flatter than the $1,400 CIEMs I recently sold.

Interesting.  Dynamic driver based CIEMs are much rarer than the usual balanced armatures.   I tend to prefer BAs but dynamics do seem to be better at creating  bass with a more realistic tone.

Just simply adjust the tuning knob on our A series ,like the A1d Ti, you will have both BA like and DD sound on the same earphone~

It triggers my interest that the graph shows a flat response. Seems like these will produce some detailed trebles. Staying tuned..

Hi, got a small question here.
 
Does this sound same to LEAR AE series? I've listened to LHF-AE1b, AE1d Ti, and AE1d universal IEMs but they weren't my cup of tee.
It just felt like they somewhat lack resolution and performance for their price range. I'd like to know how the new LCM-A1d Ti performs compared to those other LEAR IEMs I've mentioned.
 
Thanks.

Hi Damson,
 
As the A series internal acoustical structure is different against the AE series,
so that the sound is different, especially the mid and high, the A series is a bit clearer than AE series with standard nozzle,
However, there is optional advanced nozzle for AE series, so that once they've changed , the mid and high will also improved.
which will be closer to the A series but still not identical as well.
 
Thanks for your inquiry and support to our products!

Thanks for your reply. About the performance gap between AE series and the A1d Ti, is A1d Ti only "a bit" better than AE series?
 
I'm planning to order the CIEM version of the A1d Ti and I'm expecting this to sound way better than the AE series.

Their drivers are the same, only the internal acoustical changed, but any acoustical structure changed will influence the overall sound and performance.
Just like the change of Silicone eartips against foam tips .
