Shanling H2 Unboxing and Deep Dive

2024-01-31 by bustatech

I have received my Shanling H2 last week, and have been using it since then. So far the unit has been working very well, and for my non audiophile ear, it sound great. One thing I noticed immediately is that the background noise for Shanling H2 is very very quiet. Using my Fiio FH7, I can still pickup some background noise when using Sony NW-A105 and iBasso DX160, but on Shanling H2, the background is very very quiet.

I have done an Unboxing Video:

And a deep dive into the functions of Shanling H2:

iBasso DX160 Replace Battery

2024-09-192024-01-22 by bustatech

I recently bought a broken 2nd hand Ibasso DX160 (2019 Version) with its battery and the rear cover glass damaged. My plan in getting this unit is to replace the rear cover glass and the internal battery myself. I have verified with the previous owner that the unit was working well before the battery was damaged.

After searching for where to get the replacement rear cover glass and replacement battery, I found the contact for Paul, (paul@ibasso.com) from the iBasso DX160 official thread at head-fi.org.

Shanling H2 Portable DAC/Amp

2024-01-15 by bustatech

Shanling has recently released H2 Portable DAC/Amp which caught my attention. As I previously modded my Chord Mojo to have its Bluetooth receiver (Chord Mojo Bluetooth Receiver), I noticed that I like this type of form factor – a DAC/Amp with a built-in Bluetooth Receiver.

I find myself using this setup extensively, especially when paired with my wired IEM. It seamlessly connects to various audio sources such as my Android phone, DAP, Desktop PC, Laptop, and tablet. Given the increasing trend of devices abandoning the traditional 3.5mm headphone jack, this form factor becomes a crucial solution, providing a high-quality wireless 3.5mm jack.

Under this DAC/Amp form factor, Shanling H2 is the latest addition. The previous releases are Shanling H7 and Shanling H5.

Digital Audio Player Replacement Battery from Aliexpress

2024-09-192024-01-04 by bustatech

One of the key features of a Digital Audio Player (DAP) is how long its battery can last. In the pursuit of extending the battery for DAP, I found out that some seller on Aliexpress sells high-capacity batteries that is 50% higher than the original batteries.

The 2 batteries that we will be studying today are:

YKaiserin 2100mAh Battery for Sony Walkman NW-A10x

Normally for Sony Walkman NW-A105 (the one I owned), the standard battery capacity is 1285mAh. The battery by YKaiserin is claimed to be 2100mAh, which is around 60% additional compared to the original one. You can refer to this post on how I add a 2nd battery to my NW-A105.

HSABAT 4800mAh Battery for Ibasso DX160

For Ibasso DX160, the standard battery capacity is 3200mAh. The battery by HSABAT is claimed to be 4800mAh, which is 50% more compared to the original one.

Sony NW-A105 Battery Mod

2022-11-17 by bustatech

Sony NW-A105 is a very well-known Android DAP that was released around the end of 2019. As discussed in many forums (head-fi forum) and reviews, a significant downside of this Android DAP is the Battery life. Some members in the forum even shared steps to disable background services and run the DAP in airplane mode which helps improve the battery life, but it is still mediocre.

In this article, I will share on how I mod the battery on my A105 to increase the battery capacity.

Chord Mojo Bluetooth Receiver

2022-03-19 by bustatech

I have recently purchased a 2nd hand Chord Mojo and for me, it sounded great and definitely an upgrade over my Galaxy Note 9 3.5mm jack.

However, there are 2 major complaints/issues that I have with Chord Mojo:

The lack of Bluetooth receiver function. It requires Chord Mojo to be always connected through wire to either my Android phone or my PC/Laptop.
The use of Micro USB port that is outdated for the DAC and charging. All my other device charge through USB C.

In this article, I will share how I upgraded my Chord Mojo to solve both my Bluetooth receiver and Micro USB port problem.
