Choosing between digital audio players can be difficult when one player emphasizes a broad Hi-Fi feature set and the other puts a defined storage and output package at a lower price. The TempoTec V6 and SHANLING M3X sit just $22 apart, so the best choice depends on the details you will actually use with your headphones and music library. The practical approach is to identify whether playback capability, battery information, storage, or connection format is your deciding detail, then let condition and price settle the tie.
Quick verdict
TempoTec V6 is the feature-led choice if your priority is its named DSD64-DSD512 support and 12-hour battery. SHANLING M3X is the price-and-capacity-led choice, with 32GB named in the title. Both players share black color, Android wording, Bluetooth, and a headphone jack, so those points do not decide the matchup. The decision turns on which of the remaining details matters most to your listening setup.

Where each player wins
TempoTec V6

TempoTec V6 wins for shoppers whose decision is driven by the number of named connection types. Its attributes include Bluetooth, USB-C, USB On-the-go, Wi-Fi, and Wireless alongside the headphone jack. That creates a concrete connectivity distinction without claiming that every headphone or source will work with every connection. The V6 is therefore the more appealing choice when those specific connection terms are important to your setup. Its case is based on the range of connections that are explicitly named, not on an inferred sound-quality ranking.
SHANLING M3X

SHANLING M3X wins on output-format specificity. Alongside the shared headphone jack, its connectivity details name 3.5mm and 4.4mm. That gives a shopper a concrete port-format distinction to prioritize. The key comparison is the named output detail rather than shared points such as black color or Bluetooth support. If those two output formats are central to your headphone decision, M3X offers the clearer match.
Product notes
TempoTec V6
TempoTec V6 suits a shopper specifically seeking an Android HIFI Music Player MP3, as that wording appears in the product title. Its Hi-Fi feature label adds a concrete reason to choose it without requiring a claim about sound quality. The practical limitation is the condition: the unit is open box and marked "No Original Packaging." That packaging detail matters if a complete presentation is important to you. The V6 therefore makes the most sense when its named format and Hi-Fi feature are the reason for choosing it, rather than when original packaging is the first filter.
SHANLING M3X
SHANLING M3X is a good match for a shopper drawn to the title's "Hi-Res Digital Audio Player" wording and Android format. The named 32GB capacity gives the choice a concrete library-related reason, without turning that number into a claim about sound quality. Its limitation is the used condition. The device is set to Japanese language by default and designed for Japanese outlets, details that can affect setup for some buyers. Choose the M3X when those title cues fit your needs and the used condition plus Japanese-language and outlet details are acceptable before you commit to it.
Final choice by use case
- Choose TempoTec V6 when DSD64-DSD512 support and the 12-hour battery figure are the deciding specifications.
- Choose SHANLING M3X when the $137 price and 32GB title detail matter most.
- Choose SHANLING M3X for the 3.5mm and 4.4mm output details if those formats are your deciding point; choose TempoTec V6 when the longer named connection list is more useful.
