Hidizs AP100

Verdict

The Hidizs AP100 is a great media player. I look forward to future firmware updates but in the meantime the UI is quite useable, and the unit gives a clean, uncluttered sound with a decent amount of power. This is an amazing first effort which begs the question; whatever next from Hidizs?

Pros

  • Built to last
  • Neat, useful carry case
  • Large clear display
  • Firmware can be updated
  • Sounds superb at this price point
  • Internal data/file storage

Cons

  • Button layout may need getting used to
  • Micro SD card could be easier to insert and remove

If you like your brand names to look like the first line of an optician’s eye chart, the Hidizs is certainly worth considering – the name might take some getting used to, but it’s plain to see that this player is getting some covetous glances! The Hidizs AP100 has some stiff competition in the low-cost DAP (Digital Audio Player) market, not least from FiiO’s ‘X’ range. The Hidizs AP100 appears to be a halfway house between the Fiio X3 and X5 in terms of size and cost.

Key Features

Inputs and outputs are well represented; both headphone and line-out sockets are present on the top and a separate 3.5mm coaxial in and coaxial out can be found at the base of the unit. Volume buttons are side by side on the front, and on the left side there are both the source/SRC and EQ buttons. Being capable of playback at up to 24bit/192KHz, the SRC button can select the bitrate the player works at. The EQ button scrolls through available presets, and the user can define their own preferred EQ settings.

The case is a really nice design; it is enough to protect the AP100 without bulking it out, and has an understated look much like the player itself. The case is made from a synthetic leather-like material which looks quite durable.

The battery lasts a good long while, and although no precise measurements were taken, there was a good amount of playing time between the ‘low battery’ warning and the player turning off – maybe an hour or two. My experience with the Fiio X3 gives little chance to enjoy music before the unit runs out of power – perhaps 20 minutes at most. Helpfully, the status of the battery is given as a percentage on the screen when charging the unit, so we can make an informed choice of whether to leave the unit charging or to take our chanced with what power is there.

First Impressions

The buttons on the Hidizs AP100 are lovely to press; there’s a great chunky feel to them and they are good solid buttons which will last. Someone said that they are reminiscent of Gameboy buttons – certainly the placement of the volume buttons on the AP100 give a flavour, but they are the kind of buttons that let you know they’ve been pressed – there’s no doubt involved as with touch screens and wheels. The only problem is that Hidizs saw fit to add separate buttons for ‘fast forward/rewind’ – usually the same buttons are used for track skip and forward/rewind, but not on the AP100. Also the ‘back’ button is on the right of the other navigation controls, which makes it feel like a forward/select button; this may lead to a few wrong turns for the uninitiated but it’s easy to get used to.

Sound Quality

Compared to the Fiio X3, the AP100 is a little more accurate and coolish but this is not to say that the AP100 is harsh. Listening to unyielding and brittle-sounding early 80s pop such as Duran Duran is fine on the AP100 but the X3 just gives it a bit more warmth and roundness to a presentation – the AP100 wins in terms of detail.

Compared to the Fiio X5, the sound is extremely similar; the X5 comes across as just a little smoother up top. Soundstage and imaging are similar, but with just a hint of edge to the sound on the AP100 which brings up harmonics a little more.

Added to that, the AP100 holds enough wherewithal to power some less than sprightly headphones such as the HifiMAN HE-400 very well, so the need for a separate amp is lessened.

Summary

An excellent player with a bulletproof design. Solid and reliable, the Hidizs AP100 gives a similarly solid sound and user experience. The sound quality and power gives amazing results, however less sensitive headphones may need a little help. The Beyerdynamic T1, at 600 ohms/102 dB gets up to a good level, but quieter recordings will be lacking in headroom. In our opinion, it bridges the gap between Fiio’s offerings and Astell and Kern’s AK100 but at a very favourable price.

Score 9.0

DUNU DN-900 Earphone Review

Verdict

The DUNU DN-900 is a well built, hybrid in-ear headphone. The bass is punchy without overcrowding, with spacious mids and smooth highs – these earphones perfectly combine power and detail.

Pros

  • Frequency response can be fine tuned
  • Generous range of extras/accessories
  • Very clear bass and mid-range

Cons

  • High-frequency roll-off (if you like a brighter sound)
  • Case oversized for everyday use
  • Tuning rings easily lost if not careful
  • Cable can get tangled

As with all segments of the headphone market, the £100 – £200 bracket is hotly contested with innovation pushing sales as well as gimmicks. The hybrid drivers within the DUNU DN-900 are becoming commonplace among IEMs, but the tuning rings which are supplied with the DN-900 are not so commonly found. Given that we all have our pet sound signatures and preferred frequency responses, have DUNU released a self-adjustable gem?

Key Features

Perhaps most unusual about the DN-900 is the inclusion of the tuning rings; it’s always nice to have a bit of tweakability and it’s fun to experiment. However, be sure that you are changing the eartips and rings while sat at a table, or similar. The rings can jump off the nozzles and roll out of your life for ever if you aren’t careful. It would have been better to have a more ‘trouser clip’ style ring which stays on the nozzle.

First Impressions

Naturally enough, once out of the packaging, the first thing I noticed was the professional quality Pelican-style case. It’s a lovely item if bright yellow is your thing but it won’t fit in a pocket, nor is having your IEMs packed away in a bag or case the most practical place to have them. I would be utilising another case or pouch from somewhere else, while this case might lie unused in a drawer.

Sound Quality

The sound seems very mid-centric at first, with strong yet well shaped bass response. The most noticeable thing is the higher-frequency roll-off but this takes only a minute to get used to. I tried the rings in turn..

Silver gives a good bass grunt with midrange clear and even, and the higher frequencies rolled off. Blue appears bassier in the mid-bass area with a more pronouced and open midrange, while red is bassier again with some more low-bass creeping in and mellower mids. High frequencies are not affected by any of the rings but the blue’s effect on the midrange sits next to the highs better for me.

After trying the DN-900 with the Astell&Kern K120, I was very happy with the sound. Driving bass underpinned some very fluid and involving mids, with higher frequencies just managing to show their faces enough to keep the party atmosphere going.

The following impressions were gained using the blue rings and the AK120:

Frankie Goes to Hollywood – Two Tribes (Blank and Jones reconstruction)

The bass has good texture and impact going into the sub-bass slightly, mid range works well with male vocals and backing. Soundstage is good and wide with a great sense of space. Imaging is also good. The rolled-off highs did not give any problems.

Dub Syndicate – Mafia

Bass is very full and impactful with good slam. It is quite boomy on this track but dub calls for it! Midrange is still clear and separate – the piano parts are very distinct. Highs lend a touch to harmonics but otherwise linger in the background. Soundstage is as wide as the music requires, delay is headshaking.

Summary

The DUNU DN-900 is perfect for the tracks that were tried with them. They will satisfy any basshead but will not add bass which is not there and cloud things – midrange is spacious and lively. Again, the higher frequencies may be a problem for fans of this part of the frequency spectrum; but if like some you’re a little sensitive to it, the DN-900 should fit like a glove.

Score – 9/10

Best Headphones for Portable Players

Listening on the go is becoming more and more popular – especially that now you can store your whole library of lossless audio on to a compact player like the FiiO X3, FiiO X5 or even the Astell&Kern AK120.

With the potential to have the highest quality audio in your pocket you will want to complement that with the headphones you use. This article will cover how to choose a portable headphone and suggest some of our favourites.

When buying headphones or in ear earphones for a portable player there are 3 main qualities you will be looking for:

Compact

As you will be more than likely using the headphones while travelling you will want them to be small enough to fit into a bag or even fold up for easy storage. You will also want them to be a size that won’t get in the way whilst moving from busy train to busy train.

Closed Back / Sound Isolating

As these headphones will probably be used in public, you won’t want the sound of your guilty pleasures spilling out to the rest of the train carriage – nor will you want to hear the loud music being played by the youths at the back of the bus. Closed back or sound isolating headphones are perfect for this, as they reduce the amount of sound leaking and help block out external noise.

Easily Driven

The majority of portable players such as iPod, iPhone, Samsung, Sony etc. can give great sound quality but they don’t have the most powerful headphone amps on them – when this is the case you want a headphone that is easy to drive so you can get a good volume out of them without maxing out your player.

In ear headphones

The ultimate portable solution are in ear isolating earphones as they tick all the above qualities – here are a selection that I would recommend:

SoundMagic E10 (£34.99)

The go to in-ear for under £60.

Final Audio Heaven II (£89), IV (£199) and VI (£599)

Refined sound with great bass and sharp detail.

GermanMAESTRO GMP 8.35 D (£160)

Neutral sound with crystal clear detail.

Beyerdynamic T5p (£880)

Studio quality sound on the go.

Ultrasone Edition 8 (£1099)

Audiophile quality sound with superb isolation.

Open back

Now if you don’t need complete sound isolation and would prefer an open backed headphone then there a some very good ones to choose from:

Koss Porta Pro (£29.95)

The classic portable headphone.

Grado SR80i (£99.95)

These are very hard to beat for under £100. HiFi quality sound on the go.

SoundMAGIC HP200 (£229)

Smooth and fun sounding with great detail. Very comfortable and good isolation for an open back.

Headphone amplifier

And finally… If you have got your heart set on a headphone that is more difficult to drive then do not fear! Adding a portable headphone amplifier into the chain will solve this issue.

FiiO E12 (£109.99)

Lots of power, bass boost, sturdy build quality and detailed sound.

So hopefully this article has helped you decide on your new headphone – but if you have any questions then do feel free to get in touch and we will be happy to help!
