Very interested in these 2 aspects as well...especially for the steep asking price I'd hope both are included and perform very well.
Will there be an app, and if yes what features?

Multipoint? (Allow taking an incoming call from a paired phone while listening to music from a paired DAP, a key use case scenario).

@iFi audio I have a question: How was the power output for this product measured? We've seen that the Diablo was measured incorrectly, and the actual measured power output is only 1/8th of what iFi claimed. The stated output power for the GO pod is considerably higher than what other manufacturers state for their BT IEM adaptors. Can you provide a proper set of measurements, including analyser settings, for the GO pod?

...have you ever observed it connecting with your phone, while being stored inside its closed case?

Also, does it use the so called pogo pins / spring loaded connectors? Maybe, @iFi audio you could answer this question? :)
@iFi audio , a response to any of these questions, please?

@iFi audio , a response to any of these questions, please?

Sure:

1. Here's something for you all: https://www.head-fi.org/threads/crowd-design-for-ifi-app.967869/#post-17521636

2. Different testing methods may lead to differences in results, but the following are the testing standards and results for GO pod at our laboratory.

Input:sine wave 1KHz,0dB@ THD+N=1% into 16R.
Output:0.97V/58mW

Input:sine wave 1KHz,0dB@ THD+N=1% into 32R
Output:1.96V/119mW

Input:sine wave 1KHz,0dB@ THD+N=1% into 64R
Output:2.77V/120mW

Input:sine wave 1KHz,0dB@ THD+N=1% into 300R
Output:3.96V/52mW

It's worth knowing that:
  • GO pod has an automatic impedance matching function for load headphones. After the earhook is connected to the headphones, every time the battery compartment is released, the impedance will be automatically rematched based on the headphones connected
  • Directly replacing the connected load outside the battery compartment will not automatically rematch the impedance.
  • If the earhook is removed from the battery compartment, then the device without connection will automatically shut down after 3 minutes. After touching the earhook to turn it on, it will automatically match the impedance again.

3. We use regular connectors without any springs. Thanks!

One last, and very important, question from me:

Have you ever observed the Go Pod connecting with your phone, while being stored inside its closed case?

Just asking because this is, currently, my major issue with my UTWS5s...

I'm pretty impressed so far by the specs on display here and that AptX Adaptive Lossless HQ (at 96 kHz) is included. Having played around with LDAC on my computer via a FiiO BT30 Pro and a Creative BT-W5 (new BT 5.3) dongle, which supports AptX Adaptive HQ, using an iFi GO blu, I clearly gave the nod to Apt X Adaptive for tremendously better scaling and range, with completely similar sound quality. The added benefit about the dongle is that it costs nearly half as much as the BT30 Pro and is portable, with proper software.

I'm still kind of trialing the GO blu and am very keen to see and hear more about the GO pod.

I think you are confusing these codecs a little. Aptx Lossless is not out yet, is about 1mbps
Aptx HD has the highest bitrate, 576kps.
Aptx Adaptive has a slightly lower bitrate, (279-420kbps) but can change on the fly for best connection and lowest delay.

Hmm, I've read somewhere on here that AptX Lossless is basically another brand name for AptX Adaptive HQ at 96kHz and that Qualcomm wasn't sure about naming due to marketing concerns. Maybe that was wrong information :) Thanks for clarifying.

Edit: Gotcha, This article here sheds some light on my confusion.
Edit2: You mean "AptX Adaptive" in your last sentence, correct? @maegnificant

AptX Adaptive Lossless
It's called just aptX Lossless (at least officially, the proper name would be "aptX sometimes lossless" for its Adaptive nature) or aptX Adaptive r2.2 (sometimes even r3). And it's only supported by QCC517x+ and 6/7/8g1+ (not all phones).
It only works in 44.1 kHz (A2DP) and with ideal radio conditions.

It is out. Only a select phones (Asus zenphone 9 for example) have the Qualcomm chips for it. The phone has to state "Snapdragon Sound". The problem is that there are NOT a lot of headphones that have it (Nuratrue Pro being one of the few).

iFi audio GO pod + IEMs = brilliant wireless sound on the GO!

Plug a pair of ‘GO pod’ wearable Bluetooth DAC/amps into high-performance IEMs to make the
best-sounding true wireless in-ear headphones in the world.

1.jpg

Southport, England –
Joining iFi’s GO series of ultraportable headphone enhancers, the GO pod is a pair of wearable Bluetooth DAC/headphone amps designed to make any pair of corded in-ear monitors (IEMs) wireless. Given the quality of the GO pod’s circuitry, when combined with a well-chosen pair of high-performance IEMs, the resulting sound is far in advance of any ‘true wireless’ earbuds or Bluetooth headphones.

Using a pair of GO pods is simple. First, detach the cable from your favourite IEMs and connect the earpieces to the left and right pods. Then, pair the pods with your source device (a smartphone, for example) and hook the ergonomically designed ear loops behind your ears to ensure a comfortable fit… the result is unrivalled TWS (True Wireless Stereo) headphone sound.

To launch the GO pod, iFi is partnering with some of the world’s finest manufacturers of high-performance IEMs to make curated ‘GO Pod + IEM’ packages. Spanning both new and established models from 64 Audio, Craft Ears, Meze Audio, Symphonium and Westone, these special collaborations have produced six world-class pairs of TWS in-ear headphones.


Hi-fi separates for your ears

Comparing true wireless earbuds to the GO pod combined with a pair of high-performance IEMs is like comparing a smart speaker or all-in-one music system to a hi-fi separates system with a pair of well-chosen speakers. Sure, a smart speaker is compact and convenient, but a separates system delivers sound quality in an entirely different league.

True wireless earbuds – even the more expensive ones – rely on SoC (system on a chip) solutions to integrate the requisite tech into a tiny space. From a high-performance audio point of view, this is not ideal; amalgamating critical stages such as Bluetooth decoding, digital-to-analogue conversion and amplification saves space and reduces cost, but compromises sound quality.

2.jpg

The GO pod’s pliable ear loop hooks behind the listener’s ear

The GO pod is distinctly different. Each of these critical stages is designed separately and optimised individually to ensure excellent sound quality – like an audio system made from individual hi-fi components. In addition, much like top-level hi-fi speakers, high-quality corded IEMs are engineered for sonic excellence, combining multiple high-tech drive units to transmit sound directly into your ear canal. Connect a pair of these IEMs to the GO pod and it’s no wonder that the resulting sound is so much better than regular true wireless earbuds, given the level of audio engineering involved.


Stage 1: Bluetooth

iFi has gone to great lengths to ensure its Bluetooth technology is state-of-the-art throughout its product range, earning it a class-leading reputation. The GO pod continues this uncompromising approach, including certification for Qualcomm’s Snapdragon Sound platform and Bluetooth 5.2 for optimum range, speed and reliability. Bluetooth processing is handled by Qualcomm’s top-tier QCC5144 module, with its 32-bit, quad-core architecture and low power draw delivering excellent wireless audio performance whilst minimising drain on the GO pod’s battery.

As always with iFi’s Bluetooth audio devices, the GO pod is compatible with an impressive array of high-definition Bluetooth formats. LDAC and LHDC (HWA) are both supported to their maximum 32-bit/96kHz specifications, with LDAC’s highest 990kbps bitrate available to users of Android devices that support Snapdragon Sound (660kbps with other LDAC-enabled devices).

Qualcomm’s 24-bit aptX HD and aptX Adaptive formats are also covered, offering sample rates of up to 48kHz and 96kHz respectively, with the additional benefit of QHS (Qualcomm High Speed) providing an extra 300kbps of bandwidth. Other supported codecs include aptX Low Latency, regular aptX, AAC and SBC. This means that every possible source device is handled at the highest audio resolution its Bluetooth specification allows.

3.jpg

iFi’s GO pod turns any pair of high-performance IEMs into brilliant sounding true-wireless in-ear headphones

Another Qualcomm technology enabled in the GO pod is TrueWireless Mirroring. Although appearing as a single device when paired, both the left and right pods can receive Bluetooth signals – but only the one with the strongest connection acts as the receiver while the other mirrors the connected pod. If the listener moves position and the connection to the mirroring pod becomes stronger, they swap over so the mirroring pod becomes the receiver without interrupting the audio signal. Similarly, if the receiving pod is removed from the listener’s ear, the other pod becomes the receiver, ensuring a seamless true wireless stereo experience.


Stage 2: DAC

In addition to Bluetooth processing, Qualcomm’s QCC5144 chipset can be configured to perform digital-to-analogue conversion and headphone amplification too – but this is not the iFi way. Though more complicated and costly to design, the sonic benefits of separate, individually optimised DAC and amp stages are far more valuable to iFi than the savings made by one-chip-does-all solutions.

To that end, the GO pod incorporates two Cirrus Logic MasterHIFI chips – one in the left pod, the other in the right. This 32-bit hi-res DAC chip is dedicated to single-channel digital-to-analogue signal conversion in the GO pod’s circuit design, combining with a jitter-eradicating precision clock to deliver ultra-low distortion and high dynamic range – one of the key reasons why the GO pod unlocks better sound quality than true wireless earbuds.

Another factor is the hardware-based analogue volume control. The GO pod doesn’t rely on the software-based volume controls in connected digital devices, which can have a deleterious effect on audio resolution. Instead, adjusting the volume on the connected device controls the volume level in the DAC, rather than in the phone, tablet or computer.

To minimise pre-echoes and ringing artifacts, the DAC is designed with proprietary digital-interpolation filters that support multiple digital filter responses. This enables the GO pod to offer five filter settings, user-selectable to suit personal taste, musical style and format type – no true wireless earbuds offer such a facility.


Stage 3: amplification

Delivering a balanced output signal to each connected earpiece – another first for the TWS in-ear headphone scene – the GO pod’s amp stage has been carefully deigned to ensure ultra-low distortion and a silent background with high-sensitivity IEMs. With a power output of 120mW into 32 ohms, and an output voltage of 4V into high-impedance 300-ohm loads, each GO pod supplies plenty of gas to drive any connected IEM with consummate ease, without rapidly draining the internal battery.

To ensure its output perfectly matches the connected IEM, each pod auto-detects the IEM’s impedance and adjusts power accordingly. There are four settings – 16 ohms, 32 ohms, 64 ohms and 300 ohms – with the setting most appropriate to the connected IEM selected automatically.

Those familiar with iFi audio devices will know that the company uses discrete, high-grade components in its circuit designs, and the same is true of the GO pod. Devices such as TDK C0G multilayer ceramic capacitors and inductors from Taiyo Yuden and Murata deliver qualities such as low ESR (Equivalent Series Resistance) and high linearity, paying great dividends in terms of sound quality.


External affairs

Whichever connection type your favourite IEM brand uses, iFi has it covered. The GO pod’s detachable ear loop contains the IEM connector, and these are interchangeable – iFi has made ear loops for MMCX, 2pin, Pentaconn, T2 and A2DC connectors.

Weighing just 12g, each pod is designed to be lightweight and comfortable, yet robust and durable. The ear loops are mouldable to fit around your ears and the pods are water- and sweat-resistant (IPX5 rated), so no problem wearing them down the gym or getting caught out in the rain.

The GO pod’s ear loop can be detached and swapped for another with a different IEM connector

A built-in microphone utilises Qualcomm’s cVc noise suppression technology for excellent voice clarity, whether you’re making a hands-free phone call, chatting on a video call, speaking to the connected device’s voice assistant or even playing a game online. The aluminium panel on the front of each pod works as a touch control; simply tap to play or pause audio, skip forward or back, answer or reject a phone call, or engage the connected device’s voice assistant.


Ready? Charge!

The GO pod comes with a smartly designed charging case, with softly lined internal compartments and sufficient room to accommodate connected IEMs as well as the pods themselves. A 1500mAH rechargeable battery is built into the charging case; a pair of GO pods will play for up to seven hours on a single charge, while the case provides multiple recharges to enable up to 35 hours of playing time. The case supports both Qi wireless charging and USB-C fast charging.

Perfect partners

Rather than just launch the GO pod and leave users to choose the IEMs they think would work best, iFi has collaborated with some of the world’s finest IEM manufacturers to find perfect ‘GO Pod + IEM’ partners. As a result of this research, the first 1000 GO pods produced will come packaged with a pair of IEMs from a carefully curated selection.

All six ‘GO pod + IEM’ packages and their RRPs – which represent a saving on the individual prices of the GO pod and IEMs when purchased separately – are listed below:

GO Pod + IEM packagePackage RRP (UK)
GO pod + 64 Audio U4s£1299
GO pod + Craft Ears Aurum£1399
GO pod + Meze Audio Advar£999
GO pod + Meze Audio Rai Penta£1199
GO pod + Symphonium Meteor£799
GO pod + Westone MACH 60£999

The GO pod launches on 14th April 2023 at AXPONA (Audio Expo North America) and the 1000 ‘GO pod + IEM’ packages are available to order from this date. 60 days later – or when these packages have all sold through, whichever is sooner – the GO pod will be made available as a standalone product to combine with any pair of IEMs.

As a standalone product, the GO pod will have an RRP of £399. Each pair will come with two ear loops catering for MMCX and 2pin IEM connections; additional ear loops for Pentaconn, T2 and A2DC connections will be available at £29 each.

May I ask when your GO pod will be available as a standalone unit?
Also, is the case big enough to fit the adapters attached to the Sony IER-Z1R?
Thank you!
